## Job Description

## What You'll Do

- Build High-Density Healthcare Interfaces: Architect dynamic, multi-step medical intake engines, high-density provider charting dashboards, and patient-facing apps that handle sensitive PHI with perfect state synchronization.
- Bridge Clinical & Client: Connect complex backend medication ordering and fulfillment pipelines to intuitive, highly responsive frontend interfaces. Translate dense healthcare requirements into seamless digital experiences.
- Champion the User Experience: Sweat the details of the UI and make pragmatic, high-quality design decisions on the fly that measurably improve patient outcomes.
- Own the Full Lifecycle: Design the database schema, write the API, build the React interface, deploy the service, and own both backend reliability and client-side error tracking in production.
- Build Agentic Workflows: Integrate AI capabilities directly into our product to automate clinical operations and scale our provider workflows. Utilize frontier agentic models to accelerate your own development.
- Raise the Engineering Bar: Own key architectural decisions across the stack, systematically upgrade legacy code, and elevate the engineers around you through rigorous code review, testing practices, and technical standards.

## Who You Are

- 5-7+ years of full-stack engineering experience building and operating production systems that handle real complexity, crossing the boundary between complex backend domain logic and polished frontend user experiences.
- Master client-side state and performance: Manage complex state across a large frontend application. Understand tradeoffs of server-side rendering vs. client-side fetching, caching strategies, and building interfaces that feel instantaneous.
- Strong data modeling skills: Think carefully about schema design and API boundaries.
- Full lifecycle owner: Comfortable with (or eager to master) Kubernetes, Terraform, AWS, and CI/CD. View deploying your own code and owning your system's reliability as fundamental.
- AI-altered workflows: Already using frontier agentic tools (e.g., Codex, Claude) to build faster, with the technical skepticism to audit, verify, and own its output.
- Collaborative builder with low ego, high standards, and excellent communication skills. Thrive in cross-functional environments shaped by healthcare regulations, compliance, and patient safety.
- Excited to work in-person 5 days a week in our San Francisco office.

**For Staff leveling:** Demonstrated track record of setting technical direction across teams, navigating deep ambiguity, and measurably leveling up the engineers around you.
