Key Responsibilities
Design and execute Wi-Fi test cases to evaluate product RF and protocol-level performance, focusing on factors that directly impact user experience (e.g., throughput, latency, stability, and roaming).
Operate RF and protocol testing instruments, such as spectrum analyzers, signal generators, OTA (over-the-air) chambers for antenna performance, and Wi-Fi sniffers for protocol analysis.
Analyze test results, identify performance gaps, and collaborate with hardware, software, and system engineering teams to drive improvements.
Document and present findings in a clear and structured way, providing actionable recommendations for product optimization.
Perform Wi-Fi RF compliance testing in accordance with China regulatory standards to ensure products meet certification requirements.
Contribute to the continuous improvement of test methodologies, workflows, and automation frameworks (e.g., Python-based test scripts).
Qualifications
Bachelor’s or Master’s degree in Electrical Engineering, Communications, Computer Science, or a related field.
3+ years of experience in Wi-Fi testing, RF measurement, or protocol performance evaluation (5+ years preferred).
Hands-on experience with RF test equipment (spectrum analyzer, signal generator, OTA chamber) and performance tools (e.g., IxChariot, iPerf, Wireshark for traffic and packet analysis).
Solid understanding of Wi-Fi standards (IEEE 802.11a/b/g/n/ac/ax/be) and wireless communication fundamentals (RF, OTA, Antenna technologies).
Strong problem-solving skills with the ability to translate technical findings into actionable improvements.
Good communication skills in English, with the ability to collaborate effectively across teams.
Experience with wireless regulatory compliance testing (e.g., SRRC, FCC, CE) or automation scripting (Python, Shell, or similar) is a plus.
