Job summary

K2 Space seeks 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, collaborating with analog/mixed-signal designers, DSP/firmware, FPGA, and hardware teams to validate performance.

You will develop and execute characterization plans across frequency, voltage, and temperature, measure SNDR, SFDR, ENOB, INL/DNL, noise, bandwidth and jitter, and build automated test setups and

Qualifications

• 5+ years of mixed-signal silicon validation or related experience.
• Strong knowledge of ADC, DAC, PLL, clocking and analog fundamentals.
• Hands-on with high-speed test equipment (oscilloscopes, spectrum analyzers, VNAs, phase-noise analyzers, network analyzers, power supplies).
• Experience automating characterization environments using Python.
• Ability to correlate measurements with simulations and models.

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.
