DFT 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. Join the team implementing DFT for a large, multi-core AI accelerator ASIC. You will work on scan, ATPG, and memory test, contributing to a robust and scalable test solution while developing your expertise in advanced SoC design. Key Responsibilities Contribute to the DFT architecture of a multi-core AI accelerator SoC Drive integration of DFT tools into the EDA flow Implement scan insertion, compression, and test logic Generate and analyze ATPG patterns for structural faults Support MBIST implementation for embedded memories Work with physical design to ensure clean scan chain implementation and timing closure Develop scripts and automation to improve DFT workflows Support silicon bring-up, debug, and test analysis Work with test and product engineering teams to bring up and debug ATPG patterns on ATE, supporting production test and yield ramp Required Experience Degree in Electrical Engineering, Computer Engineering, or similar Experience in DFT, digital design, or related ASIC development Good understanding of scan, ATPG, memory BIST and digital test concepts Familiarity with mainstream EDA tools Scripting skills (Python, Tcl, or similar) Profile Eager to learn and grow in DFT and large-scale ASIC design Detail-oriented and comfortable working with complex systems Collaborative and responsive in a fast-moving team How we work Ownership and execution: you will have full agency to drive your work forward Rapid iteration: we all work directly with top leadership to move from idea to hardware on ambitious timelines Full-stack engagement: hardware, software, silicon, and modelling teams all work closely together to create a product with generational impact Optimistic and pragmatic: we possess the will to win, and to do the hard work to get us there Team player mentality: the mission is bigger than any of us, and we have the curiosity and technical focus to see the best idea shipped, no matter who’s it is About us Founded in 2022, team of 80+ which is expanding rapidly Modern, open offices in London and Bristol Collaborative, problem-solving culture built on deep curiosity, entrepreneurial initiative and technical fluency Export control and security clearance Certain roles may involve working on technologies subject to export restrictions.
