About the role

We are seeking a Senior Validation & Characterization Engineer to lead silicon validation and characterization efforts for advanced mixed-signal products. This role involves close collaboration with design, systems, and product test teams to ensure robust, production-ready solutions.

Responsibilities

  • Lead silicon validation and characterization for mixed-signal ICs from first silicon through production release.
  • Define validation strategies, test plans, and coverage for complex analog, digital, and mixed-signal blocks.
  • Design and develop automated validation test environments using lab instrumentation and PXI-based systems.
  • Develop and maintain software frameworks and scripts for validation, characterization, and regression testing (Python preferred).
  • Design silicon validation boards; review schematics and layouts prior to fabrication.
  • Perform detailed data analysis to evaluate performance, margin, robustness, and corner conditions.
  • Collaborate closely with IC design, systems, product test, applications, and reliability teams to debug silicon issues and drive root-cause analysis.
  • Support correlation between validation, characterization, and production test, helping define test limits and guardbands.
  • Contribute to continuous improvement of validation methodologies, documentation practices, and lab efficiency.
  • Communicate results clearly through documentation, presentations, and cross-functional design reviews.
  • Provide technical leadership and mentorship to junior engineers.

Requirements

  • BS in Electrical or Computer Engineering with 5+ years of relevant industry experience.
  • Strong hands-on experience with silicon validation, characterization, or post-silicon debug of mixed-signal ICs.
  • Solid understanding of mixed-signal circuit blocks such as ADCs, DACs, PLLs, amplifiers, regulators, and sensors.
  • Experience developing automated test software and scripts (Python preferred).
  • Familiarity with lab and PXI-based instrumentation (NI PXIe, oscilloscopes, signal generators, audio analyzers, etc.).
  • Experience analyzing large datasets and presenting results using tools such as Excel, JMP, or Spotfire.
  • Strong problem-solving skills with the ability to debug complex hardware/software interactions.
  • Excellent communication skills and experience working cross-functionally with design and test teams.

Qualifications

  • Experience with audio or power-management IC validation.
  • Familiarity with digital communication protocols (I2C, SPI, I2S, TDM, SPMI).
  • Experience correlating validation results with production test coverage.
  • Exposure to embedded firmware or lab automation platforms.
  • Experience mentoring junior engineers or acting as a technical lead on projects.
