Summary

Duration: 12-month contract
 
Job Description:
  • We are seeking a senior-level contractor to lead production test development for SoC devices integrating copackaged optics (CPO) SerDes interfaces.
  • This role centers on ATE program development, DFT/BIST enablement, yield/quality optimization, and high-volume manufacturability.
  • Strong understanding of SerDes and protocols such as UCIe and PCIe is required, with emphasis on translating characterization into robust, multisite production tests.
  • Experience with Python-based automation and data analytics is essential; familiarity with AI-assisted tools for test development and data triage is a plus.
 
Responsibilities:
  • Own development, integration, and maintenance of wafer sort and final test programs on ATE for SoC SerDes with copackaged optics.
  • Define and implement production test coverage for SerDes PHY and protocol features (PRBS, loopback, margining, FEC, CDR lock, EQ settings) using on-die BIST/DFT and ATE instrumentation.
  • Implement and optimize multisite strategies, parallel test execution, guardbanding, and test time reduction while meeting quality and coverage goals.
  • Correlate bench/char results to ATE: develop golden-unit flows, establish limits, build characterization-to-production handoff, and close gaps.
  • Integrate DFT features (scan/ATPG, boundary scan, MBIST/LBIST, JTAG) into production flows; manage pattern conversion, timing sets, and pin maps.
  • Implement UCIe/PCIe-related production checks: link training emulation, LTSSM state verification via firmware or test hooks, compliance counters, and error injection/monitoring.
  • Build Python-based tooling for ATE control, data parsing, STDF analytics, dashboards, and automated limit updates; integrate with MES/SPC and CI pipelines.
  • Collaborate with silicon design, firmware, DFT, product engineering, OSAT/probe, and SI teams to resolve issues and qualify ECOs/revisions.
  • Document test plans, specifications, vector maps, limits, and release notes; train operations teams and support sustaining engineering.
 
Experience:
  • Minimum 5 years’ of experience
 
Skillsets:
  • Hands-on experience developing on leading ATE platforms (e.g., Advantest V93K/AC+, Teradyne UltraFLEX/UltraFLEXplus) including timing sets, DC/AC measurements, and multisite.
  • Strong understanding of SerDes/PHY fundamentals: equalization, CDR, CTLE/DFE, PRBS/BER, margining, jitter/eye constraints, and on-die BIST integration.
  • Proficiency in Python for automation and data analytics; experience with STDF parsing, visualization, and automated SPC/anomaly detection.
  • Solid DFT background: scan/ATPG patterns, boundary scan, MBIST/LBIST, JTAG access, pattern formats (WGL/STIL), and pattern bring-up on ATE.
  • Working knowledge of UCIe and PCIe (Gen5/Gen6 preferred) from a production test perspective: link checks via firmware/test hooks, error counters, and compliance indicators.
  • Excellent documentation, cross-functional communication, and problem-solving skills.
 
Education:
  • Under-graduate degree preferred.
