Job summary

InnoPhase Inc., doing business as GreenWave Radios, is seeking a highly technical Staff RF System Engineer in San Jose, CA to develop, automate, and execute system-level validation of next‑generation RF SoC platforms from early silicon bring‑up through production release.

You will work at the intersection of RF hardware, embedded software, and test automation, collaborating with designers and developers to characterize radio performance, debug complex behaviors, and build robust automated test

Qualifications

• BS in Electrical Engineering, Computer Engineering, or Computer Science required; MS preferred.
• 8+ years of hands-on RF system test, validation, or characterization experience.
• Strong software development skills in Python and MATLAB.
• Deep understanding of RF measurement principles and performance metrics.
• Experience with RF test instrumentation such as spectrum analyzers and VNAs.

Responsibilities

• Design, implement, and execute 3GPP Radio Conformance Testing 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
