About the role

Hands-on senior role to bring up and characterize complex mixed-signal SoCs from first silicon through product integration, collaborating with analog/mixed-signal, systems/DSP, firmware, FPGA, digital, and hardware teams to validate silicon performance, debug issues, and build validation capability from the ground up.

Responsibilities

  • Bring up and characterize mixed-signal silicon, including ADCs, DACs, PLLs, clocking, references, power, and analog signal paths.
  • Develop and execute characterization plans across frequency, voltage, temperature, process, and operating modes.
  • Measure key converter and analog performance including SNDR, SFDR, ENOB, INL/DNL, noise, bandwidth, jitter, phase noise, linearity, and power.
  • Develop automated test setups for characterization, regression, data collection, analysis, and reporting.
  • Work closely with analog/mixed-signal designers to correlate silicon measurements with simulations and identify performance gaps.
  • Partner with systems/DSP teams to validate DSP and calibration algorithms on silicon and correlate results with system models.
  • Debug complex issues spanning silicon, firmware, package, PCB, test setup, and system behavior.
  • Support the transition from chip-level validation to product integration and system-level testing.
  • Contribute to building the validation lab, test infrastructure, measurement 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 mixed-signal silicon validation, characterization, product engineering, or related experience.
  • Strong understanding of ADC, DAC, PLL, clocking, and analog circuit fundamentals.
  • Deep hands-on experience with lab test equipment such as high-speed oscilloscopes, spectrum/signal analyzers, vector signal generators, phase-noise analyzers, network analyzers, power supplies, and related mixed-signal instrumentation.
  • Experience developing automated characterization environments using Python or similar scripting languages and instrument-control interfaces.
  • Strong understanding of signal integrity, noise, clock jitter, spectral analysis, and mixed-signal measurement techniques.
  • Strong debugging skills and ability to isolate issues across chip, package, PCB, firmware, and test environments.
  • Experience working closely with IC designers and systems engineers to correlate measurements with simulations and models.
  • Ability to operate effectively in a fast-moving environment and build test capability from the ground up.
