Role summary
Seeking a Senior Wi-Fi Test Engineer to perform exploratory and performance testing on Wi-Fi features across CPE devices like gateways, routers, and extenders. Responsibilities include validating Wi-Fi functionality (SSID, security, steering, roaming), testing real-world scenarios (dense clients, interference), identifying edge cases, and analyzing logs/packet captures. The role requires strong understanding of Wi-Fi fundamentals (802.11 standards, frequency bands), hands-on experience with broadband devices and embedded Linux systems, and familiarity with testing tools like iPerf and Wireshark. Collaboration with development and product teams is key.
