teton - Software Engineer (Mobile) - London
Requirements
• Strong TypeScript skills - this is the language for everything we build. • Solid experience with React Native and Expo in production. • Comfortable working across the stack: you've touched databases, queues, or cloud infra not just UI. • Experience with native iOS or Android development (Kotlin/Swift) is a strong plus we occasionally need to go below the managed Expo layer. • Familiar with real-time systems, push notifications, or TanStack is a plus. • AWS or equivalent cloud platform experience. • Previous startup experience and/or shipping a product where you owned the outcome. • Strong problem-solving skills and ability to work both independently and in a team.
Responsibilities
• We're looking for a talented and driven Software Engineer to join our Mobile team building the tools that care workers rely on during every shift. Our app runs 24/7 in care facilities delivering real-time alerts and monitoring residents. This isn't a typical app dev role. You'll work across the full stack, from React Native UI to backend infrastructure, in an environment where reliability directly impacts patient safety. • Feature Development: Own features end-to-end from design discussions through implementation to production rollout across multiple markets and languages. • Reliability & Debugging: Keep our real-time alert pipeline rock-solid. Debug push notification delivery on Android and iOS, investigate ANR issues, troubleshoot weird bugs in care environments with unreliable Wi-Fi. • Backend, Infrastructure & Systems: Work across backend services, databases, cloud infrastructure, and internal platforms to support the systems our app depends on. You will not just consume APIs, you will help shape, improve, and fix the systems behind them. • Testing & Validation: Build automated test coverage (e.g. Maestro for E2E) across a range of devices and OS versions. Validate that alerts arrive when they must. • Developer Experience: Improve shared components, internal tooling, and build pipelines so the team ships faster with fewer surprises.
Benefits
• Participation in our warrant program (stock options). • A small team where your decisions directly shape the product. • Work on software that healthcare workers depend on every day, the impact is tangible and immediate. • We're looking for individuals who share our vision and value ownership and entrepreneurship over a conventional job. • At Teton, you'll have the chance to make a real impact with your work. • If you're ready for more than just a job, come aboard and be part of our mission to transform healthcare.
