What you need

You have operated high-stakes systems. You have 5-7+ years of full-stack engineering experience. You've built and operated production systems that handle real complexity, crossing the boundary between complex backend domain logic and polished frontend user experiences.
You master client-side state and performance. You know how to manage complex state across a large frontend application. You understand the tradeoffs of server-side rendering vs. client-side fetching, caching strategies, and how to build interfaces that feel instantaneous even when the underlying healthcare APIs are slow.
You get data modeling right. You think carefully about schema design and API boundaries, because you've seen what happens to the frontend when the foundational backend model is wrong.
You are a full lifecycle owner. You build things that run in production, not just pass review. You are comfortable with (or eager to master) Kubernetes, Terraform, AWS, and CI/CD, and you view deploying your own code and owning your system's reliability as a fundamental part of your job.
Your workflows are altered by AI. You are already using frontier agentic tools (e.g., Codex 5.3, Claude Opus 4.6) to build faster. You can describe specific ways these models have structurally changed how you code, while retaining the deep technical skepticism required to audit, verify, and own its output.
You are a collaborative builder. You have low ego, high standards, and excellent communication skills. You thrive in cross-functional environments where engineering requirements are heavily shaped by healthcare regulations, compliance, and patient safety.
You are excited to work in-person. You want to build alongside the team 5 days a week in our San Francisco office.
If you are targeting Staff leveling: We expect a demonstrated track record of setting technical direction across teams, navigating deep ambiguity, and measurably leveling up the engineers around you.

Our Process

We respect your time. Here is exactly what to expect

Intro call (30 min, remote) – Chat with our recruiter about the role and expectations.
Technical round (2 hrs, remote) – Practical coding (AI tools welcome) + system design conversation. Real problems, not LeetCode.
Behavioral interview (45 min, remote) – Technical background, motivation, and what you're looking for.
Team meet (2 hrs on-site) — Come to our SF office to meet your future manager, engineering peers, and product partners for 30-minute 1:1s, concluding with a quick recruiter wrap-up.

We are ready to move as fast as you are. We can go from the first intro to offer in two weeks, or pace the rounds to comfortably fit your current work schedule.
