Semiconductor Product Engineer

Key Responsibilities

• Develop, deploy and maintain ATE test programs for high-volume manufacturing of AI accelerator chips and pre-silicon test vehicles

• 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, characterisation, and corner analysis.

• Optimize test coverage, test time, and cost while maintaining manufacturing robustness.

• Collaborate with subcontracted test program development partners.

• Collaborate with OSATs and external partners on test program execution and debug.

• Support qualification, reliability testing, and high-volume manufacturing ramp.

Required Qualifications

• BS or MS in Electronics and Electrical Engineering or related field.

• 5+ years of hands-on semiconductor test engineering experience.

• Strong experience developing ATE test programs (Advantest 93K, or similar).

• Solid understanding of DFT methodologies (scan, ATPG, MBIST) 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 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.

• Experience in test hardware procurement (probe cards, load boards, sockets).

You will help Fractile bring its memory technology into production, establishing effective test coverage, resolving manufacturing issues and ensuring we deliver the performance, quality and scale our compute platform needs.
