Senior SQA Engineer - BR/EDR Profiles/ LE Audio/ Bluetooth Low Energy(BLE) - 5+years of exp

Overview

Senior Wireless QA Engineer on the Wireless QA Team, testing and validating Bluetooth profiles, protocol stack implementations and wireless performance for Silicon Labs products.

What you'll do

• Develop comprehensive test plans, strategies and approaches for Bluetooth testing, covering Bluetooth Classic, BLE, Bluetooth mesh and related protocols.
• Design and execute detailed tests for Bluetooth profiles (e.g., A2DP, HFP, GATT, LE Audio etc), ensuring proper implementation and functionality in real-world scenarios.
• Test and validate Bluetooth protocol stack implementations, including interoperability between different Bluetooth versions, chipsets and operating systems.
• Analyze and troubleshoot complex issues related to Bluetooth communication, signal interference, range and performance.
• Develop and maintain custom test scripts, automated test cases and tools (using languages like Python, Embedded C) for Bluetooth functionality, performance and stress testing.
• Utilize specialized Bluetooth test tools and protocol analyzers (e.g., Ellisys, Teledyne LeCroy) to capture, decode and analyze Bluetooth traffic.
• Conduct performance testing to assess Bluetooth range, data throughput, connection stability and battery consumption, particularly for Bluetooth Low Energy (BLE) devices.
• Test Bluetooth security features, including pairing protocols, encryption and authentication, to identify vulnerabilities and ensure data protection.

What you'll need

• At least 5+ years of experience in software testing/development, with a focus on Bluetooth technology and test automation using Python/Embedded C.
• In-depth knowledge of Bluetooth technologies, including Bluetooth Classic, Bluetooth Low Energy (BLE), Bluetooth mesh, LE Audio and the Bluetooth protocol stack.
• Strong understanding of Bluetooth profiles such as A2DP, HFP, HID, GATT, PAN, LE Audio, and their respective functionalities and use cases.
• Expertise in using Bluetooth testing tools and protocol analyzers (e.g., Ellisys, Teledyne LeCroy, Frontline).
• Experience with Bluetooth specification documentation (e.g., Bluetooth SIG), and familiarity with Bluetooth standards (e.g., Bluetooth 5.x, BLE).
• Experience in LE Audio profiles – BAP, TMAP, CAP and LC3 Codec.
• Strong analytical and troubleshooting skills, particularly in complex Bluetooth connectivity and performance issues.
• Excellent communication skills to collaborate with cross-functional teams, document test results and present findings clearly to stakeholders.

Nice to have
