Job description

The IoT Software Quality Assurance (SQA) Team at Silicon Labs, spread across multiple global locations, focuses on improving the overall quality of the Silicon Labs Gecko SDK. The Gecko SDK includes all wireless protocols (Bluetooth Low Energy (BLE), Bluetooth Mesh, Zigbee, OpenThread, Wi-Sun, Z-Wave, and proprietary protocols) and 32-bit microcontroller (MCU) software required to build IoT products.

Our SQA team works closely with software development teams to ensure a deep understanding of product features and system functionality. We leverage an internal test framework to automate tests for repeatability and stability, providing detailed reports on each build to ensure quality assurance. With decades of experience, our team delivers high-quality embedded software products to some of the biggest names in the industry.

The Role

Silicon Labs is looking for a Software Developer in Test to plan, develop, debug, and automate test scripts to improve the overall quality of the Radio Abstraction Interface Layer (RAIL). This layer abstracts complex radio functionality from networking stacks, enabling faster adoption of each radio platform.

Since all Silicon Labs wireless protocols utilize RAIL, this role is critical to the foundation of our Gecko SDK software product. Most of our customers build IoT products such as smart homes, smart metering, and smart cities.

You will be the primary Software Developer in Test responsible for providing test coverage for RAIL features and maintaining build-to-build quality and consistency. The ideal candidate has experience with radio architectures, PHY layers, embedded software, and firmware for MCU peripherals.

You will collaborate closely with development teams in Boston and Austin, as well as global SQA teams. Proficiency in C, and Python is required.
