As a Server/Storage DC/DC Power Engineer, you will own the end-to-end power delivery architecture and design for high-performance server systems, spanning from project kick-off to mass production. You will serve hyperscale/enterprise customers and deliver robust, high-efficiency, and high-density power solutions. ESSENTIAL DUTIES AND RESPONSIBILITIES Technical Engagement : Serve as the primary power technical counterpart for server clients (OEM/ODM/Hyperscalers); participate in weekly technical reviews to track design status, resolve alignment issues, and manage deliverables. System Power Architecture : Collaborate with project leads, and system architects to define server-level power delivery architectures (e.g., 12V/48V DC bus, CRPS infrastructure). Topology & Budget Analysis : Analyze complex server power budgets to construct detailed power block diagrams and select optimal topologies (Buck, Boost, Buck-Boost, Isolated DC-DC). High-Power Subsystem Design : Own the design of server power subsystems, including high-current Multi-phase CPU/GPU Core VRMs (Intel VR14/AMD SVI3 specs), DC-DC POL converters, Hot-swap/E-fuse control, AC/DC CRPS Oring/Current sharing circuits, Telemetry/Digital Power Management (PMBus/I2C/SVID), EMI filtering, and Super-capacitor/BBU (Battery Backup Unit) management. Supplier & Component Management : Partner with tier-1 vendors to evaluate and select critical components (Controllers, Power Stages/DrMOS, Inductors, Low-ESR Capacitors, High-current Connectors, Busbars) balancing efficiency (80 Plus Titanium standards), thermal performance, cost, and form factor. Schematic Capture & Simulation : Utilize CAD tools (OrCAD Capture / LTspice) to generate schematics and perform rigorous power integrity (PI) simulations and loop stability calculations to guarantee transient response and reliability. Layout Guidance : Establish strict power-specific layout guidelines for high-current paths and work closely with Layout Engineers on component placement, thermal dissipation, and critical power-path routing reviews. Board Bring-Up : Collaboratively drive initial server motherboard/baseboard bring-up and firmware debugging (BMC/PMBus integration) alongside Electrical (EE) and Firmware (FW) Engineers. Server Test Planning : Develop comprehensive DC-DC test plans incorporating generic industry standards, OCP (Open Compute Project) specs , and custom client specifications (Full validation for EVT; Regression/Stress testing for DVT). Hands-on Verification : Execute test plans (including dynamic load transient, efficiency profiling, ripple/noise, and thermal stress), analyze data, and author official power validation test reports. Root Cause Analysis : Spearhead troubleshooting and failure analysis for power defects, implementing required ECOs (Engineering Change Orders) into DVT schematics and board files. Second-Source Qualification : Review and validate second-source components recommended by Component Engineers; execute qualification test plans to ensure server-grade reliability. NPI & Manufacturing Support : Provide technical support to the manufacturing and factory teams to resolve power-related issues during server pilot runs and mass production. RMA Failure Analysis : Support sustaining engineering by performing deep-dive failure analysis (FA) on server power-related field returns (RMA). Equipment Mastery: Proficient in operating advanced lab equipment for
