About The Position

We are seeking an experienced and proactive Senior Power DC-DC Hardware Engineer to drive end-to-end power delivery design for next-generation server platforms. In this role, you will lead the architecture, schematic design, layout constraint definitions, and comprehensive validation of complex board-level DC-DC converters and voltage regulator modules (VRMs). You will serve as a technical subject matter expert, resolving complex cross-functional challenges and mentoring junior engineers. The ideal candidate is self-motivated, results-driven, and passionate about developing best-in-class server products with outstanding performance and reliability.

Requirements

Bachelor’s or master’s degree in electrical engineering, Power Electronics, Computer Engineering, or a related discipline.
Minimum of 5+ years of hands-on hardware engineering experience with a primary focus on board-level DC-DC power design and server or enterprise computing hardware.
In-depth expertise in switch-mode power supply (SMPS) topologies (synchronous buck, multiphase buck, boost, isolated/non-isolated DC-DC converters).
Strong knowledge of multiphase VR controllers (e.g., IMVP/VR13/VR14 or equivalent), smart power stages (SPS/DrMOS), and digital power telemetry (PMBus, I2C, SVID).
Proficiency in schematic capture and netlist management tools (e.g., Cadence Allegro Design Entry HDL / OrCAD Capture).
Advanced lab skills using high-bandwidth digital oscilloscopes, electronic loads, programmable DC power supplies, frequency response analyzers.
Solid understanding of server power architectures, enterprise CPU/GPU/memory power delivery constraints, and fault protection mechanisms (OVP, OCP, UVP, OTP).
Proven track record of independently driving power hardware projects, resolving high-impact technical blockers, and collaborating effectively across multidisciplinary engineering teams.

Responsibilities

Lead the end-to-end design, schematic capture, and BOM selection for high-current server motherboard DC-DC power delivery systems, including multiphase voltage regulator modules (VRMs), point-of-load (POL) regulators, and power management circuits.
Perform component sizing, worst-case stress analysis, power loss calculations, and safe operating area (SOA) assessments for MOSFETs, power stages, inductors, controllers, and passive filtering networks.
Establish PCB power layer stackup constraints, define high-current routing strategies to minimize parasitic inductance and loop resistance, and collaborate closely with CAD/layout engineers on power integrity (PI) and EMI compliance.
Direct the bring-up, loop stability compensation, dynamic load transient tuning, ripple/noise verification, and power efficiency profiling across line, load, and temperature extremes.
Drive root-cause investigations and failure analysis (FMEA) for complex board- and system-level power anomalies in coordination with signal integrity, thermal, mechanical, firmware, and validation teams.
Interface with silicon partners and component vendors on custom part evaluations, roadmap alignment, and technical support; establish and document internal power design guidelines, review checklists, and validation standards.
Review schematics and layout artwork from junior engineers, providing technical guidance and mentoring across the hardware engineering team.
