As we expand our product portfolio and modernize our platform, we’re looking for a versatile, pragmatic, and forward-thinking (Senior) React Native Engineer (m/f/x) to help shape the future of digital therapeutics.\nYour Role\nYou’ll join a cross-functional product team with high ownership, lean processes, and a clear focus: deliver real impact to patients. We’re looking for someone who thrives on solving real-world problems with code, is technology-open, and knows when to build fast and when to build right. You’ll also help us use AI tools and coding agents thoughtfully in day-to-day engineering, turning emerging capabilities into reliable workflows that improve how we design, build, test, and operate patient-facing products.\nYour Responsibilities\nDesign, build, and ship high-quality React Native apps for iOS and Android with TypeScript.\nUse AI coding agents to implement features, refactor code, and generate tests. Define clear tasks and constraints, provide relevant context, and validate the resulting changes through code review, automated tests, and checks on real devices.\nOwn the full mobile lifecycle: architecture, implementation, automated testing, release management, monitoring, and iteration.\nIntegrate native capabilities (push notifications, deep links, biometric auth, camera/sensors); write and maintain native modules when needed (Swift/Kotlin).\nDrive mobile performance and reliability (startup time, bundle size, memory, battery) and meet accessibility best practices.\nSet up and evolve mobile CI/CD (e.g., Fastlane, GitHub Actions/Bitrise), internal testing (TestFlight/Play Console), and release pipelines.\nCollaborate closely with Product, Design, and Medical to explore, define, and deliver patient-centric features, and to improve our current platform.\nConnectAI-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.\nUphold technical excellence in architecture, code quality, and security, especially in a regulated healthcare environment, including applicable requirements under IEC 62304, BSI TR-03161, and the MDR.\nContribute to a platform that powers multiple regulated digital health products across indications like IBS, GERD, and upcoming expansions.\nMentor other developers and help raise the technical bar across the team.\nRequirements\nYour Profile\n5+ years of professional software engineering experience, with at least 3 years focused on React Native and shipping production apps.\nExpert with React Native and TypeScript, React Navigation, state management, and testing (Jest, React Native Testing Library; Detox a plus).\nHands-on experience using AI coding agents to implement features, refactor code, and write automated tests, including connecting agents to engineering tools via MCP. You can explain how you scoped the work, verified the results, and handled tool permissions and sensitive data.\nProven track record delivering to App Store and Google Play, including handling certificates/provisioning, in-app updates, and staged rollouts.\nSolid understanding of mobile security and privacy: secure storage, keychain/keystore, certificate pinning, data minimization, and PII handling.\nExperience with mobile CI/CD and release automation (Fastlane, GitHub Actions or Bitrise), and tools like Sentry.\nProduct mindset: you’ve worked in product-centric teams, collaborated closely with non-technical stakeholders, and care deeply about UX and accessibility.\n Bonus: experience in regulated industries, healthcare, or other security-conscious environments; native iOS/Android development (Swift/Kotlin)\nPlease note: Cara Care is a remote-first company with a fully distributed team. All team members are based in Germany so candidates must reside in Germany to join us.\nBenefits\nFair compensation: We offer fair pay, regular salary reviews, and the equipment you need to do your best work.\nGreat team spirit: Join a vibrant, interdisciplinary team and enjoy a friendly, supportive working atmosphere, with regular in-person team events.\nRemote-first working: Prefer working from home? No problem. Want to join us at our Berlin office? That works too. Our remote-first approach gives you the flexibility to work where it suits you best.\n30 days off per year: Rest matters. You’ll get 26 vacation days plus 4 additional company-wide mental health days each year to take a breather and recharge.\nFlexible working hours: Whether you’re an early bird or prefer a later start, you can shape your working day around what works for you.\nUrban Sports Club (USC): Enjoy access to a wide range of sports, fitness, and wellness activities at discounted rates.\nOpenUp: Access a variety of resources and services to support your mental health and personal wellbeing.\nCorporate Benefits: Get attractive discounts and exclusive offers from a wide range of well-known brands and providers.\nMake a real impact: Be involved, contribute your ideas, and help shape what comes next. Your voice matters, and you can make a real difference.\nAbout Cara Care\nCara Care is a digital health company on a mission to improve the lives of people with digestive health conditions through holistic, science-based digital therapies.\nOur established IBS therapy, Cara Care für Reizdarm, provides personalised content, practical exercises, and symptom tracking to help people better understand and manage their condition.
