We bet everything on the logical conclusion: that the only way to truly unlock this latent value, to make speed viable at scale, was to radically re-invent the hardware that we run our frontier AI models on. Ever since, we have been building chips and systems that tackle this problem: how to efficiently generate output at thousands of tokens per second, while handling the complexity and capacity challenges of operating large models at very long contexts.\nThe workloads that push to the limits of the current frontier are already transformational; it is the technical and economic limits on inference speed that are constraining progress. The defining work of the 21st century will be marked by the engine of inference delivering immense and diffuse chains of intellectual inquiry, in drug discovery, in software engineering, in materials discovery, in any field where progress is driven by deep reasoning and intelligence to resolve complex problems. \nThe Role\nThis role will design, implement, and support production-ready board/PCBA test solutions for a high-volume board integrating multiple AI accelerator chips, high-current power delivery, embedded control, and PCIe Gen6 interconnect. This is a hands-on individual contributor role focused on executing the board test strategy defined by the Board Test Engineering Lead and delivering robust, repeatable tests for offshore manufacturing.We are seeking an experienced DRAM Product Engineer to develop advanced test methodologies and diagnostic techniques for next-generation memory systems.\nThis role focuses on understanding DRAM behavior across logical, architectural, and physical domains, using simulation, statistical analysis, and mathematical modeling to investigate failure mechanisms, characterize performance margins, define test techniques and improve reliability and yield. The successful candidate will combine deep knowledge of DRAMarchitecture and circuit behavior with strong analytical and problem-solving skills, working closely with design, architecture, and manufacturing teams to drive memory test innovation and product quality.\nDevelop and execute test strategies for DRAM devices and their interconnects, covering functional, timing, signal integrity, and reliability failure modes.\nDiagnose complex DRAM issues across logical, architectural, and physical domains, including cell behavior, addressing, timing margins, and interface interactions.\nBuild, modify, and maintain simulation models to study DRAM behavior, interfaces, and test scenarios at multiple abstraction levels.\nUse simulation tools to explore corner cases, stress conditions, and failure mechanisms prior to and alongside silicon testing.\nTransform and correlate data between logical representations (addresses, transactions, algorithms) and physical implementations (cells, banks, rows/columns, wires, timing paths).\nAnalyze DRAM behavior with a deep understanding of circuit operation, including variability, noise, leakage, and process effects.\nApply statistical methods to large test datasets to identify trends, characterize distributions, isolate root causes, and support yield and reliability conclusions.\nUse mathematical models to describe, predict, and explore DRAM test behavior, limitations, and tradeoffs.\nCollaborate with design, architecture, and manufacturing teams to feed diagnostic insights back into design and test improvements.\nAbout you\nRequired Skills and Experience\nBS or MS in Electronics and Electrical Engineering or related field.\nStrong background in DRAM architecture, operation, and interfaces.\nSolid understanding of DRAM failure modes, and associated test and characterisation methods\nSolid understanding of advanced CMOS electronic circuit behavior and its impact on memory operation.\nExperience applying statistics to hardware test and characterization problems.\nStrong mathematical skills applied to modeling, analysis, and problem solving in test development.\nAbility to reason rigorously across abstraction levels, from physical circuits to logical test algorithms.\nPreferred Qualifications\nExperience with memory test, silicon bring-up, and failure analysis.\nExposure to SPICE or equivalent circuit-level simulation.\nExperience analyzing high-volume test data and yield trends.\nFamiliarity with manufacturing or system-level memory test environments.\nHow we work\nOwnership and execution: you will have full agency to drive your work forward\nRapid iteration: we all work directly with top leadership to move from idea to hardware on ambitious timelines\nFull-stack engagement: hardware, software, silicon, and modelling teams all work closely together to create a product with generational impact\nOptimistic and pragmatic: we possess the will to win, and to do the hard work to get us there\nTeam 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\nWhat We Offer\nCompetitive salary: A competitive salary reflective of your experience and the specialist nature of the role.\nEquity & Ownership: meaningful equity so everyone shares in the value creation\nBenefits: Private Medical, Dental and Vision, Contributory Pension, 25 Days holiday plus bank holidays and Life/Critical Illness Insurance.\nDiverse & fun office: we believe the hardest problems get solved by the broadest range of minds. We are committed to Equal Employment Opportunity through attracting and retaining a diverse team and building an inclusive environment. \nFractile is seeking to increase the clock speed of global progress, one chip at a time. We’ve recently raised $220M from investors including Founders Fund and Accel and our most important work lies ahead.
