Job Location:

Anywhere in the U.S. - Serif Health is a remote-first company with team members coast-to-coast. We hold on-sites at least quarterly in rotating locations across the U.S. for team members to get to know each other and collaborate in-person.

Our initial interview is a takehome, giving you the time, space, and comfort to show your best work and ability to work independently and communicate solutions asynchronously. It will cover real-world problems we see in the existing transparency data space.

Followup technical interviews, will cover a few pragmatic topics. These are open-ended and we don’t necessarily have solutions to them. We’d love to understand the process you’d take to solve these, understand your creative & problem solving process, and hopefully get you excited about the challenges we’re working on.

For the team fit interview, you'll meet other members of our engineering and leadership teams who you'd be working with on a day-to-day basis. These are a chance to understand our working style and our motivations for working in this space.
