Job description

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.

You will own the strategy, specification, and development of test solutions for a high-volume production board/PCBA that integrates multiple AI accelerator chips, high-current power delivery, embedded control, and PCIe Gen6 interconnect. Lead and manage internal and external engineering teams to deliver robust, scalable test infrastructure for offshore manufacturing.

Key Responsibilities

• Define the end-to-end board/PCBA test strategy for a complex board containing multiple AI accelerator chips, high-current VRMs, local MCU, and PCIe Gen6 board-to-board and chip-to-chip links.
• Develop detailed test requirements, coverage goals, and manufacturing test specifications (ICT, boundary scan, functional test, system-level test).
• Lead the design and deployment of the board/PCBA test solution for offshore high-volume manufacturing, including fixtures, test stations, instrumentation, and automation architecture.
• Collaborate with hardware, firmware, power, and SI/PI teams to ensure testability is designed-in early (DFT/DFM for board-level manufacturing and test).
• Oversee MCU-based board-level test features (self-test firmware, sensor/telemetry validation, SPI/I2C/GPIO test hooks).
• Coordinate with CM/EMS partners to ensure manufacturability, repeatability, throughput, and yield targets are met; establish KPIs for board test performance.
• Lead root-cause failure analysis and test-based diagnostics for assembly defects, component issues and manufacturing marginalities and weaknesses.
• Own documentation for test specifications, test flow, acceptance criteria, debug procedures.
• Implement data collection, logging, and analytics for yield, performance trends, and field-return correlation.
• Manage external partners developing fixtures, test software, and custom instrumentation; track schedules and deliverables.
• Partner with product engineering to align board test with system characterization, environmental stress testing, and reliability validation.

Required Qualifications

• BS/MS in Electronics and Electrical Engineering or related field.
• 8+ years in board/PCBA test engineering, with ownership of high-volume production test solutions.
• Experience defining test strategies for complex digital boards with high-speed IO and significant power delivery requirements.
• Strong hands-on experience with functional testers, fixture development, boundary scan/JTAG, ICT, and automated manufacturing test flows.
• Experience with embedded test firmware and MCU-driven diagnostics (Zephyr or similar RTOSes a plus).
• Proven ability to work with offshore EMS/CM partners and manage external test development vendors.
• Strong analytical and debug skills across digital logic, power electronics, and high-speed serial links.

Preferred Qualifications

• Experience with boards designed around AI accelerators, GPUs, networking ASICs, or other high-power/high-speed compute hardware.
• Familiarity with high-current VRMs, multiphase converters, and related test methodologies.
• Knowledge of automated factory data systems, test data analytics, and yield-improvement processes.
• Experience with advanced board-to-board and chip-to-chip signal integrity test in a production test environment.

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 70+ which is expanding rapidly
• Modern, open offices in London and Bristol
• Collaborative, problem-solving culture built on deep curiosity, entrepreneurial initiative and technical fluency
