What you'll do
- Design, build, and ship high-quality React Native apps for iOS and Android with TypeScript
- Use AI coding agents to implement features, refactor code, and generate tests; define clear tasks and constraints, provide relevant context, and validate resulting changes through code review, automated tests, and checks on real devices
- Own the full mobile lifecycle: architecture, implementation, automated testing, release management, monitoring, and iteration
- Integrate native capabilities (push notifications, deep links, biometric auth, camera/sensors); write and maintain native modules when needed (Swift/Kotlin)
- Drive mobile performance and reliability (startup time, bundle size, memory, battery) and meet accessibility best practices
- Set up and evolve mobile CI/CD (e.g., Fastlane, GitHub Actions/Bitrise), internal testing (TestFlight/Play Console), and release pipelines
- Collaborate closely with Product, Design, and Medical to explore, define, and deliver patient-centric features, and to improve the current platform
- Connect AI-assisted development workflows to design and engineering tools via MCP, for example to access Figma specifications and components, check implementations against designs, and automate repetitive coding and validation tasks; keep patient data, credentials, and other sensitive information out of unapproved tools and workflows
- Uphold technical excellence in architecture, code quality, and security in a regulated healthcare environment, including applicable requirements under IEC 62304, BSI TR-03161, and the MDR
- Contribute to a platform that powers multiple regulated digital health products across indications like IBS, GERD, and upcoming expansions
- Mentor other developers and help raise the technical bar across the team
What we're looking for
- 5+ years of professional software engineering experience, with at least 3 years focused on React Native and shipping production apps
- Expert with React Native and TypeScript, React Navigation, state management, and testing (Jest, React Native Testing Library; Detox a plus)
- Hands-on experience using AI coding agents to implement features, refactor code, and write automated tests, including connecting agents to engineering tools via MCP; able to explain how work was scoped, results verified, and tool permissions and sensitive data handled
- Proven track record delivering to App Store and Google Play, including handling certificates/provisioning, in-app updates, and staged rollouts
- Solid understanding of mobile security and privacy: secure storage, keychain/keystore, certificate pinning, data minimization, and PII handling
- Experience with mobile CI/CD and release automation (Fastlane, GitHub Actions or Bitrise), and tools like Sentry
- Product mindset: worked in product-centric teams, collaborated closely with non-technical stakeholders, and cares deeply about UX and accessibility
- Candidates must reside in Germany
Nice to have
- Experience in regulated industries, healthcare, or other security-conscious environments
- Native iOS/Android development (Swift/Kotlin)
Benefits
Great team spirit: vibrant, interdisciplinary team and a friendly, supportive working atmosphere, with regular in-person team events
- Fair compensation: fair pay, regular salary reviews, and the equipment needed to do your best work
- Remote-first working: flexibility to work from home or join at the Berlin office
- 30 days off per year: 26 vacation days plus 4 additional company-wide mental health days each year
- Flexible working hours
- Urban Sports Club (USC): access to a wide range of sports, fitness, and wellness activities at discounted rates
- OpenUp: resources and services to support mental health and personal wellbeing
- Corporate Benefits: attractive discounts and exclusive offers from a wide range of well-known brands and providers
