From the original posting
K2 is building the largest and highest-power satellites ever flown, unlocking performance levels previously out of reach across every orbit. Backed by over $1 billion in total funding from leading investors including Altimeter Capital, ICONIQ, Kleiner Perkins, Lightspeed Venture Partners, Redpoint Ventures, and T. Rowe Price — and with over $1 billion in signed contracts across commercial and US government customers, we're mass-producing the highest-power satellite platforms ever built for missions from LEO to deep space.
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
