Job summary

K2 Space is seeking 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 designers, systems/DSP, firmware, FPGA, digital, and hardware teams to validate silicon performance and build validation capability from the ground up.

The role involves developing automated characterization environments, executing plans across temperature and

Qualifications

• BS/MS in Electrical Engineering or related field.
• 5+ years of mixed-signal silicon validation or related experience.
• Strong understanding of ADC, DAC, PLL, clocking, and analog circuit fundamentals.
• Hands-on experience with high-speed lab equipment (O-Scope, spectrum/signal analyzers, VSGs, phase-noise analyzers, VNAs).
• Experience automating characterization environments using Python or similar scripting languages.
• 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 (SNDR, SFDR, ENOB, INL/DNL, noise, bandwidth, jitter, phase noise, linearity, power).
• Develop automated test setups for characterization, regression, data collection, analysis, and reporting.
• Collaborate with IC designers and systems engineers to correlate measurements with simulations and models.
• Support transition from chip-level validation to product integration and system-level testing.
• Document characterization results, limitations, workarounds, and lessons learned for future generations.
