The Role : 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 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
