At Diagnose, we're building the technological stack of systems for healthcare teams and agents. AI is fundamentally changing how teams function day to day, and we’re shaping the tools this new era requires.

It is the reason we move fast, stay focused, and care deeply about getting the details right. There are no committees, no approval chains, no side quests. You know what you are responsible for, you have the context to make good decisions, and you are trusted to see them through.

We are early enough that the work you do now will shape the company for years. In healthcare, the details are never small. We are building a team that understands that and holds itself to it every day.

  • Translate design specifications into performant, pixel-perfect interfaces

  • Contribute to frontend architecture decisions as the team grows

What we're looking for

  • 4 or more years of frontend engineering experience in a product-led SaaS

  • Strong proficiency in React and TypeScript

  • Sharp eye for design detail and a high bar for UI quality

  • Experience building for performance and accessibility

What we offer

  • Competitive salary and meaningful equity at Series A

  • Remote-first with flexible working hours

  • Annual team offsite and conference travel budget

  • Health, dental, and vision coverage

  • Home office setup stipend
