Senior Hardware Engineer (Power) - Bedok - #1164844

About the role

Senior Hardware Engineer role focused on defining power supply architectures for data centre servers and rack-level systems, optimizing for maximum efficiency and power density. The role involves designing system power trees, performing power budgeting calculations, and selecting power supply solutions for high DC input voltage conversion to desired high current low voltages for digital circuitries.

Key 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:

• 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

• Deep understanding of power design topologies (e.g. buck, boost) and hands-on experience with Wide-bandgap (WBG) semiconductors like GaN and SiC

• Understanding integration of software and hardware required

• NPI project execution experience and familiarity with Product Development Life Cycle will be desirable

• Experience using CAD tools (e.g. Cadence Allegro, Siemens PADS or Altium Designer)

• Experience with power integrity (PI) simulation tools is highly advantageous

• Familiar with ISO9001

• Strong analytical skills for root cause analysis and resolving complex system-level issues

• Self motivated and willing to learn new technology and skills who works well under pressure

• Self motivated and willing to learn new technology and skills who works well under pressure

• Maintain effective working relationships with managers, co-workers

• Excellent organization skills and ability to juggle multiple projects

• Excellent oral and written communication skills
