Résumé du poste

Fractile in the United Kingdom seeks an experienced Semiconductor Product Engineer to lead the development and deployment of manufacturing test solutions for next-generation AI accelerator devices. You will own the full silicon lifecycle, from first silicon bring-up to high-volume production, defining test strategy and optimizing yield and cost.

The ideal candidate will have deep expertise in DFT, high-speed interface testing, and CMOS manufacturing, collaborating with design, DFT, packaging,

Qualifications

• 5+ years of hands-on semiconductor test engineering experience.
• Experience developing ATE test programs (Advantest 93K, Teradyne, or similar).
• Strong understanding of DFT methodologies (scan, ATPG, MBIST, LBIST) and memory test techniques.
• Experience debugging silicon issues and correlating failures to design or process causes.

Responsabilités

• Plan and manage 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, including at-speed tests and margining features.
• 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 deployment.
• Support qualification, reliability testing, and high-volume manufacturing ramp.
