Top Engineering Values

Each team is asked to select, explain, and rank their top 8 values in order of importance.
  • Engages with Community

    Providing healthcare services to diverse populations is at the core of what we do.

    Our mission is to help everyone lead the healthiest life that science and medicine can offer. One way we do that is by partnering with organizations to help them deliver preventive care and wellness screenings, COVID-19 management and mitigation programs, and other basic healthcare services directly to their employees, whether in the office or remote. Our software also supports public health programs by connecting communities to local sites and labs for testing, immunization, and other care, while easily integrating with existing systems. Last but not least, we support end-to-end research programs, including patient enrollment and consenting, testing, return of results to the research sponsor and the patient, and ongoing patient engagement. For example, we received a $4.6M grant to collaborate with the National Institutes of Health’s “All of Us” genomics research program, reflecting diverse populations.

    At the onset of the pandemic, we knew there had to be a better way to provide direct-to-population testing. In addition to being at the forefront of sequencing new variants, we’re also helping our communities by developing models to help keep kids in school. As an engineer who joins the team, the work you do will have a real-world impact from day one.

  • Creative + Innovative

    We’re leveraging automation and robotics to help us scale.

    By focusing on bringing critical services (like vaccinations and simple diagnostic tests) to users directly (at offices, schools, or even at home), we can transform the way public health happens and make it much more convenient. In order to do that successfully, we place a large emphasis on both engineering and design innovation in everything from physical specimen collection kits to detailed genetics reports. Our products are also expanding into other healthcare domains such as mental health support and sexually transmitted disease programs.

  • Flexible Work Arrangements

    We support a remote culture!

    While our HQ office is in Burlingame, CA (and we have a laboratory and satellite office in San Francisco), we’re remote-friendly. Our team members span different time zones in the U.S., so there’s a great deal of flexibility in how, when, and where you get your work done. For example, Tally, one of our software engineers, enjoys core workouts and started the #abs channel on Slack to lead afternoon abs workouts as a fun pick-me-up. She’s also taught an employee-led-class on how to knit and crochet!

    We try to have as many overlapping hours as possible, but you are more than welcome to create your own schedule. Some engineers who live near an office like to come in once or twice a week to collaborate in person, but it’s not required. We will also happily fly in engineers for team events if they are interested in traveling.

    Having to work weekends is generally rare, but if you do (or you’re required to travel over a weekend day), we have a “burn day” policy, where exempt employees can work with their manager to take a burn day off without counting it as a PTO day. We also have monthly recharge days during months where we don’t have paid holidays (which are scheduled ahead of time) – so every month you’ll have at least one day off! And if you’re thinking about expanding your family, we’ve got you covered with both generous paid leave and an inherently flexible remote work policy. We offer 18 weeks of parental leave for all regular full-time and part-time employees and cover 100% of their base salary, reduced by the amount of any company short-term disability and state-paid benefits employees may receive. Last but not least, we recognize that living in unprecedented times is stressful, and our team is flexible to accommodate individuals’ needs.

  • Internal Mobility

    There are multiple ways we encourage career growth.

    We believe career growth is more than just moving up the metaphorical ladder, which is why we support internal mobility. For example, Justin joined us six years ago when we were working out of a shoebox. Since then he has been an IC engineer working across the stack, a Tech Lead mentoring others on the team, and an Eng Manager leading various teams through the pandemic. Similarly, Wendy joined eight years ago and has taken on several different roles. In 2020, she was our Head of Design and since then she has been a PM, a Designer, as well as a VP of Product and UX. She’s currently leading a team to build a brand new product at Color. Another great example is Stephanie, who went from Genetic Counselor to Support. She now leads technical support engineering.

    Whether you prefer to level up as an IC, move into management, or take on an entirely new role and expand your skill set, we’re always looking for ways to help you take on new challenges and get where you’d like to be in your career.

  • Rapidly Growing Team

    We’ve grown from ~140 employees at the start of the pandemic to ~700 at the beginning of 2022 – and are continuing to expand.

    It’s clear that genetic testing is at the beginning of an exponential growth trajectory. By innovating in our software and lab processes, we’re well-positioned to make genetic testing more accessible than ever. While the pandemic led us to quickly expand and provide more COVID-19 testing and vaccination sites, we believe the pandemic has only underscored the need to use technology to broaden access to healthcare. Whether it’s administering flu shots or blood-pressure tests or providing more access to genetic testing and counseling, there’s a huge opportunity to bridge gaps in healthcare.

    In terms of funding, we announced our $167M Series D in January of 2021, with a valuation of $1.5 billion. It’s also worth noting that we intentionally raised our Series E at a time when we didn’t need more funding: we raised $100M for a $4.6 billion valuation in November of 2021, less than a year later. We’re quickly adding to our team and this additional funding will power both exciting new health technology and greater infrastructure for governments, employers, and other institutions that care for large populations.

  • Start-to-Finish Ownership

    Engineers drive projects from inception to completion.

    Whether it’s a project that takes weeks or just a few days, engineers have a large amount of responsibility and ownership. One great example of this is how we built an intake app for COVID-19 testing. In March of 2020, we quickly mobilized our diagnostic genetics testing infrastructure to respond to the COVID-19 pandemic. Testing hundreds of people a day required us to rethink our manual intake process. Five engineers built our digital intake app in just one week by starting with a detailed design document, working in tight pull requests to keep the code as up to date as possible, and keeping open lines of communication with the entire team. At the end of the day, we look for folks who are excited about finding the simplest solution to a problem that will make the biggest difference for our users.

  • Continuous Delivery

    We have a very active codebase and solicit input from the entire engineering org.

    The life cycle of a project often starts with product requirements and engineers writing up an engineering design review. Unlike at other startups, Color invites the entire engineering team to participate in the design review of every design. On Tuesdays, the whole org gets together for an hour to take a look at all of the proposed engineering designs and provide feedback. Not only is it a great way to get a broader set of eyes on our work, but it also helps avoid silos with other teams and supports continuous delivery by keeping feedback loops tight.

    Since most teams work on a weekly (or bi-weekly) sprint cadence, engineering designs can be implemented and shipped quickly. Production code deploys twice a day and we rely on both unit tests and end-to-end testing to ensure code ships smoothly. Rather than having a QA team, we rely on engineers to own their code’s quality through the CI testing, monitoring, and reporting process. Hand in hand with our focus on continuous delivery, is an emphasis on delivering reliably, and we’re always working to improve the performance of our database and queries. We integrate and test daily. This unique blend of systems engineering and bioinformatics enables us to build a revolutionary product that can easily scale, while keeping costs low.

    We’re intentional about our onboarding process and try to lift up the entire engineering org by passing down best practices. To be on the same page, we try to make the codebase a clean, pleasant place to be with practices like automatic linting and formatting. As Anastassia, one of our senior software engineers says about the codebase, “It’s a nice house to be in.”
