The Handbook

Our mission is to accelerate progress in medical imaging by sharing knowledge, creating tools, and providing quality services to our clients, with the ultimate purpose of improving patient health. We do so while providing meaningful, flexible, and financially rewarding careers to our team.

This handbook describes how we develop great software while maintaining enjoyable, flexible, and financially rewarding careers. We wrote it for a few different audiences.

If you are considering joining us, this handbook should help you decide by providing insight into how we work.

If you just joined us, this handbook should contain everything you need to know to hit the ground running. We are excited that you are on the team.

If you have been with us for a while, then you are probably checking to see whether Black Friday is a company holiday (it is).

If you have hired us, this handbook may be rather dull, but we are glad that you are curious about how we work.

This handbook is hosted in a git repository. If you have a question that you wish the handbook answered, let us know. Please make a suggestion in #general if you are a team member, or email us. Team members can also submit pull requests with proposed changes.

Please note, links to the GitHub repository and Slack will only be accessible to Innolitics employees.

Our Values

We do our best to keep our values at the center of how we work. Our company values are to:

Pursue a deep understanding.

Continue learning.

Build quality software.

Treat our clients ethically.

Understand the business context.

Communicate clearly.

Be responsible for our work.

Be pleasant to work with.

Respect the autonomy of fellow developers.

Make the world better.

Enjoy our work, and relax.

We suspect most of these values are not controversial. Still, if you disagree with any of them, or if you want us to add or modify any of them, please initiate a discussion! Here are a few examples of how our values have changed over time:

After we hired our first developer, we added “We love working with talented people, regardless of their age, ethnicity, sexual-orientation or background”. A few months later we added “gender” to the list.

We added “We financially contribute to open source projects that we use” to the list because, as a profitable company that uses many open source projects, we feel we should give back.

We clarified “we write automated tests to ensure our code works (and continues to work)” by re-writing it as “we write automated tests to guide our design and ensure our code continues working” to highlight our belief that tests not only help catch bugs but also improve our designs.

Originally, one of our values read: “We don’t prescribe solutions to problems; we allow developers to independently discover their solutions first”. After some discussion, we changed this to: “We avoid prescribing up-front solutions to problems; we prefer allowing developers to independently explore their ideas first”. This change was made because we realized that sometimes it is too time consuming to allow everyone to explore their solution, especially junior developers working on problems that have been solved many times in the past. In these cases, we believe it can make sense for the more experienced developer to prescribe a solution up-front. We prefer to have junior developers to find their solution first because it is educational and can lead to better solutions (perhaps a new technology was developed recently, or the junior developer comes up with a new approach).

This last example highlights that many situations we run into as developers are not black-and-white. Our values are a foundation for discussion, but often we are weighing competing goods. For example, “We enjoy experimenting with new technologies so that we can use the best tools for the job” and “We use technologies with the best interest of our clients in mind, even if they are less appealing to us as developers” can be competing goods.

Most importantly, if you feel that we are not following our values, say something! We can not stress this enough. It is essential that you say what you think.

Several months after adding our commitment to contribute to open source software, we still had not done so. Someone brought this up, and in response we setup our open source contribution page.

Medical Imaging Software Services

We love working on medical imaging software. Our work helps doctors diagnose and treat patients in the clinic and helps researchers make breakthroughs in the lab. We believe that software has the potential to transform the medical imaging industry, and we are excited to be front and center in this transformation.

Medical imaging software is a specialized field, so we don’t expect everyone who joins our team to have a strong background in it. Many of our projects have challenges that are not unique to the medical imaging. That being said, you do need to be interested in medical imaging, have some mathematical background, and have a desire to learn more to be a successful part of our software team.

We Are a Remote Only Company

We are a remote only company. We don’t have a central office, and most of our communication occurs in Slack, video calls, and email.

Working remotely allows for a flexible work schedule. For example, David’s wife is a nurse. She works night shifts and during many weekends, but is frequently off during the work week. If David did not have the flexible schedule that remote work affords, he would see his wife much less often. As it is, he can work longer days when she works, and work shorter days when she is off. Also, because he works from home, he can see her when she wakes up in the afternoons.

Although flexible work schedules are possible for non-remote workers, they are harder to arrange or take advantage of. When everyone is working in the same location, there is a lot of pressure to be “visible” at meetings and during the typical work day. Going on an afternoon errand run is often impractical. Conversely, when a company employs only some remote workers, it is easy for those workers to get left out of meetings and company activities.

A remote only company encourages everyone to focus on their value-added instead of hours worked because value-added is more visible than long hours in a remote setting.

There are many more benefits to working remotely which we will not list here. However, there are also important-to-mention disadvantages to working remotely.

Working from home is not for everyone; it can be lonely, and it is easy to go stir crazy. It is more difficult to separate work from your personal life.

If you have never worked remotely before, it is worth thinking through how you will manage or respond to these various issues. Some people prefer to work from a co-working space on some days. Other people like working from coffee shops in the mornings. David has two “users” on his MacBook, one for his personal life, and one for work. This allows him to turn off notifications when he isn’t working.

It is more difficult to develop strong relationships with remote teammates because we can’t grab a beer after work or chat in person. There are a few ways we alleviate this. The first is via conversations on #random. Next are our 10x Discussions about various medical imaging and programming topics. Finally, we have retreats at least twice a year. More about our 10x discussions and our retreats in a bit.

Labor Law Posters

We don’t have physical offices where we can hang labor law posters, so we store posters online in a Google Drive folder. The documents in the root of the folder are federal law posters. State- and city-specific documents are contained in subfolders. Please review the posters for your state and ask if you have any questions.


Part of our mission is to provide flexible working conditions for everyone on our team, including the flexibility to move without changing jobs.

If you move within the same state, please be sure to update your address in Gusto.

If you are considering moving to a new state, please discuss with a partner. Due to complicated state-varying labor laws and tax implications, we can not guarantee that we can support any move. Chances are high that we can, and we will try hard to make it work one way or another, but the earlier the move is discussed the better.

Our Team

We are a small team. We have nine full time members as of October 2018.

We are planning on growing the company substantially over the next few years.

Working on a small team means we have relatively little structure and more personal responsibility. As an early member of our team, you will have the opportunity to grow with the company, and to influence how the company develops.

Project Structure

We work on projects of varying sizes. Our typical engagement lasts about a year, although we have been working with some of our clients for several years. Typically, everyone is assigned to a single project at a time.

Each project has a project lead who is ultimately responsible for the success of the project. The project lead’s responsibilities include:

We usually have client progress meetings on Mondays, and additional meetings as necessary throughout the week.

10x Time

On Wednesdays from 2:30 - 5:00 PM CST we have 10x time (we choose Wednesdays so that we can travel on Monday or Friday). Some weeks we’ll skip 10x time if there is an impending deadline or many folks are on vacation. We do not have a 10x time during the week of Thanksgiving or the Wednesday in between Christmas and New Years.

We have two types of 10x time:

  1. Discuss an article, video, or book chapter. Everyone reads the chapter from 2:30 - 3:45 PM CST, and we discuss on a group video call from 3:45 - 5:00 PM CST.
  2. Three-week mini-project. During the first two weeks we work on the project and discuss in Slack. On the third week, we work from 2:30 - 3:45 and discuss from 3:45 - 5:00 PM CST. If you prefer, and your client obligations allow it, feel free to lump all three learning sessions into the third week (i.e. work on the mini project all day).

Usually, only a single partner will participate in mini-projects. Also, we suggest pushing your mini-project work onto GitHub.

We try to pick topics that are fun and interesting and will make us better developers. Please feel free to suggest topics in #learning. If we end up using your suggestion, please add a new item to our list of previous discussions. We try to choose the discussion material or mini-project Friday afternoon of the previous week. You can see a list of our previous discussions here.

If we are having a good discussion, we will often go 15 minutes or so past 5:00 PM CST. If you have plans and need to duck out, but can’t get a word in to say so, just drop out of the call and leave a comment in Slack; everyone will understand.


We meet once each year to have some fun and get face time with one another. The retreats usually begin Thursday afternoon and end Saturday afternoon. The destination always changes. We cover the travel, housing, and food during the retreats. The retreats are meant for Innolitics employees only, but people often delay their flight back and make a long weekend or vacation out of the trip.

Unless there is a very good reason (and please let us know as soon as possible), everyone is expected to attend all of our retreats.


We keep travel to a minimum, but we occasionally must travel for


When you travel, keep receipts for food, transportation, and accommodation expenses. We can not reimburse expenses if there are no receipts, so please be careful to keep them!

Please use your best judgment when purchasing food, flights, and hotels. Keep in mind your time is valuable. It is worth spending an extra $100 to get a direct flight or to avoid needing to fly out at an uncomfortably early time. Ask David or Yujan if in doubt.

If you are driving your own car, track how many miles you drive, ideally by taking a photo of the dashboard at the start and end of your trip. We use the mileage numbers to calculate the IRS standard mileage rates for reimbursements. For 2017, this was $0.53/mile. Note that the standard mileage rate’s include the cost of gas, so please do not include receipts for gas.

You must create an expense report to be reimbursed. We provide two different ways to create expense reports, which are described below. After submitting your expense report, you should be reimbursed on the next payroll cycle. If you are traveling and you need to purchase a flight, feel free to send an expense report with just your flight and a second report with all of your other travel expenses.

Expense Reports With Expensify

Download the free Expensify app. After creating an account, you can:

Once all of your receipts are uploaded, download a PDF copy of the report and email it to

Expense Reports With Excel

Fill out this spreadsheet and send it and the images of the receipts to

Flexible Schedules

We value our flexible work schedules, however, this does not mean that we can work anytime we wish.

Performance Reviews

We have mid-year reviews and end-of-year reviews. We also have a short review three months after you join Innolitics, primarily to check that you are happy with the position and it meets the expectations you had when you accepted the position.

When you join Innolitics, we will setup a private GitHub repository which will only be visible to partners and yourself. For now, these repositories will have a single file,

Reviews occur as follows:

  1. A partner (usually the partner with whom you have worked the most since your previous review) will reach out on Slack and schedule a time for the review.
  2. You should read through the list of questions, written below, and write out any thoughts you may have in a new branch in your repository.
  3. During the review, you and the partner will talk through:
    • The answers to the review questions
    • Your performance since the last review
    • Your personal growth goal
    • Your annual raise and bonus (only during our end-of-year review)
  4. After the review, write out notes from the discussion in the new branch you created, and then create a pull-request from the branch and assign it to the partner who did the review.

Here are a list of questions to consider before your review. Please let us know if you can think of any questions to add to this list.

Communication Tools


Email is best for non-urgent communication that requires a formal or well thought out response.

Our preferred email signature is:

First Last
Job Title, Innolitics

Our preferred email signature when communicating with possible sales leads is:

First Last
Job Title, Innolitics
Medical Imaging Software Development & Consulting


Slack is best for most everyday communication. Here are some rules of thumb for Slack communication:

Slack Notifications

In a remote working environment, a Slack mention is the equivalent to walking over to someone’s desk and tapping on their shoulder. The impetus is on everyone to not over-use mentions as they are disruptive, but when someone does mention you, you are at your desk, and not in a call, respond quickly! By “quickly” we mean within 5 - 10 seconds.

The best way to respond this quickly to mentions is to use Slack desktop notifications (and audible notifications if necessary).

In order to avoid being inundated with notifications, we suggest telling Slack to only notify you about “Direct messages, mentions & keywords.” You can set this from your Slack preferences. This article has more details. If you have any channels where you want to be notified of all messages (e.g. a client’s channel), use the channel specific notification preferences to turn notifications on for “All new messages.”

If you need a solid block of time to focus on a technical problem free from interruptions, we suggest setting your status to indicate as such. David tends to use the Robot icon for this (e.g., /status :robot_face: head down coding).

Slack Video

We use Slack for most video calls; we use Skype as a backup.

The person who initially mentions starting a call in Slack should initiate the call; this convention avoids delays that can occur when both members are waiting for the other person to call.

When on a client call, follow some video call etiquette:

External Communication

Respond to client emails promptly during the business week, even if it is just to say that you will respond in full at a later time. Clients really appreciate quick and prompt communication.

Informal writing is sufficient for internal emails. However, when emailing clients, please pay extra attention to your grammar and spelling. We highly recommend using a tool like Grammarly to double check your writing. Let us know, and we can set up an account for you to use.

Be sure to read client emails slowly and completely so that you are sure you address all their questions and concerns. It is easy to miss important details or comments after the end of a long quotation block.

Internal Communication

It is usually best to include a time-zone when indicating times, however, in the absence of an accompanying time-zone, assume that times are in CST.


To retain flexible work schedules, we do not have a morning “standup” unless the client requests one. Instead, we post our progress in the #standup Slack channel.

The frequency and level of detail included in your standup messages should reflect the project and team members you are working with. If you are tightly collaborating with several people, daily standups may be worthwhile. If you are the only person working on a project, a weekly update is likely sufficient. Please post updates at least once each week. It is nice for everyone else on the team to be aware of your work. Even if nobody needs to know what you are working on, writing some details about your work is worthwhile. Doing so increases opportunities for collaboration by telling everyone what you are working on, what you are struggling with, and what technologies you are experienced with.

If you are working on more than one project at a time, then please provide details about which projects you worked on in during a given week or day. This will help project leads allocate time when billing our clients.

If team members or your project lead request that you post standups more frequently, please do it.

A typical standup should include:

Members typically receive two weeks of paid time off during their first year, three weeks for their second and third year, and four weeks each year after that.

We also have Christmas Eve, Christmas Day, Thanksgiving Day, Black Friday, Memorial Day, July 4th, Labor Day and New Years Day off. If these Holidays fall on weekends, we observe them on the closest weekday. See the Gusto company calendar for the precise holiday schedule. Please note that this list does not directly match the US federal holidays. For example, we do NOT observe Columbus day (a federal holiday), while we do observe Black Friday (not a federal holiday).

Notify your project lead in advance when you want to take a vacation, and be sure to request it using Gusto with as much notice as is possible.

One of the perks of working remotely is having a flexible work schedule. Because of this, sometimes we will take off during the week but will make it up over the weekend or in the evenings without taking vacation time. Taking off during the week depends on the demands of the project you are currently assigned to; for example, often we have client meetings during the week. Also, sometimes it can be convenient to work on a holiday and instead to take off another day. Feel free to do this if it works for the client projects you are on.

Payments and Compensation

We run payroll every two weeks. The last payroll of the year will include any annual bonuses. Payments are made using Gusto.

Retirement Savings

We have a 401(k) plan that allows for traditional and Roth contributions. We provide an automatic 3% of your salary to the plan whether or not you choose to invest. Our 401(k) plan provider is Guideline, and the plan has many low-fee mutual funds available. You become eligible to contribute to the plan after six months of employment.

No Health Insurance

We do not currently provide company health insurance.

Open Source Contributions

Each quarter we donate $500 to an open source project. We decide which project through discussions with everyone in the company. You can see previous projects we have donated to here.

Information Security

Our information security policies are designed to help us protect:

Failure to follow these policies may result in disciplinary action.


Health Information is information in any medium that originates from a provider, insurer, or other healthcare entity, and relates to physical or mental health, or to the billing for healthcare services.

Protected Health Information (PHI) means individually identifiable health information.

Electronic Protected Health Information (EPHI) means PHI stored or transmitted in electronic form (e.g., on a computer hard disk).

A breach is the actual or potential acquisition, access, use, or disclosure of PHI other than for approved uses.

A workstation is an electronic computing device, for example, a laptop or desktop computer or smartphone, or any other device that performs similar functions, and storage media connected to it.

A covered system is a workstation or server which may contain or store EPHI.

A covered connection is a connection between a covered workstation and a source of EPHI. The following are examples of covered connections:

Workforce members are employees, subcontracted staff, or others with roles that may interface with sensitive information.

A covered workforce member is an Innolitics workforce member who is able to make a covered connection.

A project lead is the Innolitics employee (typically a partner) who is managing a particular client project.

A security incident is a potential data breach or other possible compromise in the confidentiality, integrity, or availability of protected information.

Password Management

A secure password is at least 8 characters long, is unique, is not repetitive, and either includes multiple types of characters or is very long. These are examples of good passwords:

These are examples of bad passwords:

Here are our policies for password management:

If you are unfamiliar with LastPass, these video tutorials are helpful.

Although we don’t typically look at it, LastPass keeps a log of when different people log in to different Innolitics LastPass accounts—so you may not want to add personal logins to your company LastPass account. Instead, we recommend setting up a personal LastPass account, and linking the two.

Email and Web Security

Before sending a message that contain sensitive information, double check that the recipient address is correct. It is helpful to mention in the message that the contents are sensitive and should not be shared with others.

Spear phishing is an increasingly common tactic that can result in a compromised account, web browser, or workstation. A spear phishing message can be disguised to see legitimate; often the links embedded in the message are designed to exploit a web browser, the attachment exploits the application that interprets it, or the email itself has a call to action to divulge information. Once exploited, a workstation might download a malware payload that can execute instructions defined by the attacker.

A bulletin was published by the US Department of Health and Human Services on the topic, if you are curious to see the guidance given to the healthcare industry in general.

There are a variety of pretext attacks on the web that are similar to phishing. Innolitics requires multiple layers of security controls to mitigate the risks of attacks like these.

Workstation Setup

All covered workstations and systems must implement the following security controls:

  1. Require a password, fingerprint, or facial recognition to log in,
  2. Automatically lock after an hour of inactivity,
  3. Encrypt internal storage at rest, and
  4. Automatically update operating system and application security patches, or are manually updated once each quarter, and
  5. Antimalware agents set to automatically update malware definitions.

If feasible, non-covered workstations should also be setup in this way. If you opt to use manual updates, we recommend setting a repeating reminder so you don’t forget.

Working with Sensitive Information

In order the limit the proliferation of sensitive information beyond the control of Innolitics and to meet our agreements with the data originator, sensitive information should only be stored and viewed on covered workstations. Before you start working with sensitive information on a new workstation, inform your project lead so that they can record details of the host for tracking purposes. We need to keep a record of where sensitive information is stored, so that we can be sure it gets deleted when no longer needed.

Innolitics requires the following practices when working with sensitive information:

Purging Sensitive Data

When finished with a project, it may no longer be necessary to retain information, and it is risky to hold on sensitive information longer than necessary. When you are sure that data are no longer needed, follow these guidelines to purge the files they cannot be inadvertently reconstructed.


We frequently use SSH to access remote servers. Here are policies regarding SSH:

Working in Public Places

Avoid working with sensitive information in a public place when feasible. If unavoidable, position your screen so that is not easily visible by others and be careful to lock your workstation before stepping away from it. Try not to leave your devices unattended.

When working on publicly shared internet connection, use a virtual private network service to tunnel your traffic through the untrusted connection. Tethering to a mobile phone is a more secure option.

Annual Training and Audits

If you work with EPHI, you will need to review these documents once each year and configure your devices to meet these security guidelines. Also, your project lead or Innolitics’ Security Officer will ask you a series of questions regarding how your devices are set up.
