Senior Embedded Software Engineer - IoT Wireless Applications
Boston, MA
 

Silicon Labs is looking for a Senior Embedded Software Engineer - IoT Wireless Applications - to join our Boston-based RAIL team.

In this role, you will help develop foundational embedded software that enables customers to build reliable, power-efficient wireless products on Silicon Labs devices. 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.
 

This is a great opportunity for an experienced embedded engineer who enjoys working close to the hardware, solving complex technical problems, and owning software from concept through release. While experience in wireless systems is a plus, we are also excited to hear from candidates with strong embedded systems fundamentals who want to grow deeper in wireless applications.
 

Meet the Team 

The RAIL team develops the Radio Abstraction Interface Layer (RAIL) SDK, a common radio software platform that helps customers build wireless applications without needing to master device-specific radio details. Our work enables everything from low-power battery-operated devices to more complex multi-protocol systems.

As part of this team, you will collaborate closely with firmware, silicon, systems, and test engineers to deliver high-quality embedded software that helps customers build innovative connected products.
 

Responsibilities

As a Senior Embedded Software Engineer on the RAIL team, you will:

• 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

Skills You Will Need  

Minimum Qualifications:  

• 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

The following qualifications will be considered as a plus:  

• 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 GitHub Copilot, Cursor, ChatGPT, or similar) to support prototyping, test development, debugging, automation, and documentation, with strong engineering judgment and validation practices
   

Why Join Silicon Labs

• Work on foundational wireless technology used across a wide range of IoT products
• Solve interesting technical problems at the intersection of embedded software, hardware, and wireless systems
• Collaborate with experienced engineers across firmware, silicon, systems, and test
• Make a direct impact on technology that helps customers bring connected products to market faster
• Continue growing your technical depth in embedded systems and wireless applications
