Senior Mixed-Signal Post-Silicon Validation Engineer

The role

This person will bring up and characterize complex mixed-signal SoCs from first silicon through product integration. They will work with analog/mixed-signal designers, systems/DSP, firmware, FPGA, digital, and hardware teams to validate silicon performance and build test and validation capability.

What you will do

• 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.

Required 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 re
• 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.

Nice to have

• RF/mmWave mixed-signal SoC experience.
• Experience with high-speed or RF-sampling ADCs and DACs.
• Experience validating digitally assisted analog circuits and calibration algorithms.
• Familiarity with JESD204 or other high-speed converter interfaces.
• Experience with automated PVT characterization and large-scale measurement data analysis.
• Familiarity with FPGA-based test platforms and embedded firmware.
• SI/PI, package, high-speed PCB, and RF measurement experience.

Benefits

• paid time off
• medical/dental/vision/ coverage
• life insurance
• paid parental leave
• many other perks

Before you apply

• Must be a U.S. person as defined by 22 C.F.R. § 120.15 or otherwise eligible for a federally issued export control license.
• The person hired will have access to information and items controlled by U.S. export control regulations, including ITAR.
