Job summary

K2 Space in Seattle, WA seeks 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 capability from the ground up.

Qualifications

• BS/MS in Electrical Engineering or related field.
• 5+ years of RF/mmWave silicon validation, characterization, RFIC test, or related experience.
• Strong understanding of RF transceiver architectures and RF/mmWave circuits, including LNAs, PAs, mixers, PLLs, and frequency-generation systems.
• Deep hands-on experience with RF/mmWave test equipment (vector network analyzers, spectrum analyzers, vector signal generators, oscilloscopes, power meters, noise-figure analyzers, phase-noise measurement equipment).
• Experience developing automated characterization environments using Python or similar scripting languages and instrument-control interfaces.
• Strong debugging skills across silicon, package, PCB, firmware, and measurement environments.

Responsibilities

• Bring up and characterize RF/mmWave silicon, including TX/RX signal 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, spurious, harmonics, sensitivity, 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 gaps.
• Partner with systems/DSP teams to validate RF calibration and signal-processing algorithms on silicon.
• Debug issues spanning silicon, package, PCB, firmware, calibration, test setup, and system behavior.
• Support transition from chip-level RF characterization to product integration and system-level validation.
• Contribute to building RF/mmWave validation lab, measurement infrastructure, test methodology, and automation from ground up.
• Document characterization results, silicon limitations, workarounds, and lessons learned for future generations.
