Bluetooth Firmware Engineer

Role Summary

Design, implement, and ship Bluetooth Controller firmware across BLE (Link Layer/MAC) and Bluetooth Classic (BR/EDR LM behaviors) on our SoCs. Work spans bring-up, timing & reliability, test/qualification, and cross-functional debug with RF, systems, and QA-hands-on from lab benches to release.

Key Responsibilities

• Firmware development (Controller): Implement and maintain controller features aligned to Bluetooth Core Spec 5.x and 6.x for BLE and Bluetooth Classic.
• Bring-up & stabilization: Bring up features on FPGA/eval boards/silicon; tune timing/latency paths in RTOS environments for BLE and Classic.
• Test & qualification support: support certification/interop; analyze sniffer/HCI logs and close issues with clear root cause.
• System-level debugging: Triage issues across firmware, drivers, and basic RF interactions; collaborate with Hardware/RF, Systems, and QA to land fixes.
• Tooling & automation: Contribute HCI test scripts, utilities, and CI checks that improve repeatability and coverage.
• Maintenance: Participate in code reviews, documentation, and sustaining engineering for released features.

Core Competencies

• Hands-on experience in Bluetooth controller firmware with understanding of BLE LL/MAC and Bluetooth Classic LM procedures.
• Strong embedded C skills (interrupts, memory-safe coding, RTOS concurrency).
• Comfort with UART/SPI/IC and board bring-up workflows.
• Ability to work with sniffer/HCI logs (BLE and Classic) and embedded debuggers; strong analytical and troubleshooting ability.
• Organized, detail-oriented, proactive, and effective in cross-functional teams.
• Clear written and verbal communication.

Qualifications (Requirements)

• E./B.Tech/M.E./M.Tech in ECE/EE/CS (or equivalent practical experience).
• 5-9 years of embedded firmware experience on MCUs/SoCs with RTOS.
• Proficiency in C, version control, code reviews, and CI basics.
• Experience developing to Bluetooth Core Spec 5.x and 6.x at the controller level-covering BLE LL/MAC and exposure to Bluetooth Classic BR/EDR LM procedures.
• Exposure to system test, troubleshooting, and root-cause analysis of Bluetooth products.
• Basic RF awareness.
• Coexistence basics (WiFi/Bluetooth) and lab tools (oscilloscope, logic analyzer, power meter).
• Familiarity with open Bluetooth ecosystems (e.g., Zephyr/NimBLE).
