Senior Mobile App Engineer (React Native)
Posted Updated
- As a Senior Mobile App Engineer, you’ll help power Beacon’s mission by building the cross-platform React Native apps that patients and clinicians use with our EEG headbands and other wearables
- Your work will shape how people capture high-fidelity data and how easily they move through clinical trials and at-home diagnostics
- This isn’t just another app. You’ll build tools that help unlock insights into neurological, psychiatric, and sleep disorders, with the potential to improve lives at scale
- What success looks like:
- As part of our small, mission-driven Mobile Apps Team, you will:
- Lead development of our React Native mobile applications across iOS and Android
- Design and implement UX workflows for clinical trial participants and at-home diagnostic patients
- Own the user experience, performance, reliability, and observability of the apps and features you build, using feedback from real users across diverse use cases and environments
- Work with engineers on our native iOS and Android BLE device SDKs to integrate device capabilities cleanly into the app
- Partner with our Devices team, other Platform teams, and product designers to build user-centric mobile capabilities deeply integrated with the rest of Beacon’s product ecosystem
- Help shape the roadmap and technical direction of our mobile platform
- In your first 3–6 months, you might:
- Build a new in-app feature to validate EEG signal quality before data capture
- Streamline onboarding for new patients and trial participants to make our devices easier to use than ever
- Deploy new features that help our Clinical Operations team track compliance
- Improve app performance, release reliability, and crash/telemetry visibility across our Expo-based build pipeline
- Strong communication skills and comfort working in a collaborative, async environment
- Strong TypeScript skills and familiarity with our stack (React Native, Expo, GitHub)
- Experience with app state management, offline-first data handling, and app store release processes
- A product mindset: you care deeply about UX, edge cases, and performance
- 8+ years of experience in mobile development, including substantial experience shipping and maintaining production React Native apps on both iOS and Android
- Integrated BLE peripheral devices into iOS and/or Android applications, or worked with sensor integration or health data streams
- Worked on apps for clinical trials, patients, or another regulated environment
- Written native code (Swift or Kotlin) or built native modules for React Native
- Worked with medical devices, EEG, or wearables
- Contributed to open source mobile or React Native projects
