Lead Engineer - SW Design

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"

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.
