Parsley Health is rebuilding primary care around root-cause, whole-person medicine. The company is at the start of a significant engineering chapter, and this Principal Engineer role is the senior-most individual contributor on a small, high-leverage team.
Your primary responsibility is to ship new products and systems quickly at a high quality bar, with AI as a core capability. You will set the standard for product judgment, code quality, design, production rigor, and hiring through the example of your own work. You'll also own and maintain the infrastructure and backend that power the product—not as a full-time focus, but with deep enough understanding to keep systems healthy, debug critical issues, and make sound architectural decisions.
In your first six months, you'll ship new product surface area rapidly, leveraging AI tools like Claude and Cursor to compress development timelines. You'll establish AI-native workflows and patterns for the team, ensuring AI leverage becomes a team capability rather than individual practice. You'll maintain healthy foundations by owning backend and infrastructure quality, CI/CD hygiene, observability, and architecture decisions. You'll also set the technical hiring bar, conducting technical screens and helping strong candidates commit to the company.
You'll work directly with the CTO and partner across Product, Clinical, and Security teams. The role is hybrid with 2–5 days per month in the NYC office, though full-remote candidates in EST/CST are considered if they can work on an EST schedule.
Required: A proven track record of using AI to build real products and systems dramatically faster without quality loss, with strong opinions about where AI tools excel and where they fall short. Excellent product judgment—understanding users, knowing what to build and cut, and making calls that junior engineers would defer. An unusually high quality bar for code, design, production rigor, and what "done" means. Founding-engineer DNA or ex-CTO/VPE experience—you thrive in small, high-trust teams with wide scope and ambiguous problems.
Preferred: Solid backend experience in Go or Kotlin (both strongly preferred), competence with AWS or GCP (GCP preferred) and production Kubernetes, and full-stack comfort with Node/TypeScript services and React/Next.js frontends.
