Résumé du poste

Fractile is recruiting an experienced Semiconductor Product Engineer to lead the development and deployment of manufacturing test solutions for next‑generation AI accelerator devices. You will oversee the full silicon lifecycle from bring‑up to high‑volume production, defining test strategy and debugging complex silicon issues.

The role requires deep expertise in DFT, high‑speed interface testing, and CMOS manufacturing, with collaboration across design, packaging, and manufacturing teams.

Qualifications

• 5+ years of hands-on semiconductor test engineering experience.
• Experience developing ATE test programs (Advantest 93K, Teradyne, or similar).
• Solid 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

• Define and develop test methods and strategies for an AI accelerator chip targeting high‑volume manufacturing.
• 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 advanced packaging test flows, including die‑to‑die interconnect testing and package‑level thermal considerations.
• Contribute to documentation of test programs, debug procedures, and manufacturing release materials.
• Support qualification, reliability testing, and high‑volume manufacturing ramp.
