About the role

Senior Semiconductor Product Engineering leader to drive manufacturing test strategy and silicon production readiness for next-generation AI accelerator devices, leading internal product engineering teams and external partners across test development, characterization, yield optimization, and high-volume ramp.

Responsibilities

  • Drive the manufacturing test strategy for an AI accelerator chip featuring PCIe Gen6, LPDDR, advanced CMOS nodes, and advanced packaging (e.g., 2.5D/3D, chiplet)
  • Lead and manage a team of chip product engineers responsible for test planning, test program development, pattern bring-up, silicon characterization, debug, and optimization
  • Manage subcontracted test development partners (OSATs, ATE vendors, external engineering services). Includes scoping, technical oversight, schedule tracking, and quality control of deliverables
  • Define and drive test software architecture, DFT usage, and test pattern development strategies for high-speed logic, SRAM, DRAM, and High Speed IO blocks
  • Work closely with design, DFT, manufacturing engineering, packaging, and validation teams to ensure robust test coverage, manufacturability, and yield ramp success
  • Oversee test development for high speed interfaces such as PCIe Gen6 and multi-GHz LPDDR
  • Guide development of structural and functional test content (scan, MBIST, JTAG, HSIO tests, system-level tests)
  • Lead silicon bring-up and development on ATE: correlation, failure analysis, shmooing, corner testing, stress testing, and yield improvement activities
  • Define KPIs and metrics for subcontractor performance, test coverage, yield, time-to-test, and cost optimization
  • Drive continuous improvement in test methodologies, automation, data analytics, and debug infrastructure
  • Ensure robust test flows for advanced packaging (thermals, interposer/bridge connections, TSV integrity, die-to-die IO testing)
  • Support qualification, reliability testing, and high-volume manufacturing transfer

Qualifications

  • BS/MS/PhD in Electronics and Electrical Engineering or related field
  • 8+ years in semiconductor test engineering, including leadership or technical lead roles
  • Experience with ATE test development (e.g., Advantest 93K, Teradyne Ultraflex or similar)
  • Strong understanding of DFT (scan, ATPG, LBIST, MBIST), memory testing, and high-speed interface testing
  • Experience managing external test development partners or OSATs
  • Proven ability to lead and mentor test engineering teams
  • Solid background in advanced CMOS nodes and familiarity with advanced packaging test challenges
  • Expertise in silicon debug, characterization, and correlation across ATE and system-level environments
  • Ability to collaborate across design, architecture, product engineering, packaging, and operations
