• A rigorous approach to reliability: you care about edge cases, device fragmentation, and performance.
• Strong communication skills and comfort working in a collaborative, async environment.
• Built production React Native apps, or written native modules for React Native or Expo.
• Worked with TypeScript and our broader stack (React Native, Expo, GitHub).
• Worked with medical devices, EEG, or wearables.
• Worked on apps for clinical trials, patients, or another regulated environment.
• Contributed to open source mobile or BLE projects.

Responsibilities

• Lead development of our native iOS and Android BLE device SDKs.
• Own connection reliability, data throughput, and battery performance for device communication across a wide range of phones, OS versions, and real-world environments.
• Partner closely with our Devices team on firmware interfaces, GATT profiles, and device behavior.
• Expose device capabilities to our React Native applications through clean, well-tested native modules.
• Own the observability of device connectivity, using telemetry and field feedback from real users to find and fix failure modes.
• Help shape the roadmap and technical direction of our mobile platform.
• Improve BLE pairing and reconnection reliability across both iOS and Android.
• Increase streaming robustness for EEG data, including recovery from dropped connections and backgrounding.
• Build the device-side support for a new in-app feature that validates EEG signal quality before data capture.
• Add diagnostics that help our Clinical Operations team troubleshoot device issues in the field.
