The Role

Silicon Labs is looking for a Software (SW) Developer in Test to plan, develop, debug embedded applications, and automate test scripts to improve the overall quality of different wireless protocol SDKs. Protocol SDK implements a standard API over the protocol stack (for example: Bluetooth Low Energy, Bluetooth-MESH, Proprietary, etc...) and peripherals, allows quicker customer application development. Each Silicon Labs wireless protocol is integrated into the Silicon Labs Gecko SDK. Most of our customers are focused on building Internet of Things (IoT) products (smart homes, smart metering, smart cities). You will be the primary SW Developer in Test responsible for providing test coverage on each SDK feature as well as maintain build-to-build quality and consistency. It would be a plus if you would have experience working with embedded SW and Firmware used to control MCU peripherals. You will frequently interact with the SW Development Team based in Budapest, Espoo, Rennes, and Boston.

The Silicon Labs SQA team is a tight group of software professionals, with a broad understanding of Continuous Integration testing initiatives in wireless networks and a passion for innovation, quality, and providing business value through technology. We care about the business we support and take pride in the technology services we deliver and go the extra mile to “Do the Right Thing” for Silicon Labs and its customers. Members of our team appreciate that we are greater than the sum of our parts.

The IoT SQA Team's Responsibilities

The IoT Software Quality Assurance (SQA) Team at Silicon Labs which is spread across several different geographical locations, focuses on improving the overall quality of the Silicon Labs Gecko SDK Product. The Gecko SDK products contain all the wireless (Bluetooth Low Energy (BLE), Bluetooth Mesh, Zigbee, OpenThread, Wi-SUN, Z-Wave, and proprietary protocols) and 32-bit microcontroller (MCU) software required to build end products for the Internet of Things (IoT) Market. Silicon Lab’s SQA Team works closely with the Software (SW) Development teams to ensure a deep understanding of the product, features, and system functionality. Silicon Lab’s SQA Team utilizes an internal test framework to automate all tests for repeatability and stability along with providing detailed test reports on each build of the product to provide our customers with quality assurance. The SQA team has decades of experience in providing high-quality embedded SW products to our customers which include the largest names in the industry.
