Principal Systems Engineer — AI Data Center Power

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.

Your Role

Key responsibilities in your new role

• 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, HotSwaps, Efuses, POLs, IBC modules and FETs (GaN, Si, SiC).
• Turn Innovation into value: Ensure products directly address customer pain points—reducing data centre 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. Prioritise 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.
