Senior RF Systems Test Engineer — Automation & 5G Validation

GreenWave Radios; San Jose (CA); Hybrid; USD 110,000 - 160,000; Full time

Job summary

InnoPhase Inc., DBA GreenWave Radios, in San Jose, CA, seeks a highly technical Staff RF System Test Engineer to develop, automate, and execute system-level validation for next‑gen RF SoC platforms from early silicon bring‑up through production release.

You will build automated test infrastructure, characterize RF performance, debug complex issues, and translate data into design guidance for cross‑functional teams in RF hardware, embedded software, and test automation.

Qualifications

• BS in Electrical Engineering, Computer Engineering, Computer Science, or related field.
• 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 architectures.
• Hands-on experience with RF test instrumentation including spectrum analyzers, vector signal analyzers/generators, VNAs, oscilloscopes, power meters, and related equipment.
• Experience validating wireless systems operating across multiple radio technologies, including 4G and 5G platforms.

Responsibilities

• Design, implement, and execute 3GPP 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
