Requisition ID: 112780-0
Senior Engineer II (Hardware Design)
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:
• 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
• Maintain effective working relationships with managers, co-workers
• Excellent organization skills and ability to juggle multiple projects
• Excellent oral and written communication skills
