About the role

Key responsibilities & impact

Own hardware schematic design for multi-phase buck regulators, point-of-load converters, and power sequencing circuitry.
Select critical power components, including passives, inductors, power stages, controllers, and supporting circuitry.
Define placement and routing constraints for board-level power delivery networks, including decoupling capacitor strategy and high-current power paths.
Work closely with package engineering to ensure clean power delivery handoff at the socket or package interface.
Lead lab validation of power subsystems, including VRM efficiency, loop stability, DC IR drop, thermal behavior, and transient response.
Use oscilloscopes, electronic loads, network analyzers, thermal cameras, and related lab equipment to characterize power rails under maximum dynamic load conditions.
Partner with SI/PI engineers to measure and mitigate power supply noise and Power Supply Induced Jitter on sensitive high-speed lanes.
Debug power integrity issues across board, package, silicon, firmware, workload, and system-level interactions.
Contribute to design guidelines, validation plans, and best practices for power delivery across the company’s hardware platforms.

Requirements

What you’ll need

Extensive experience designing high-current, multi-phase DC-DC regulators for high-power ASICs, GPUs, processors, accelerators, or similar compute platforms.
Strong background in power hardware design for systems with 500W+ devices or comparable high-current power delivery requirements.
Deep understanding of board-level PDN implementation, decoupling strategy, power sequencing, transient response, and voltage regulation.
Hands-on experience with schematic capture and layout oversight for complex power delivery systems, preferably using tools such as Cadence Allegro or Concept.
Strong lab validation skills using electronic loads, oscilloscopes, network analyzers for loop stability testing, thermal cameras, and related power measurement equipment.
Experience characterizing VRM efficiency, bode plots, DC IR drop, ripple, noise, and transient behavior under dynamic workloads.
Proficiency with SPICE-based time-domain circuit simulation or similar power simulation workflows.
Ability to collaborate closely with SI/PI, package, hardware, firmware, and systems teams in a fast-moving engineering environment.
