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.
