• 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:

• Degree/Master in Electrical/Electronic Engineering or equivalent

• Minimum 5 years hands-on experience in power electronics design and hardware systems, specifically for communication infrastructure or data centres
