Senior RF/mmWave Post-Silicon Validation Engineer

Socket.dev; Los Angeles (CA); On-site; USD 170,000 - 250,000; Full time

Job summary

K2 Space in California is seeking a hands-on RF/mmWave Post-Silicon Validation Engineer to bring up and characterize highly integrated RF and mmWave SoCs from first silicon through product integration.

You will work closely with RFIC designers, systems/DSP, mixed-signal, firmware, hardware, and validation teams to characterize RF performance, validate calibration algorithms, debug complex silicon issues, and build our RF test and validation capability from the ground up.

Qualifications

• 5+ years of RF/mmWave silicon validation and test experience.
• Hands-on RF/mmWave test equipment experience.
• Knowledge of RF transceiver architectures and RF/mmWave circuits.
• Experience with automated characterization environments using Python.
• Strong debugging across silicon, package, PCB and test setups.
• Ability to collaborate with RFIC designers and systems engineers.
• Ability to build RF test capability in a fast-moving environment.

Responsibilities

• Bring up and characterize RF/mmWave silicon, including TX/RX chains, LNAs, PAs, mixers, LO generation, PLLs, and RF front ends.
• Develop and execute RF characterization plans across frequency, power, voltage, temperature, process, and operating modes.
• Measure RF performance including gain, noise figure, output power, compression, linearity, EVM, ACLR, phase noise, spurs, harmonics, and dynamic range.
• Develop automated RF/mmWave test setups for characterization, regression, data collection, analysis, and reporting.
• Collaborate with RFIC designers to correlate silicon measurements with simulations and identify root causes.
• Partner with systems/DSP teams to validate RF calibration and signal-processing algorithms on silicon.
• Debug complex issues spanning silicon, package, PCB, firmware, calibration, and test setups.
• Support transition from chip-level RF characterization to product integration and system-level validation.
• Contribute to building the RF/mmWave validation lab, measurement infrastructure, test methodology, and automation.
• Document characterization results, silicon limitations, workarounds, and lessons learned for future silicon generations.
