Job summary

K2 Space Corporation in Los Angeles 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.

You will collaborate with analog/mixed-signal, systems, firmware, FPGA, digital and hardware teams to validate silicon performance, debug issues, and build our test and validation capability from the ground up.

Qualifications

• 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 (high-speed oscilloscopes, spectrum/signal analyzers, vector signal generators, phase-noise analyzers, network analyzers, power supplies).
• Experience developing automated characterization environments using Python or similar scripting languages and instrument-control interfaces.
• Strong debugging skills and ability to isolate issues across chip, package, PCB, firmware, and test environments.

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.
• Partner with systems/DSP teams to validate DSP and calibration algorithms on silicon.
• 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.
