Job Description

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

• 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.

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.

Qualifications

​​​​​​​ Required Skills

• 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

  • 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.

Preferred Qualifications

• 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
