You will work on software that supports both proprietary and standards‑based wireless systems, contributing to technology used across a broad range of IoT applications.

• Design, develop, and maintain embedded software for Silicon Labs low‑power wireless MCUs and SDKs
• Own software features from requirements and design through implementation, validation, release, and long‑term support
• Build and enhance low‑level firmware components such as device drivers, initialization and startup code, timing‑sensitive system software, and radio control features
• Optimize software for performance, reliability, power efficiency, and memory/CPU utilization in real‑time embedded environments
• Debug complex issues across software, firmware, hardware, and system boundaries using lab tools and debuggers
• Collaborate with hardware, silicon, systems, and product teams to define requirements, review designs, and support bring‑up of new devices
• Contribute to automated test, validation, and development tooling to improve product quality and engineering efficiency
• Participate in code reviews, design reviews, and technical discussions that raise engineering quality across the team
• Mentor and support other engineers through technical guidance, collaboration, and best practices

• BS or MS in Electrical Engineering, Computer Engineering, Computer Science, or a related field, or equivalent practical experience
• 5+ years of professional experience in embedded software or firmware development
• Strong programming skills in Embedded C and/or C++
• Experience developing software for microcontrollers in resource‑constrained, real‑time environments, including bare metal and/or RTOS‑based systems
• Strong debugging skills at the hardware/software boundary, with hands‑on experience using tools such as debuggers, JTAG/SWD, oscilloscopes, or logic analyzers
• Experience working on low‑level embedded software such as device drivers, interrupts, peripheral interfaces, timing‑sensitive code, or memory‑constrained systems
• Experience taking features from design through implementation, test, and release
• Experience with artificial intelligence (AI)‑powered tools and technologies used to enhance productivity, analysis, and decision‑making
• Strong problem‑solving, communication, and collaboration skills

• Experience with wireless or connectivity technologies such as Bluetooth LE, Zigbee, Thread, Wi‑Fi, or proprietary radio systems
• Experience with communication stacks, radio control software, PHY/MAC‑related functionality, or other timing‑critical embedded software
• Experience optimizing embedded systems for low power, performance, and reliability
• Experience with common embedded interfaces and peripherals such as SPI, I2C, UART, DMA, timers, and interrupts
• Experience with Python or similar scripting languages for tooling, automation, testing, or build workflows
• Experience with automated test, CI, validation frameworks, or hardware‑in‑the‑loop test environments
• Experience with silicon bring‑up, hardware validation, or close collaboration with chip or board design teams
• Experience with multi‑core microcontrollers, concurrency, synchronization, or shared‑resource challenges
• Familiarity with assembly on ARM, RISC‑V, or similar MCU architectures
• Experience using AI‑assisted development tools (such as Git Hub Copilot, Cursor, ChatGPT, or similar) to support prototyping, test development, debugging, automation, and documentation, with strong engineering judgment and validation practices

• Great medical (Choice of PPO or Consumer Driven Health Plan with HSA)
• Dental & vision plans
• Flexible vacation plan
• Highly competitive salary
• 401(k) plan with match and Roth plan option
• Equity rewards (RSUs)
• Life/AD&D and disability coverage
• Flexible spending accounts
