Semiconductor Test Engineer

Fractile is building silicon, systems and software which will redefine the frontier of AI: running the world’s most advanced models at radically higher speed and lower cost. We have an exceptional team across hardware and software capable of bringing about this change, and we are growing fast to meet demand and deliver our product at scale. Summary We are seeking an experienced Semiconductor Test Engineer to lead the development and deployment of manufacturing test solutions for next-generation AI accelerator devices. This role spans the full silicon lifecycle from first silicon bring-up through high-volume production, with responsibility for defining test strategy, developing ATE test content, debugging complex silicon issues, and optimizing yield, coverage, and test cost. The ideal candidate will bring deep expertise in DFT methodologies, high-speed interface testing, and advanced CMOS manufacturing, and will work closely with design, DFT, packaging, and manufacturing partners to ensure robust, scalable production of high-performance compute silicon. Key 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.
