About the Role

We are looking for a hands-on Senior Mixed-Signal Post-Silicon Validation Engineer to bring up and characterize complex mixed-signal SoCs from first silicon through product integration.

You will work closely with analog/mixed-signal designers, systems/DSP, firmware, FPGA, digital, and hardware teams to validate silicon performance, debug issues, and build our test and 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.

Preferred Qualifications

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.

Compensation and 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
