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.

    • It is key to unleash the potential in every employee, every team, every leader, and the company herself. We know employees perform best when motivated, appreciated and recognized, and can be themselves. We are committed to building a culture where every voice can be heard, everyone has room for growth and can make meaningful contributions. At the end of the day, we want success not just for the company, but also for everyone who believes in the company, the vision, and the future.
