• Design, develop, and maintain Bluetooth Classic & BLE features. • Implement and debug A2DP audio streaming, pairing, reconnect, and role switching. • Work across Android Bluetooth stack (Fluoride/BlueZ where applicable), HAL, and vendor layers. • Optimize latency, stability, power, and coexistence (BT/Wi-Fi). • Debug complex issues using btmon, hcidump, snoop logs, adb, logcat. • Integrate profiles: A2DP, HFP/HSP, AVRCP, PBAP, SPP, GATT. • Handle production scenarios: auto-reconnect, long-run stability, suspend/resume. • Android auto exposure is good to have • Support CTS/VTS and release readiness. • Knowledge on LE audio is desirable. Requirements • Strong Bluetooth Classic & BLE fundamentals. • Hands-on A2DP implementation/debugging. • Android platform or embedded Linux experience. • Solid debugging and ownership mindset.
