Principal Power Systems Architect- AI Accelerator Systems
$100,000 - $500,000 USD yearly
Define end-to-end power architecture for high-density AI accelerator racks using 800VDC distribution.
Originally posted 12 November 2026 by the employer.
About the role
This role defines and delivers power systems for high-density AI accelerator racks using 800VDC distribution, spanning from the data-center electrical interface through AC/DC conversion, high-voltage DC distribution, DC/DC conversion, rack busbars, protection, monitoring, and accelerator power delivery. The position leads technical execution across engineering teams to enable scalable 200 kW+ to 400 kW+ racks.
What you'll do
- Define end-to-end power architecture from facility AC distribution through conversion, 800VDC generation and distribution, rack busbars, intermediate and point-of-load conversion, and AI accelerator power delivery.
- Architect high-efficiency AC/DC and DC/DC conversion, evaluating distribution voltages, conversion topologies, centralized versus distributed designs, transient response, power quality, losses, thermal performance, and supplier solutions.
- Specify safe high-voltage DC distribution, including busbars, connectors, isolation, grounding, protection zones, DC arc interruption, pre-charge, discharge, interlocks, emergency shutdown, and regulatory compliance.
- Lead system integration across data-center infrastructure, rack mechanics, cooling, and accelerator platforms, setting requirements for power integrity, EMI/EMC, reliability, and thermal performance.
- Drive architecture from concept through production, covering detailed design reviews, prototype bring-up, characterization, safety and fault testing, supplier qualification, DFM, and manufacturing transition.
What you'll need
- BS or MS in Electrical Engineering, Power Electronics, or a related field, with 15+ years of experience in power electronics, power systems, or high-power electrical engineering.
- Experience architecting and developing high-power AC/DC and DC/DC conversion systems, three-phase AC systems, high-voltage DC distribution, and high-current busbars for complex products or infrastructure.
- In-depth knowledge of converter topologies, power semiconductors (Si, SiC, and GaN), magnetics, capacitors, connectors, protection devices, current sensing, thermal management, EMI/EMC, grounding, and isolation.
- Hands-on experience with system-level efficiency, transient, thermal, power-integrity, and fault analysis, taking power systems from architecture and prototype through validation and production.
- Demonstrated technical leadership setting roadmaps, evaluating system tradeoffs, leading design reviews, and guiding suppliers and partners.

How we counted: 62 open Power Electronics (Power Conversion) roles from 21 employers tracked in the SemiconductorJobs index, counted 12 Nov 2026. Specialty figures count only roles carrying this exact specialty label, so an employer's related work in neighbouring specialties is not included there, and is counted in the wider Analog & Mixed-Signal family row. Days are counted from when our index first saw each posting, not from the employer's original posting date.
