Principal Systems Engineer — AI Data Center Power

Overview

As a Principal Systems Engineer, you will lead the technical and strategic definition of next-generation power management solutions for high-density AI data centers in 2026 and beyond. Your work will turn innovation in Intermediate Bus Converters (IBCs) and Hot-swap controllers into measurable business impact—growing market share, improving customer TCO, and accelerating time-to-market.

• High-impact scope:
  Shape the standards, architectures, and products that power the next wave of AI infrastructure.
• Cross-functional influence:
  Partner closely with product, R&D, operations, and executive leadership, as well as hyperscalers and industry bodies.
• Cutting-edge technology:
  Work at the forefront of GaN/SiC, HVDC distribution, VPD, advanced thermal management, and reference solution development.

• Shape Strategy:
  As the primary bridge between market needs and internal execution. Influence stakeholders across Product Lines, Business Lines, and corporate functions to secure R&D prioritization, capital allocation, and alignment for AI-focused roadmaps. Engage system architects at hyperscalers to shape their power delivery implementations.
• Architect Systems & Product Definition:
  Anticipate the evolution of rack bus architectures, including Vertical Power Delivery (VPD). Drive the integration of wide-bandgap materials (GaN/SiC) to meet the extreme transient requirements of generative AI workloads. Influence cross divisional roadmaps for Digital controllers, drivers, Aux power ICs, Hot Swaps, Efuses, POLs, IBC modules and FETs (GaN, Si, SiC).
• Turn Innovation into value:
  Ensure products directly address customer pain points—reducing data center energy use, improving rack reliability—while meeting revenue and schedule goals.
• Drive the Ecosystem:
  Influence standards and architectures through bodies such as the Open Compute Project (OCP) to align the industry with our technology roadmap.
• Define the Next Generation:
  Co-develop specifications for IBCs and Hot-swap solutions that match the rising power demands of future AI accelerators. Partner with hyperscale cloud providers to translate hardware roadmaps into scalable DC/DC topologies and system solutions. Prioritize reference designs with the highest ROI.
• Set the Vision:
  Lead the transition from 48V to 400V/800V HVDC distribution. Develop strategies for IBCs to handle higher input voltages safely and efficiently, and shape the semiconductor technologies and packages required to execute.

• Education:
  
  PhD in Electrical Engineering (Power Electronics focus).
• Experience:
  
  10+ years in the semiconductor industry with a proven track record launching high-volume power products.

• Customer Presence and Mindset
  • Strong on-site presence at customer locations; conduct deep technical reviews that build long‑term trust.
  • Customer‑first orientation focused on solving real pain points, not just selling silicon.
  • Executive presence; comfortable presenting to Division VPs and CTOs at major cloud providers.
• Technical Domain Mastery
  • Expert knowledge of isolated and non-isolated DC/DC topologies and Hot‑swap controller design.
  • Deep understanding of PDN impedance and thermal management in liquid‑cooled environments.
  • Proficiency in schematic/PCB design; hands‑on bring‑up, system debug, and lab validation.
  • Clear understanding of hardware/firmware/software interactions in system design.
  • Ability to create, review, and approve engineering requirements specifications.
  • Capability to model and characterize power systems and components.
• Business Acumen
  • Demonstrated ability to balance cost/performance trade‑offs and present compelling business cases for new investments.

• Experience with 800V HVDC distribution and emerging high‑voltage data center safety standards.
• Strong commercial mindset; ability to identify blue‑ocean opportunities where innovation meets unmet market needs.
• Knowledge of AI accelerator power profiles to guide application‑specific power ICs.
