Post Silicon Hardware Validation Staff Engineer

Job Title

Post Silicon Hardware Validation Staff Engineer

Role Summary

Perform hands-on post-silicon validation and electrical characterization of high-speed mixed-signal memory interface devices. Execute silicon bring-up, electrical measurements, and hardware debugging to identify failure mechanisms and improve silicon performance.

Collaborate with analog, mixed-signal, digital, SI/PI, package, and product engineering teams to drive root-cause analysis and recommend design improvements based on laboratory characterization data.

Experience Level

Senior — requires 8+ years of hands-on laboratory experience validating high-speed semiconductor devices.

Responsibilities

Key responsibilities include silicon bring-up, electrical measurements, debugging, and documentation.

• Execute silicon bring-up and bench validation from first silicon through production release.
• Measure and characterize electrical, timing, jitter, voltage, and signal-integrity parameters.
• Use high-bandwidth oscilloscopes, BERTs, high-speed pattern generators, network and logic analyzers, and precision power supplies.
• Apply measurement techniques such as de-embedding, high-impedance and differential probing, eye-diagram analysis, jitter analysis, and noise characterization.
• Debug issues involving signal integrity, timing margins, power delivery, termination networks, PCB effects, and package interactions.
• Correlate bench measurements with simulation and design expectations and recommend design improvements.
• Develop repeatable validation methodologies, document test setups and results, and present findings to engineering teams.

Requirements

Must-have skills and experience for this role.

• 8+ years of hands-on laboratory experience validating high-speed semiconductor devices.
• Strong background in high-speed analog and mixed-signal circuits, hardware validation, silicon characterization, and post-silicon validation.
• Extensive experience with oscilloscopes (20 GHz+ preferred), BERT systems, high-speed probing, signal-integrity measurements, compliance testing, eye-diagram and jitter analysis.
• Strong understanding of transmission lines, reflection and termination, crosstalk, equalization, power integrity, and high-speed PCB design fundamentals.
• Experience debugging hardware at the board, package, and silicon level; strong analytical and troubleshooting skills in a laboratory environment.
• Excellent written and verbal communication skills; ability to present technical findings to design and executive teams.
• Familiarity with scripting/automation tools (Python, MATLAB, LabVIEW) for test execution and data processing — used to automate measurements, not for software development.

Education Requirements

Bachelor's or Master's degree in Electrical Engineering or Computer Engineering. A Master's degree in Electrical Engineering is preferred.
