• Drive best practices in code quality, testing, and CI/CD.
• Collaborate with product and design to deliver exceptional user experiences.
• Shape architecture: Influence patterns, tooling, and platform standards that enable speed with safety.

What we’re looking for:

• Senior-level experience (7+ years) building production-grade web applications end‑to‑end.
• Deep expertise in React - hooks, state management, performance optimisation.
• Strong Node.js/Express skills, including API design, security, scalability, and maintainability.
• Proven ability to solve complex problems independently and deliver production-ready solutions.
• Pragmatic problem solver: You are biased toward action, communicate clearly, and thrive with autonomy.
• Bonus: Experience with Firebase, GCP, healthcare tech.

How we work:

• Small, senior teams: High trust, high ownership, minimal ceremony.
• Customer-first: We iterate quickly and measure outcomes, not just output.
• Secure by design: We build with privacy and safety in mind, given the sensitivity of health data.

Our stack:

React, Node/Express, GCP, Firebase.
