Sr. Engineer - Analog Validation

Job Title

Sr. Engineer - Analog Validation

Role Summary

Senior engineer responsible for post-silicon validation and characterization of analog and mixed-signal subsystems in ultra-low-power SoCs. Work with design, firmware, verification, ATE, and product teams to validate analog IP from first silicon through production.

Experience Level

Senior — typically requires 5+ years of experience in post-silicon validation, analog characterization, or related semiconductor development.

Responsibilities

Execute validation plans, perform precision measurements and analysis, and debug interactions across analog, digital, firmware, and power subsystems.

• Develop and execute post-silicon validation plans for analog and mixed-signal SoC subsystems.
• Characterize analog IP across process, voltage, temperature, operating modes, and silicon margins.
• Validate blocks such as ADCs, DACs, comparators, oscillators, PLLs, references, sensors, regulators, and power management circuits.
• Develop automated test software, embedded firmware, data logging, analysis, and report-generation tools.
• Perform detailed analysis of accuracy, linearity, noise, offset, gain, timing, stability, frequency response, and power consumption.
• Correlate silicon results with design expectations, simulation, ATE, and production test data.
• Debug complex SoC-level issues involving analog, digital, firmware, clocks, power management, and board hardware.
• Support validation hardware, test board development, lab setup, instrumentation, and characterization infrastructure.
• Collaborate across teams to improve test coverage, yield, and production readiness.

Requirements

Core qualifications and skills required for independent execution of analog validation tasks.

Must-have

• 5+ years of experience in post-silicon validation, analog characterization, mixed-signal validation, or related semiconductor development.
• Strong understanding of analog and mixed-signal circuit behavior and measurement techniques.
• Hands-on experience validating integrated analog blocks such as ADCs, DACs, oscillators, PLLs, references, regulators, or sensor interfaces.
• Experience with lab instrumentation: oscilloscopes, spectrum analyzers, signal generators, precision DMMs, source-measure units, power supplies, and low-current measurement equipment.
• Experience developing automation using Python, Tcl, C/C++ or similar languages.
• Embedded firmware development experience on ARM-based MCU or SoC platforms.
• Strong analytical and troubleshooting skills; able to independently debug complex silicon and system-level issues.
• Authorization to work in the United States; this role does not provide visa sponsorship.

Nice-to-have

• Experience with ultra-low-power SoCs and advanced power management architectures.
• High-resolution ADC characterization, clocking circuits, PLLs, oscillators, and voltage regulation experience.
• PVT characterization, shmoo testing, statistical analysis, and specification limit development.
• Experience correlating bench characterization with ATE and production test results, and familiarity with automated characterization frameworks, Linux, Git, and structured data analysis workflows.
• Noise analysis, signal integrity, and board-level analog design experience.

Education Requirements

Bachelor's or Master's degree in Electrical Engineering or a related field (BS or MS in Electrical Engineering or related technical discipline).
