About the role

Hands-on senior role to bring up, characterize, and validate highly integrated RF and mmWave SoCs from first silicon through product integration. Collaborates with RFIC, systems/DSP, mixed-signal, firmware, hardware, and validation teams to characterize RF performance, validate calibration algorithms, debug silicon issues, and build RF test/validation capability from the ground up.

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 key RF performance including gain, noise figure, output power, compression, linearity, EVM, ACLR, phase noise, spurious performance, harmonics, sensitivity, and dynamic range.
  • Develop automated RF/mmWave test setups for characterization, regression, data collection, analysis, and reporting.
  • Work closely with RFIC designers to correlate silicon measurements with simulations and identify performance gaps and root causes.
  • Partner with systems/DSP teams to validate RF calibration and signal-processing algorithms on silicon and correlate performance with system models.
  • Debug complex issues spanning silicon, package, PCB, firmware, calibration, test setup, and system behavior.
  • Support the 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 from the ground up.
  • Document characterization results, silicon limitations, workarounds, and lessons learned for future silicon generations.

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 including vector network analyzers, spectrum/signal analyzers, vector signal generators, oscilloscopes, power meters, noise-figure analyzers, and phase-noise measurement equipment.
  • Strong understanding of RF measurement techniques, calibration, de-embedding, noise, linearity, modulation quality, and spectral analysis.
  • Experience developing automated characterization environments using Python or similar scripting languages and instrument-control interfaces.
  • Strong debugging skills and ability to isolate problems across silicon, package, PCB, firmware, and measurement environments.
  • Experience working closely with RFIC designers and systems engineers to correlate measurements with circuit simulations and system models.
  • Ability to operate effectively in a fast-moving environment and build RF test capability from the ground up.

Benefits

  • Base salary range for this role is $170,000 – $250,000 + equity in the company
  • Salary will be based on several factors including, but not limited to: knowledge and skills, education, and experience level
  • Comprehensive benefits package including paid time off, medical/dental/vision/coverage, life insurance, paid parental leave, and many other perks
