Descripción de la vacante

Rosaic Labs in Santa Clara, CA is seeking a Board-Level Power Engineer to own power delivery for next-generation server platforms. You will design the power architecture from busbar to load, and work hands-on from architecture to prototype bring-up in close collaboration with silicon, mechanical, thermal, and system teams.

This role requires 8+ years in power electronics for servers and HPC, with shipped designs, strong DC-DC, PDN design, and power integrity expertise.

Formación

• BS in Electrical Engineering or related field; MS preferred.
• 8+ years in board-level power electronics for servers/data centers.
• Shipped power delivery designs from architecture to production.
• Strong fundamentals in DC-DC converters, control loops, PDN design, and power integrity.
• Hands-on experience with power simulation and analysis tools.
• Working knowledge of current server and rack power solutions and ecosystem vendors.
• Lab expertise with oscilloscopes, electronic loads, network/frequency-response analyzers, and power analyzers.
• Read and guide PCB layout for high-current designs.

Responsabilidades

• Define board-level power architecture for server motherboards, accelerator modules, and rack power distribution (e.g., 48V/54V busbar to intermediate bus to point of load).
• Design high-current, low-voltage power delivery networks for high-performance silicon, including multiphase VRs for core rails exceeding 1,000 A with fast transient response.
• Evaluate and select power solutions — controllers, power stages, power modules, eFuses, hot-swap, and PMICs — and benchmark vendor offerings on efficiency, density, transient performance, cost, and supply risk.
• Run power simulations: PDN impedance and decoupling, loop stability, transient response, IR drop, efficiency, and thermal derating.
• Write schematics and guide PCB layout for power: stackup, plane design, current density, via sizing, and component placement.
• Lead prototype bring-up and validation: efficiency, ripple, load-step, Bode plots, sequencing, protection, and margining.
• Implement and debug digital power telemetry and control (PMBus, AVSBus/SVID) with firmware teams.
• Partner with silicon vendors to meet their power specs, and with thermal and mechanical teams on cooling and placement.
• Root-cause failures, and drive designs through compliance and production.
