About The Position

Discover a world of innovation as an Associate Staff Embedded Software Engineer at Silicon Labs - Boston. The RAIL team develops the Radio Abstraction Interface Layer (RAIL) SDK, which provides an intuitive and customizable radio interface designed to support both proprietary and standards-based wireless protocols. Customers leverage our unified radio software API to efficiently create wireless applications without needing to master device-specific details. This allows for the development of innovative IoT-based wireless devices, ranging from low-power battery-operated applications to complex multi-protocol system. Learn more about the IoT solutions you will work on and our company culture on Glassdoor.

Requirements

BS/MS in EE/ECE/CS (or similar), or equivalent practical experience.
9+ years of professional experience in embedded software/firmware development.
Excellent Embedded C programming skills, including low-level and performance-sensitive code.
Strong understanding of debugging strategies and deep hands-on experience with hardware/software debug tools (e.g., Ozone, J-Link tooling, breakpoints/watchpoints, SWD/JTAG, trace when available).
Experience in resource-constrained, real-time embedded environments (bare metal and/or RTOS).
Solid Python skills for tooling, automation, testing, or build/integration workflows.
Demonstrated ability to take ownership: drive ambiguous problems to closure, communicate status/risks, and make pragmatic technical decisions.
Experience working through the full SDLC: design, implementation, unit/integration testing, CI-style validation, and release.
Experience with artificial intelligence (AI) powered tools and technologies used to enhance productivity, analysis, and decision-making.

Nice To Haves

Experience with wireless protocols such as Bluetooth (BLE), Zigbee, Thread, or Wi-Fi.
Experience developing or debugging wireless PHY/MAC functionality and timing-critical code.
Experience with multi-core microcontrollers and concurrency challenges (inter-core communication, shared resources, interrupt architecture, synchronization).
Assembly proficiency for at least one MCU family (ARM/RISC-V, etc.).
Experience influencing hardware requirements and providing feedback to silicon/hardware design teams.
Experience with test-driven development (TDD) and building robust automated test frameworks.
Familiarity with hardware description languages (HDL) or working knowledge of digital design interfaces.
Demonstrated effective use of AI-assisted development tools (e.g., Cursor, GitHub Copilot, ChatGPT, or similar) to improve productivity and quality—such as accelerating prototyping, writing tests, improving code readability, automating repetitive tasks, summarizing/debugging logs, and supporting documentation/design reviews—while applying sound engineering judgment and secure coding practices.

Responsibilities

Own and deliver embedded software features from concept to release: requirements, design, implementation, verification, documentation, and sustainment.
Design, implement, and maintain the common radio abstraction layer (RAIL) for Silicon Labs low-power wireless MCUs.
Develop and optimize radio PHY and MAC-layer software, including timing-critical and resource-constrained components.
Build and maintain system startup, low-level peripheral drivers, security-related modules, and system test/verification programs.
Drive debug and root-cause analysis of complex issues across software, firmware, and hardware boundaries using advanced techniques and tools (e.g., Segger Ozone and other debuggers, trace, logic analyzers).
Tune code for performance, reliability, memory/CPU utilization, and energy efficiency in real-time embedded environments.
Collaborate with chip design teams to specify hardware requirements, review designs, and validate new silicon bring-up.
Mentor junior engineers through code reviews, design reviews, and best-practice guidance; help elevate engineering rigor across the team.
