Full Job Description
We are seeking a Wi-Fi Test Engineer to validate the performance, stability, and interoperability of our Wi-Fi IoT chipsets. This role focuses on hands-on chipset testing, automated test development, performance analysis, and close collaboration with firmware and hardware teams to improve product quality and reliability.
Key Responsibilities:
• Perform Wi-Fi chipset functional, performance, and stability testing on evaluation boards and embedded platforms.
• Design and execute Rate vs. Range (RvR), TCP/UDP throughput, receiver sensitivity, and long-duration stability tests under different RF and network conditions.
• Conduct interoperability testing with access points, routers, and client devices from multiple vendors.
• Develop, maintain, and optimize Python test scripts and automated regression frameworks.
• Set up and maintain test benches with programmable attenuators, RF instruments, access points, and other equipment.
• Analyze logs, packet captures, and performance metrics; identify regressions, reproduce failures, and support root-cause analysis.
• Summarize test results, track performance trends, and deliver clear technical reports and recommendations.
• Collaborate with firmware, PHY/MAC, and RF engineers to validate new features, verify fixes, and support releases.
Job Requirements:
• Bachelor's degree or higher in Electrical Engineering, Computer Engineering, Computer Science, Telecommunications, or a related field.
• 3+ years of Wi-Fi chipset, module, embedded-system, or wireless-product testing experience.
• Good understanding of IEEE 802.11n/ac/ax; familiarity with 802.11be is preferred.
• Hands-on experience with Wi-Fi RvR, throughput, stability, and interoperability testing.
• Strong Python scripting skills and experience with automated testing frameworks.
• Familiarity with iperf/iperf3, Wireshark, programmable RF attenuators, and RF test equipment.
• Ability to analyze test data, diagnose failures, and produce organized technical reports.
• Familiarity with Linux command-line tools and embedded-system debugging.
• Strong problem-solving, communication, and cross-functional collaboration skills.
Strong Plus
• Experience with Espressif ESP32 / ESP-IDF Wi-Fi development, testing, or debugging.
• Experience with Wi-Fi Alliance (WFA) certification and associated test tools.
• Experience using CMW500, IQxel, spectrum analyzers, or signal generators.
• Knowledge of MIMO, OFDMA, beamforming, power save, and rate adaptation.
• Experience with Bluetooth/BLE and Wi-Fi/Bluetooth coexistence testing.
• Experience building automated RvR test benches or CI-based hardware regression systems.
