Semiconductor Test Engineering Team Leader

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. We are seeking a senior Semiconductor Test Engineering leader to drive manufacturing test strategy and silicon production readiness for next-generation AI accelerator devices. This role combines deep technical expertise in high-performance compute silicon with leadership responsibility for internal product engineering teams and external development partners. The successful candidate will oversee all aspects of production test development — from DFT strategy and ATE bring-up through silicon characterisation, yield optimisation, advanced packaging test, and high-volume manufacturing ramp — ensuring robust, scalable, and cost-effective test solutions for advanced AI accelerator platforms. Key Responsibilities Drive the manufacturing test strategy for an AI accelerator chip featuring PCIe Gen6, LPDDR, advanced CMOS nodes, and advanced packaging (e.g., 2.5D/3D, chiplet). Lead and manage a team of chip test engineers responsible for test planning, test program development, pattern bring-up, silicon characterization, debug, and optimization. Manage subcontracted test development partners (OSATs, ATE vendors, external engineering services). Includes scoping, technical oversight, schedule tracking, and quality control of deliverables.
