Lead Engineer - SW Design

About the Team
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 systems.

• 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 constraints.

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

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

• 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 teams.

• 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 interactions.

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

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

• Demonstrated ability to independently drive technical solutions and make sound design decisions.

• 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., audio streaming, 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., AI code assistants, analysis tools, productivity tools) as a productivity and quality enhancement.

Education and Experience
Bachelor’s or Master’s 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.

"Experience with artificial intelligence (AI) powered tools and technologies used to enhance productivity, analysis, and decision-making"
