Semiconductor Product Engineer (AI Accelerators)

Location: Bristol, United Kingdom

Company

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

What you will do

• Define manufacturing test strategies for AI accelerator chips targeting high-volume production.
• Plan and manage test content for advanced CMOS designs, including logic, SRAM, DRAM, and high-speed I/O.
• Develop and debug scan/ATPG, LBIST, MBIST, JTAG, and high-speed I/O test content.
• Bring up first silicon on ATE through pattern debugging, tester correlation, shmooing, and corner analysis.
• Characterize silicon, investigate failures, identify yield limiters, and optimize test coverage, time, and cost.
• Collaborate with DFT, design, packaging, OSAT, manufacturing, and external partner teams through qualification and production ramp.

Requirements

• 5+ years of hands-on semiconductor test engineering experience.
• Experience developing ATE test programs on Advantest 93K, Teradyne, or similar platforms.
• Strong understanding of DFT methodologies, including scan, ATPG, MBIST, and LBIST, together with memory test techniques.
• Experience debugging silicon issues 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.

Culture & Benefits

• High ownership and agency to drive work forward.
• Rapid iteration and direct collaboration with leadership to move from ideas to hardware.
• Close collaboration across hardware, software, silicon, and modelling teams.
• Private medical, dental, and vision coverage, contributory pension, and life/critical illness insurance.
• 25 days of holiday plus bank holidays, equity, and an inclusive office environment.

Hiring process

• Additional eligibility checks may be required because the work is subject to UK, US, and international export control regulations.
