Principal Product Engineer (Full-Stack)

About the role

The role is as Principal Engineer at Parsley Health, a company rebuilding primary care around root-cause, whole-person medicine. The candidate will be part of a small, high-leverage team, setting the bar for product judgment, code quality, design, production rigor, and hiring.

Responsibilities

• Ship new product surface area, fast. Take new ideas from zero to production with a quality bar that makes the rest of the team raise theirs.
• AI is how you compress weeks into days. Stand up AI-native workflows for the team.
• Define how we use Claude, Cursor, and the rest of the toolchain — patterns, evals, guardrails, prompts — so AI leverage is a team capability, not a personal habit.
• Keep the foundations healthy. Own the backend and infra well enough to make sure nothing brittle ships and production stays boring.
• CI/CD, deploy hygiene, observability, architecture decisions.
• Set the hiring bar. Be the technical screen and the reason strong candidates say yes.

Requirements

• A track record of using AI to build real products and systems dramatically faster than the old way — with no loss of quality.
• Excellent product judgment. Understand the user, know what to build and what to cut, and 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. Effective in small, high-trust teams with wide scope and ambiguous problems.
• 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. 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.
