We’re looking for an experienced Senior Engineer to join our Applications (App) team, which delivers the core web and embedded applications our customers use every day. The ideal candidate is passionate about building intuitive, reliable, and scalable user-facing products that empower healthcare providers to access and act on critical patient data.
As a member of the App team, you’ll work on everything from React-based user interfaces to the APIs that power them.

You enjoy thinking about the full flow of data—from UI interactions to API design to backend systems—and are comfortable owning services end to end. Our stack includes React, TypeScript, GraphQL and RESTful APIs, and AWS services like ECS, Lambda, and DynamoDB.

- Enjoy owning your work and seeing it deploy safely in production
- Are excited to ~ finally! ~ enable a true digital revolution in healthcare
- Thrive amid the changing landscape of a growing and evolving startup

- Knowledgeable about application security
- Experienced in working with healthcare data and APIs
- Familiar with the FHIR and/or TEFCA standards
