We're at the start of the most interesting engineering chapter in our company's history. The team is small, the surface area is large, and the decisions we make over the next year — about architecture, tooling, hiring, and how humans and AI build software together — will shape the product for years. We're hiring the engineer who can be at the center of that. ## The role
As Principal Engineer, you're the senior-most individual contributor on a small, high-leverage team. Your main job is to ship new products and systems, fast, at a high quality bar, with AI as a core capability in how you work. You set the bar — for product judgment, code quality, design, production rigor, and hiring — through the example of your own work. You also own and maintain the infrastructure and backend that carry the product. It's not your full-time focus, but you understand the stack deeply enough to keep it healthy, debug it when it matters, and make the right architectural calls when they come up. You'll work directly with the VP of Engineering and partner across Product, Clinical, and Security. ## What you'll do in your first 6 months
Primary requirements
A track record of using AI to build real products and systems dramatically faster than the old way — with no loss of quality. You have strong, lived opinions about where AI tools shine and where they lie, and shipped work that proves it. - Excellent product judgment. You understand the user, you know what to build and what to cut, and you make the calls that a junior engineer would defer up. - An unusually high quality bar for code, design, production rigor, and what "done" means. - Founding-engineer DNA — or an ex-CTO/VPE coming back to the code. You're effective in small, high-trust teams with wide scope and ambiguous problems. Important, but not the most critical
Solid backend experience in Go or Kotlin (strong preference for both) — enough to own services, not just pass them through. - Competent with AWS or GCP (preference for GCP) and with production Kubernetes. You can debug it, evolve it, and know when to stop improving it. - Full-stack comfort across Node/TypeScript services and React/Next.js on the frontend. ## Compensation & Benefits
