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 d
