* Collaboration: Work closely with our Head of Engineering, Principal Engineer, Product Designer, and CEO.

* Build and ship end‑to‑end features across the Next.js frontend and Node/TypeScript backend.
* Model and tune Postgres schemas; ensure secure authN/authZ and strong performance.
* Integrate external APIs and improve app reliability and speed (including Lighthouse‑driven improvements).

What you will bring
* Proficiency with AI tools to accelerate development and quality.

In your first 90 days, you will:
* Lead at least one significant feature from design to production, used by real clinics or internal teams.
* Improve a key part of the frontend experience (e.g., performance, usability, or design consistency) and document the standards for others.
* Own part of the backend or data model, including at least one meaningful performance or reliability improvement.
* Help define or refine testing and deployment practices so the team can ship faster and with more confidence.
Nice to have
* Experience building voice‑controlled components / speech‑to‑text.
