Senior PCB Layout Engineer – HDI, FPGAs & SI/PI

MAI Agents; Oxford; Presencial; GBP 85.000 - 110.000; Jornada completa

Descripción de la vacante

Lumai is an optical compute company spun out of the University of Oxford, building AI infrastructure. We’re looking for a seasoned PCB layout engineer to own board layout from schematic handoff to fabrication release.

You will manage HDI structures for high-layer-count boards, ensure signal and power integrity, collaborate with hardware teams, and deliver complete manufacturing outputs, libraries, and CAD standards. Oxford-based, with impact across volume production.

Formación

• Extensive professional experience laying out complex, high-speed, high-layer-count boards, with production-ready designs.
• Expert proficiency in Cadence Allegro, including Constraint Manager; Equivalent Altium experience will also be considered.
• Hands-on experience with HDI technologies: microvias, via-in-pad, stacked and staggered vias, and back-drilling.
• Proven BGA breakout and placement for large, fine-pitch devices such as FPGAs and ASICs.
• Thorough knowledge of IPC standards (IPC-2221, IPC-7351, IPC-6012) and DFM/DFA/DFT principles.

Responsabilidades

• Lay out dense, high-layer-count PCBs from schematic through to fabrication release, using constraint-driven flows.
• Implement controlled-impedance routing, differential pair and length/phase matching, and HDI structures including microvias, via-in-pad and back-drilling.
• Plan BGA breakout and component placement for large FPGAs, custom ASICs and fine-pitch packages, balancing SI, PI, thermal and mechanical requirements.
• Translate SI/PI and hardware constraints into layout rules, and iterate quickly with engineers on simulation feedback.
• Run DFM, DFA and DFT reviews, and act as the main technical contact with PCB fabricators and assembly houses.
• Generate complete manufacturing outputs (Gerber/ODB++, drill files, assembly drawings, fabrication notes) and manage design revisions.
• Own and maintain the footprint and symbol libraries, CAD standards and design templates, compliant with IPC standards.
