Headquartered in San Diego, California, Green Wave Radios™ has established itself as a pioneer in delivering power-efficient digital-to-RF solutions. The company is supported by a talented team of over 100 engineers spread across four global R&D facilities. With an extensive portfolio of more than 120 global patents, Green Wave Radios™ continues to push the boundaries of radio technology and innovation.

Green Wave Radios is seeking a highly technical Staff RF System Test Engineer to develop, automate, and execute system-level validation of next-generation RF SoC platforms from early silicon bring-up through production release. You will be a hands‑on contributor responsible for uncovering complex RF performance issues, building scalable test infrastructure, and generating the data that drives critical design decisions.

As a member of the Systems Engineering Group in San Jose, CA, this role sits at the intersection of RF hardware, embedded software, and test automation. You will work directly with designers and developers to characterize radio performance, debug challenging system behaviors, and create robust automated test solutions that ensure compliance with global wireless standards.

The ideal candidate combines deep RF measurement expertise with strong software development skills and enjoys solving difficult technical problems through rigorous experimentation and data-driven analysis.

• Design, implement, and execute 3
  
  GPP Radio Conformance Testing (RCT) methodologies for next-generation RF SoC and radio platforms, including test development, automation, data analysis, and debug
• Develop automated validation frameworks, instrument drivers, and measurement applications in Python and MATLAB to improve test coverage, repeatability, and engineering productivity
• Perform hands‑on characterization of RF subsystems and signal chains, including power amplifiers (PA), low‑noise amplifiers (LNA), filters, CFR, and DPD algorithms across multiple wireless technologies and carrier configurations
• Investigate and root-cause RF performance issues using laboratory measurements, statistical analysis, and cross‑functional debugging with hardware, firmware, and software teams
• Develop custom measurement techniques and validation workflows to evaluate key radio performance metrics such as EVM, ACLR, sensitivity, Noise Figure, spectral emissions, and transmitter linearity
• Drive silicon bring‑up and system‑level validation activities, identify performance gaps, and provide actionable recommendations to design teams
• Evaluate, integrate, and optimize advanced RF test equipment and commercial test solutions to improve measurement accuracy and test throughput
• Build scalable automated regression test environments that support continuous validation throughout the product lifecycle
• Analyze large RF data sets to identify trends, anomalies, and performance limitations, translating results into clear technical insights and design guidance
• Author detailed technical reports, validation procedures, and engineering documentation that support product development, certification, and manufacturing readiness

• BS in Electrical Engineering, Computer Engineering, Computer Science, or related field required; MS preferred
• 8+ years of hands‑on RF system test, validation, or characterization experience with wireless communication products
• Strong software development skills in Python and MATLAB with demonstrated experience building automated test infrastructure and measurement tools
• Deep understanding of RF measurement principles and wireless performance metrics, including EVM, ACLR, spectral emissions, sensitivity, Noise Figure, gain, linearity, and transmitter performance
• Proven experience characterizing and debugging RF subsystems such as CFR, DPD, PA, LNA, filters, mixers, and transceiver…
