Job summary

Teton is seeking an experienced Frontend Engineer to own customer-facing features from first conversations with care teams to production. You’ll work on web, mobile apps and the APIs behind them, shipping features that actually shift how care teams work.

You’ll talk to users, scope work, implement solutions, and help define quality through tests, CI/CD pipelines and guardrails, all while collaborating with designers and product teams across markets.

Qualifications

• Several years of experience building production web applications.
• Strong TypeScript skills.
• Solid production experience with React on the web and/or React Native.
• Experience with CI/CD and automated testing, and a strong sense of what good code quality looks like.
• Great product taste and a keen eye for UX. You work well with designers and can make sensible design decisions yourself when needed.
• Comfortable talking directly with non-technical users and turning messy feedback into concrete decisions.
• Previous startup experience and/or shipping a product where you owned the outcome, from idea to adoption.
• Strong problem-solving skills and the ability to work both independently and in a team.

Responsibilities

• Feature Development: Own features end-to-end, from design discussions through implementation to production rollout across multiple markets and languages, on the web app, the mobile app and the APIs behind them.
• Customer Insight: Talk to care staff and our customer success team every week, visit care facilities, and turn what you hear into clearly scoped product changes.
• Code Quality & Guardrails: Help own code quality across the frontend. Improve our CI/CD pipelines and automated tests, keep the infrastructure scalable, and build the guardrails that let AI coding agents contribute safely.
• Backend & APIs: Work with the APIs, data models and services your features need. You will not just consume APIs, you will help shape, improve and fix the systems behind them.
• Quality, Privacy & Safety: Ship with care for health data: sensible access control, auditability and privacy by default. Use staged rollouts so new features never get in the way of the alerts care teams depend on.
