The moment
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
