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 support for hardware features through the entire IC lifecycle (design, pre-silicon verification, post-silicon verification, 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
7+ 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
Strong problem-solving, communication, and collaboration skills
Nice to Have (Preferred Qualifications):
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 with artificial intelligence (AI) powered tools and technologies used to enhance productivity, analysis, and decision-making
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
