Bluetooth Developer

Job Description

Key Responsibilities: 1. Bluetooth Protocol Development Design and implement Bluetooth stack functionality (BR/EDR and BLE). Develop low-level drivers for Bluetooth hardware and radio modules. Work with Bluetooth Core protocols (L2CAP, HCI, RFCOMM, etc.). Ensure compatibility with Bluetooth SIG standards. 2. Application Development Develop Bluetooth-based applications for Android , iOS , and embedded platforms . Create and maintain Bluetooth profiles (A2DP, HFP, HID, GATT, etc.). Work on Bluetooth Low Energy (BLE) use cases, including advertising, scanning, and pairing. 3. Connectivity and Performance Optimization Optimize Bluetooth connection stability, range, and throughput. Improve power consumption and latency in Bluetooth communication. Debug and resolve Bluetooth-related issues using tools like Ellisys and Frontline . 4. Testing and Troubleshooting Conduct interoperability testing with third-party Bluetooth devices. Perform stress testing and packet analysis for performance evaluation. Use Bluetooth sniffers and packet analyzers to debug issues. 5. Cross-Team Collaboration Work with hardware, firmware, and software teams to ensure seamless Bluetooth integration. Collaborate with UX/UI teams to ensure user-friendly Bluetooth connectivity. Provide technical guidance to QA teams for Bluetooth feature validation. Required Skills and Experience: 4+ years of experience in Bluetooth development (Classic and BLE). Strong understanding of Bluetooth stack (L2CAP, ATT, HCI, RFCOMM, SDP, etc.). Proficiency in C/C++ , Python , and Java/Kotlin (for Android) or Swift/Objective-C (for iOS). Experience with Bluetooth chipset integration (e.g., Qualcomm, Broadcom, Nordic). Hands-on experience with Bluetooth sniffers (Ellisys, Frontline). Knowledge of Bluetooth profiles (A2DP, HFP, HID, GATT). Strong debugging skills for Bluetooth connection, pairing, and data transfer issues. Experience with embedded systems and low-level hardware interfacing. Preferred Skills: Experience with Bluetooth 5.x (Long Range, LE Audio). Knowledge of RF testing and antenna design principles. Familiarity with Bluetooth SIG certification process. Experience with real-time operating systems (RTOS) and microcontrollers (e.g., ARM Cortex). Understanding of wireless coexistence (Wi-Fi, LTE, NFC).
