Senior React Native Engineer

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 to help shape the future of digital therapeutics.

Your Role

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.

Your Responsibilities

• Design, build, and ship high-quality React Native apps for iOS and Android with TypeScript.
• 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.
• Uphold technical excellence in architecture, code quality, and security, especially under healthcare regulations (ISO 62304, TR-03161, 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.
