About The Position

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. This role is not a software development, firmware, embedded software, machine learning, or data science position. Candidates with demonstrated experience in post-silicon validation, component characterization, electrical engineering laboratories, high-speed memory interfaces, signal integrity, and mixed-signal hardware debugging will be highly preferred.

Requirements

• Bachelor’s or Master’s degree in Electrical Engineering or Computer Engineering.
• 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, Silicon bring-up, Post-silicon validation.
• Extensive experience with: Oscilloscopes (20GHz+ preferred), BERT systems, High-speed probing, Signal integrity measurements, Compliance testing, Eye diagram analysis, Jitter measurements.
• Strong understanding of: Signal integrity, Transmission lines, Reflection and termination, Crosstalk, Equalization, Power integrity, 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.

Nice To Haves

• Master’s degree in Electrical Engineering.
• Experience with DDR5, DDR4, LPDDR5, MRDIMM, RDIMM, or memory buffer devices.
• Experience validating: Memory PHYs, High-speed SerDes, PCIe, USB, Ethernet, Other multi-Gbps interfaces.
• Familiarity with: IBIS-AMI, HyperLynx, ADS, HFSS, Sigrity, Cadence SI tools.
• Experience correlating silicon measurements to simulation models.
• Python, MATLAB, or LabVIEW for test automation and data processing.

Responsibilities

• Perform bench validation and electrical characterization of high-speed mixed-signal memory interface devices.
• Execute silicon bring-up and hardware debugging from first silicon through production release.
• Measure and characterize critical electrical, timing, jitter, voltage, and signal integrity parameters.
• Utilize advanced laboratory instrumentation including: High-bandwidth oscilloscopes, BERTs (Bit Error Rate Testers), High-speed pattern generators, Network analyzers, Logic analyzers, High-precision power supplies.
• Apply advanced measurement techniques including: De-embedding, High-impedance probing, Differential probing, Eye diagram analysis, Jitter analysis, Noise characterization.
• Debug complex hardware issues involving signal integrity, timing margins, power delivery, termination networks, PCB effects, and package interactions.
• Correlate bench measurements with simulation and design expectations to improve silicon performance.
• 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.
• 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.
