Senior Principal, Design Engineering, Power Design

Senior Principal, Design Engineering

The Senior Principal, Design Engineering will be responsible for architecting, implementing, and supporting power system solutions for Networking, storage & server systems and related products. In this position you will help develop hardware solutions to be integrated into common platform designs including processors, high speed serial interfaces, NPUs, FPGAs, High speed memory (DDR4/DDR5) and high-speed PCB layout. You will work with design, software/firmware, mechanical and thermal engineers.

You will drive system architecture of multi-tiered power network design from rack level power distribution down to the board level POL solution. The successful candidate will work across disciplines to assure power supply designs meet the power, thermal, and safety requirements of the system specification. You will work closely with Celestica multi-disciplinary engineering and manufacturing teams to understand the system requirements and contribute or lead the specification, design, and debug of complex power delivery systems for datacenter products.

Skills & Responsibilities:

• Engage with customers and key suppliers on leading power solution architecture and solutions for high power systems such as AI/ML.
• Act as recognized power SME and trusted advisor to customers and internal stakeholders
• Drive related power technology roadmap initiatives with ecosystems, early customer engagement, and internal investment activities
• Develop power solution concepts with critical insights into trade-offs, risks, and benefits
• Develop and validate power systems requirements between customers and engineering
• Oversight, guidance, and review power development activity within engineering to ensure alignment to requirements and assist in key risk management mitigations
• Experience with high power, low noise, efficient, high density board level power design, including relevant simulations, analysis, test vehicles, and test plans
• Experience with system power architecture, subsystem and rack level, power redundancy strategies.
• Support engineering technical leads, power engineers, and SI engineers on constraints, components selection, power tree design, test plans, bring-up and debug as needed.
• Participate in industry organizations and supplier engagements driving leading edge power solutions

Experience:
