About Us

At Teton, we are redefining the role of healthcare workers through cutting‑edge AI technology. In the face of a global nursing shortage, our solutions provide vital support to overburdened health systems.

With thousands of residents and patient rooms across 4 countries and 2 continents already benefiting from our technology, we are rapidly expanding our reach. What sets us apart is our relentless focus on product excellence and user experience, deploying solutions at speed that make a tangible difference in patient care. Specifically we are reducing falls (+40%), reaction time (+96%), tracking sleep, respiration and more, building a general health understanding of the people we monitor, resulting in improved health outcomes for people.

The position requires a physical presence at our office in Copenhagen, Denmark. If you are looking for a 9‑17 job, perform best with structure and struggle dealing with unknowns, this is not for you. We believe close collaboration between a hard‑working, high‑agency team enables the fastest and most efficient iteration cycles, helping us build an impactful product that healthcare professionals truly love to use.

The Job

We’re looking for a talented and driven Software Engineer to join our Mobile team building the tools that healthcare 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.

In this role, you will focus on:

• 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 hospital environments with unreliable Wi‑Fi.
• Backend & Infrastructure: Work with PostgreSQL, Express.js, and AWS to support the systems our app depends on. You won’t just consume APIs—you’ll help shape and fix 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.

Qualifications

• 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.

What We Offer

• Participation in our warrant program (stock options).
• A small, senior team where your decisions directly shape the product.
• A Copenhagen‑based office with close collaboration—no async‑only culture.
• Work on software that healthcare workers depend on every day— the impact is tangible and immediate.

Join Our Team

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.
