Company

hirify.global is developing specialized chips and systems to accelerate inference for frontier AI models.

What you will do

• Develop and maintain ATE test programs for AI accelerator chips through high-volume manufacturing.
• Implement structural and functional manufacturing tests for advanced CMOS designs, including scan/ATPG, LBIST, MBIST, JTAG, SRAM, DRAM, and high-speed I/O.
• Bring up first silicon on ATE through pattern debugging, tester correlation, shmooing, and corner analysis.
• Test high-speed interfaces such as PCIe Gen6 and multi-GHz LPDDR, including at-speed testing and margining.
• Perform silicon characterization and failure analysis to identify yield limiters and defect mechanisms.
• Optimize test coverage, test time, cost, and manufacturing robustness while collaborating with design, DFT, packaging, OSAT, and manufacturing partners.

Requirements

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

Nice to have

• 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.
