About the role
Key Responsibilities: Bluetooth Stack Integration Integrate and configure Bluetooth stack (Classic & BLE) into infotainment platforms (QNX, Android Automotive, Linux). Enable and customize Bluetooth profiles (HFP, A2DP, AVRCP, PBAP, MAP, SPP, GATT, HID) according to OEM requirements. Collaborate with chipset vendors (Qualcomm, NXP, Renesas) to adapt BSP and HAL layers for Bluetooth functionality. Development & Debugging Analyze Bluetooth logs (HCI traces, BT snoop logs, stack logs) and resolve connectivity, audio streaming, and telephony issues. Debug protocol-level issues (pairing, bonding, encryption, authentication). Implement fixes and optimizations in middleware, service layers, or adaptation modules. Work with Audio/DSP teams to integrate BT audio (SCO/eSCO, A2DP) paths with infotainment pipelines. System Integration Ensure smooth coexistence of Bluetooth with Wi-Fi, LTE/5G, and GNSS modules. Integrate Bluetooth features with applications such as Android Auto, Apple CarPlay, Alexa Auto, and OEM-specific apps. Support OTA update mechanisms for Bluetooth features and ensure backward compatibility. Required Skills & Qualifications: Strong understanding of Bluetooth Core specifications (v4.2, v5.0 and above). Hands-on experience with Bluetooth profiles: HFP, A2DP/AVRCP, PBAP, MAP, GATT, HID. Proficiency with Bluetooth protocol analyzers (Ellisys, Frontline, Teledyne LeCroy). Familiarity with Android Bluedroid/Fluoride stack, QNX BT stack, or Linux BlueZ. Debugging tools: logcat, adb, QXDM, QCAT, Wireshark. Audio path integration knowledge: SCO/eSCO, LC3 codec, ACDB/DSP routing.
