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/I²C 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 (Wi‑Fi/Bluetooth) and lab tools (oscilloscope, logic analyzer, power meter).
  • Familiarity with open Bluetooth ecosystems (e.g., Zephyr/NimBLE).

It is key to unleash the potential in every employee, every team, every leader, and the company herself. We know employees perform best when motivated, appreciated and recognized, and can be themselves. We are committed to building a culture where every voice can be heard, everyone has room for growth and can make meaningful contributions. At the end of the day, we want success not just for the company, but also for everyone who believes in the company, the vision, and the future.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
