Senior Hardware Engineer (Power Electronics)

Job Responsibilities:

Define power supply architectures (AC/DC and DC/DC) for data centre servers and rack-level systems, optimizing for maximum efficiency and power density

Design system power trees, and perform power budgeting calculations. Determine thermal power budget and work with thermal engineers to provide thermal solutions

Design and select power supply solutions for high DC input voltage from 12-400V to the desired high current low voltages for digital circuitries

Analyze power supply conversion efficiency, calculate thermal dissipation, and perform loss budgeting for switching devices, magnetic, and passive components

Perform schematic capture and guide PCB layouts to minimize EMI/EMC and ensure signal/power integrity

Conduct rigorous simulations for power conversion efficiency, thermal management, and magnetic design

Perform board bring-up, characterize designs and validate power consumption against calculated budget, and execute lab testing

Work with firmware, mechanical and thermal design teams to ensure power supply solutions meet physical and cooling constraints

Ensure designs meet international safety and regulatory requirements and align with Open Compute Project (OCP) standards

Work with cross functional and manufacturing team to resolve design issues and to support production problems

Provide technical expertise and consultation to peers

Maintain consistent high quality of engineering design work to develop robust, high performance and cost effective designs and products

Meet project schedules and budgets

Perform additional duties as assigned

Job Requirements:
