Role
Who you are
- 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
- 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)
- 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)
What the job involves
- 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
- You’ll join a cross-functional product team with high ownership, lean processes, and a clear focus: deliver real impact to patients
- 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
Our take
Cara Care, a subsidiary of HiDoc Technologies, provides a companion app for those living with gut health issues such as IBS, IBD, GERD (heartburn / reflux), and indigestion. Research out of the University of Gothenburg estimates that around 40% of adults worldwide are dealing with gastrointestinal issues, highlighting the scale of the problem that Cara Care is attempting to alleviate.
The German startup’s app is growing in popularity and is well-funded, but it isn’t the only one tapping into the increasingly widespread awareness of gut health issues. ZOE and DayTwo have entered into the field with tens of millions in funding, while bootstrapped company Bowelle is also proving popular.
However, Cara Care’s blend of food and symptom diary with remote telehealth care from certified nutritionists helps set it apart. Crucially, many of its nutritionists are covered by existing insurance policies, while the company is also making a big play for employers, who would provide access to a huge network of users. An acquisition by global health group Bayer in 2024 will implement the commercialisation of the Cara Care app, allowing for wider adoption on a global scale.
