Principal Test Engineer

Job Overview:
The Principal Test Engineer is responsible for owning ATE test enablement, first-silicon bring-up, characterization, and production release for complex SoCs on Advantest 93K. This role drives manufacturing test execution across wafer sort, final test, SLT, OSAT release, and HVM, with strong emphasis on test architecture, SmarTest 8, Advantest 93K hardware, HSIO methodology, functional test, structural test integration, ATE hardware readiness, and scalable production execution.
This role requires 12+ years of experience in semiconductor manufacturing and test, with deep hands-on expertise in Advantest 93K, SmarTest 7 / SmarTest 8, test program development, HSIO test/debug, ATE characterization, pattern conversion, test method development, binning strategy, and cross-functional execution with Design, DFT, Product Engineering, vendors, third-party teams, and OSATs.
Responsibilities:

• Own test enablement for upcoming silicon projects, including ATE strategy, Advantest 93K hardware configuration, SmarTest 8 program structure, test flow development, debug visibility, datalogging, and manufacturing readiness.
• Drive first-silicon bring-up on ATE, including daily progress reporting, issue triage, silicon/ATE debug, characterization execution, correlation, and handoff from engineering bring-up to CP, FT, SLT, OSAT, and HVM release.
• Define and implement ATE characterization plans across voltage, frequency, temperature, process, functional content, HSIO margins, structural coverage, binning strategy, guardbands, and production limits.
• Develop and maintain ATE test methods, flows, revision-control framework, pattern conversion infrastructure, and production test content for functional, HSIO, ATPG/Scan, MBIST, PHY BIST, DC, leakage, IDDQ, and other manufacturing test types.
• Guide ATE test hardware development with vendors and OSATs, including wafer probe card, load board, socket, thermal control interface, tester resources, HSIO connectivity, signal integrity, power delivery, and active thermal management.
• Work with Design, DFT, Firmware, Product Engineering, third-party contractors, offshore teams, ATE suppliers, and OSATs to debug complex issues, improve test quality, close coverage gaps, and deliver production-ready test solutions on schedule.

Required Skills and Experience :

• 12+ years of experience in semiconductor manufacturing, ATE test development, product engineering, silicon bring-up, characterization, or production release for complex SoCs, CPUs, AI accelerators, chiplet-based devices, or advanced semiconductor products.
• Expert hands-on knowledge of Advantest 93K ATE test program development, including SmarTest 7 / SmarTest 8, tester hardware, digital patterns, test methods, test flow development, datalogging, debug flows, binning, revision control, and production integration.
• Strong experience in test architecture and HSIO test/debug, including PCIe, UCIe, DDR, SerDes, PHY BIST, protocol-based test, IO topology, bench-to-ATE correlation, oscilloscopes, BERTs, emulation, simulation, and production margining.
• Working understanding of functional testing, structural test integration, DFT concepts, PHY BIST, silicon fabrication process, packaging, product qualification, manufacturing steps, and HVM release requirements.
• Experience owning end-to-end project execution from architecture through first silicon, bring-up, characterization, CP/FT deployment, OSAT release, production ramp, yield debug, and continuous improvement.
• Strong ability to work across Design, DFT, Firmware, Product Engineering, vendors, OSATs, third-party teams, and customers, with proven debug capability across silicon, ATE hardware, SmarTest software, patterns, firmware, package/board design, HSIO IP, and manufacturing flows.
