The Bluetooth R&D team at Silicon Labs develops and maintains embedded firmware for wireless products across Bluetooth Classic and Bluetooth Low Energy (BLE).

The team works on performance-critical, standards-compliant firmware enabling advanced use cases such as audio streaming, HFP calling, and LE Audio, in close collaboration with cross-functional engineering teams across multiple global locations.

The Role :

Silicon Labs is seeking a Senior Software Engineer - Embedded Firmware to design and deliver high-quality embedded firmware for resource-constrained wireless systems.

This is a hands-on, embedded-centric role requiring deep expertise in real-time firmware development, low-level debugging, and system-level thinking.

Bluetooth experience-particularly in audio-related use cases-is strongly preferred, but the role primarily targets engineers with proven senior-level embedded firmware skills who can quickly ramp on complex wireless stacks and drive technical ownership.

Key Responsibilities :

- Design, implement, and maintain real-time embedded firmware in C/C++ for resource-constrained system.

- Own complex firmware features from design through implementation, debugging, and release.

- Develop timing-critical, performance-sensitive code with strong attention to memory, power, and CPU constraint.

- Debug complex system-level issues spanning firmware, hardware, and protocol interaction.

- Contribute to multi-protocol and wireless coexistence (CoEx) solution.

- Participate in technical design reviews, code reviews, and product qualification activities.

- Collaborate closely with cross-functional teams including systems, PHY/RF, validation, and customer-facing engineering team.

- Provide technical mentorship and guidance to junior engineers and contribute to team knowledge sharing.

Required Skills and Experience :

- Strong, hands-on experience in embedded firmware development, with deep proficiency in C/C++.

- Solid understanding of real-time systems, interrupts, concurrency, and low-level hardware interaction.

- Proven experience building memory- and power-optimized embedded software.

- Strong debugging skills using hardware and software tools (JTAG, trace, logs, protocol analyzers, etc.).

- Experience delivering embedded software products from concept through production.

Preferred / Bonus Skills :

- Experience with Bluetooth Classic and/or Bluetooth Low Energy (BLE).

- Familiarity with Bluetooth audio use cases (e.g., A2DP, HFP, LE Audio).

- Understanding of Bluetooth controller architectures and wireless protocol stacks.

- Experience with wireless coexistence (CoEx) and multi-protocol systems.

- Familiarity with modern development workflows, including automation, scripting, and CI practices.

- Exposure to or practical use of GenAI-assisted development tools (e.g., GitHub Copilot, ChatGPT).

Education and Experience :

- Bachelors or Masters degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field, or equivalent practical experience.

- 5 to 10 years of industry experience in embedded firmware or systems-level software development.

Benefits & Perks :

Not only will you be joining a highly skilled and tight-knit team where every engineer makes a significant impact on the product; we also strive for good work/life balance and to make our environment welcoming and fun.
