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.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Required Qualifications
- 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.
