Post Silicon Hardware Validation Staff Engineer

We are seeking an experienced hardware validation & characterization engineer to characterize and validate next-generation high-speed memory interface silicon. This role is highly hands-on and laboratory focused, requiring extensive experience with electrical measurements, silicon bring-up, signal integrity, and debugging of high-speed mixed-signal devices.

The ideal candidate enjoys solving difficult hardware problems using advanced laboratory equipment and possesses a deep understanding of high-speed electrical interfaces rather than software development.

Hardware Validation & Characterization

Design Collaboration

- Work directly with Analog, Mixed-Signal, Digital, SI/PI, Package, and Product Engineering teams.
- Support root-cause analysis of silicon issues discovered during validation.
- Drive hardware-based debug using systematic electrical measurements rather than software-only analysis.
- Recommend design improvements based on laboratory characterization data.

Data Analysis & Documentation

- Analyze characterization results to identify failure mechanisms and performance trends.
- Develop repeatable validation methodologies and characterization procedures.
- Document test methods, hardware setups, measurement assumptions, and validation results.
- Present technical findings to design, product, and executive engineering teams.

Note: Python or similar scripting languages are used primarily for automating test execution and processing measurement data—not for software development.
