[Hiring] (Senior) React Native Engineer @Cara Care

Role Description

Cara Care, a digital health company backed by Bayer AG, is on a mission to improve people’s digestive health through technology. 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.

You’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.

Responsibilities

• 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 the 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 our current platform.
• Connect AI-assisted development workflows to design and engineering tools via MCP.
• Uphold technical excellence in architecture, code quality, and security, especially in a regulated healthcare environment.
• 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.

Qualifications

• 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.
• 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: you’ve worked in product-centric teams, collaborated closely with non-technical stakeholders, and care deeply about UX and accessibility.
• Bonus: experience in regulated industries, healthcare, or other security-conscious environments; native iOS/Android development (Swift/Kotlin).

Benefits

• Fair compensation: We offer fair pay, regular salary reviews, and the equipment you need to do your best work.
• Great team spirit: Join a vibrant, interdisciplinary team and enjoy a friendly, supportive working atmosphere, with regular in-person team events.
• Remote-first working: Prefer working from home? No problem. Want to join us at our Berlin office? That works too.
• 30 days off per year: You’ll get 26 vacation days plus 4 additional company-wide mental health days each year.
• Flexible working hours: Shape your working day around what works for you.
• Urban Sports Club (USC): Enjoy access to a wide range of sports, fitness, and wellness activities at discounted rates.
• OpenUp: Access a variety of resources and services to support your mental health and personal wellbeing.
• Corporate Benefits: Get attractive discounts and exclusive offers from a wide range of well-known brands and providers.
• Make a real impact: Be involved, contribute your ideas, and help shape what comes next.
