You will own board designs end to end — architecture, schematic capture, component selection, layout direction and the design reviews that get them built. This is a hands-on ownership role: the boards you design are the ones the team brings up, debugs and ships.
What you will work on:
• Schematic design and ownership of boards for an AI accelerator platform
• Component selection and sourcing trade-offs, from silicon to passives
• Layout direction and constraint definition, working alongside PCB designers
• Design reviews, DFx and the path from prototype through to production
• Respins and ECOs driven by test, bring-up and field feedback

Responsibilities:
• Schematic capture & ownership: Own the full schematic for assigned boards — architecture, block partitioning, interface definition, power tree and sequencing. Maintain the design through revisions, ECOs and respins.
• Component selection: Select and specify components against electrical, thermal, cost, lifecycle and supply constraints. Own the BOM, including second sourcing and obsolescence risk.
• Layout direction:



Define stackup, placement intent, routing constraints and keep-outs. Review layout against SI, PI, power and thermal requirements, and drive the iterations to closure.
• Design verification: Run circuit-level simulation where it matters, build and check timing and interface budgets, and perform worst-case analysis on critical nets and rails.
• Cross-functional & lifecycle: Work with SI/PI, power, thermal, mechanical and firmware teams to fold their requirements into the design. Drive formal design reviews, hand the board off cleanly to the bring-up team with the documentation they need, and take it through NPI with manufacturing partners.

Requirements:
• 5+ years designing complex digital boards — server, datacentre, networking, or comparable high-speed systems
• Proven ownership of schematic capture on multi-layer boards carrying high-speed interfaces, from concept to production
• Strong grasp of di
