Collaborate with firmware teams to define BLE services, GATT profiles, and communication protocols and to integrate health and wellness features such as heart rate, SpO₂, sleep, activity, and stress monitoring.
Optimize SDK performance, battery consumption, memory usage, and connection reliability.
Create developer documentation, sample applications, integration guides, and debugging tools.
Lead technical discussions and mentor junior engineers.

Familiarity with REST APIs, WebSockets, and cloud-connected applications.
Experience debugging BLE communication using tools such as nRF Connect, Wireshark, or protocol analyzers.
Strong understanding of software design principles, multithreading, and performance optimization.
Experience working on smartwatch, smart ring, fitness tracker, hearable, or other wearable products.
Experience implementing OTA firmware update workflows.
Familiarity with Apple HealthKit, Health Connect integrations, and health data synchronization.
Understanding of sensor technologies including PPG, IMU, temperature, and bio-sensing systems.
