About the Role: As a
Principal DDR5 / LPDDR5 PHY Validation Engineer, you will apply extensive, specialized expertise and visionary leadership to strategically deliver high-quality, next-gen memory subsystem validation for AI-integrated processors. This pivotal role leads to significant, unique technical challenges, requiring incisive evaluation of complex data and intangible factors. You will spearhead DDR5 / LPDDR5 PHY-focused validation and signal-quality root-cause efforts assuring exemplary performance and absolute data/stability consistency.
What You'll Achieve: - Own DDR5 / LPDDR5 PHY-focused validation strategy across bring-up, tuning, and release readiness.
- Lead DDR5 / LPDDR5 training/tuning validation and optimization (read/write leveling, timing alignment, Vref, ODT/termination, training convergence).
- Drive signal-quality analysis and root-cause using eye/margin/jitter/clocking and correlation to BER/error rate.
- Build and extend DDR5 / LPDDR5 validation automation and debug tooling using C for execution, logging, sweeps, and data reduction.
- Provide principal-level technical leadership through complex debug ownership, engineering mentoring, and evidence-based reporting/recommendations.
About You: - 6+ years of DDR5 / LPDDR5 PHY expertise in bring-up validation, training/tuning , and stability issue resolution.
- Solid background in DDR5 / LPDDR5 Compliance testing.
- Strong oscilloscope-based debug skills using eye, jitter, clock, and data observations.
- Deep knowledge of how SI/PI impacts DDR5 / LPDDR5 behavior and link stability.
- Competence in analog characterization and turning measurements into clear go/no-go performance decisions.
- C Programming and Python proficiency to build automation and debug tools for validation flows.
- Additional skills highly desired: JEDEC
Education: - BS degree in Electrical Engineering, Computer Engineering, or Computer Science & 8 years of related experience; MS degree & 6 years
