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’ll contribute to the design and development of full-stack features, collaborate closely with product, design, and backend teams, and ensure the scalability and maintainability of our applications as we grow. 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.

    • Enjoy owning your work and seeing it deploy safely in production

    • Are excited ~ finally! ~ enable a true digital revolution in healthcare

    • Thrive amid the changing landscape of a growing and evolving startup

    • Enjoy collaboration and solving unique problems across teams, including the AI team

And it would be awesome if you were...

    • Experienced in building and scaling high quality consumer-facing UIs

    • Familiar with our tech stack [React, Tailwind CSS, Typescript, Go, Python, REST, GraphQL, Terraform, AWS, Docker]

    • Experience with the tools that support our work [Amplitude, Sigma, Auth0, Metaplane, DataDog, Claude Code, Atlassian]

    • Knowledgeable about application security & HITRUST compliance

    • Experienced in working with HIPAA-compliant APIs

    • Familiar with the FHIR R4 Standards and/or TEFCA standards

    • Optimistic about how AI can enhance products and assist in building them

We will offer you…

• Opportunity to work alongside a passionate team that is determined to help change the world (and have fun doing it)
