Semiconductor Test Engineer

Responsibilities

• Develop and maintain ATE test programs for an AI accelerator chip targeting high-volume manufacturing
• Implement manufacturing test content for advanced CMOS designs including high-speed logic, SRAM, DRAM, and high speed IO blocks
• Develop and debug structural and functional test content such as scan/ATPG, LBIST, MBIST, JTAG, and HSIO tests
• Bring up first silicon on ATE, including pattern debug, tester correlation, shmooing, and corner analysis
• Support testing of high-speed interfaces such as PCIe Gen6 and multi-GHz LPDDR
• Execute silicon characterization and failure analysis to identify yield limiters and defect mechanisms
• Optimize test coverage, test time, and cost while maintaining manufacturing robustness
• Work with DFT and design teams to improve testability and close coverage gaps
• Collaborate with OSATs and external partners on test program execution and debug
• Support advanced packaging test flows, including die-to-die interconnect testing
• Support qualification, reliability testing, and high-volume manufacturing ramp

Requirements

• 5+ years of hands-on semiconductor test engineering experience
• Strong experience developing ATE test programs (Advantest 93K, Teradyne, or equivalent)
• Solid understanding of DFT methodologies (scan, ATPG, MBIST, LBIST) and memory test techniques
• Experience debugging silicon issues at the tester and correlating failures to design or process causes
• Familiarity with advanced CMOS nodes and production test challenges
• Ability to work effectively in a cross-functional engineering environment

Preferred Qualifications

• Experience testing AI accelerators, GPUs, networking ASICs, or other high-performance compute ICs
• Experience with PCIe Gen5/Gen6, LPDDR4/5/6, or other high-speed interfaces
• Exposure to advanced packaging, chiplets, or multi-die test flows
• Experience improving yield, reducing test time, or optimizing cost in high-volume manufacturing
