Electrical Engineer, Rack Power Distribution

Job description

About the Company

General Matter is enriching uranium in America.

Our goal is to design, build, and operate the world’s lowest-cost enrichment services in the United States.

Our mission is to restore America’s ability to produce nuclear fuel—fuel that will power AI, advanced manufacturing, critical industries, and the next generation of nuclear reactors.

Ultimately, our work will help power national ambitions and enable a high-energy society.

We were incubated by Founders Fund, like Anduril and Palantir before us, and are backed by top-tier investors. Our lean, world-class team of engineers and operators is applying a first-principles approach to solving the problem of nuclear fuel production.

We are a mission-driven company with a culture of urgency, accountability, and transparency.

Help us build a high-energy society by making the cleanest, safest form of baseload energy the most affordable.

About This Role

We're building our enrichment facilities and the high-density computing infrastructure behind them. We're hiring an Electrical Engineer to own power distribution inside the rack. You'll define how power gets from the facility tap-off to every server PSU in our high-density racks. That means selecting PDUs and power shelves, laying out busbars, assigning outlets and phases, and making sure every rack stays up when a feed goes down.

This is a hands-on design role, not a specification-only role. We want someone who has designed rack power, tested it, found the problems, and fixed them. You'll be the technical authority on rack power and the bridge between our facility electrical team and our IT hardware team. You'll set the technical foundation for work of lasting national importance.

If you seek high impact and are excited by fast-paced, intense, Skunkworks-style projects, we encourage you to apply to join our team.

Responsibilities

Rack Power Architecture

• Own the rack power architecture end to end, from busway tap-off or RPP through rack PDUs, in-rack busbars, and power shelves to server PSUs

• Define rack power topologies for high-density AI/GPU and HPC deployments (50–130+ kW per rack), including 48V/54V busbar (OCP ORv3) and liquid-cooled configurations

• Set redundancy strategy at the rack level (A/B feeds, PSU N+1 and N+N) and verify failure-mode loading under single-feed operation

Detailed Design & Analysis

• Select and specify rack PDUs (metered, switched, intelligent), power shelves, BBUs, and power cords and whips (IEC C13/C19/C20, IEC 60309, NEMA L21)

• Produce rack elevations with power assignments, outlet-level load schedules, and phase-balance calculations

• Analyze inrush current, hold-up time, breaker coordination at the branch and rack level, voltage drop, and connector and busbar thermal loading

• Size branch circuits, tap-offs, and RPP circuits feeding each rack, and set derating and power-capping strategy for variable GPU workloads

Integration & Validation

• Work directly with server OEMs, ODMs, and PDU and power shelf vendors on design reviews, submittals, and technical issues

• Coordinate with facility electrical, mechanical/liquid cooling, controls, and IT hardware teams to resolve rack-to-facility interface issues

• Lead rack power validation through lab testing, factory integration, and on-site commissioning, and drive root cause on any power issue found

• Integrate rack power monitoring (intelligent PDUs, branch circuit monitoring) with DCIM

Design Control

• Prepare design packages that move through formal engineering review, configuration management, and change control

• Ensure compliance with NEC (NFPA 70), NFPA 70E, NFPA 75, applicable IEEE standards, and UL/IEC listing requirements for rack equipment

Basic Qualifications

• B.S. in Electrical Engineering or a closely related field

• [5+] years of electrical design experience, with at least [3] years designing power distribution at the rack and server level for data center or hyperscale deployments

• Direct design experience with rack PDUs, in-rack busbars, power shelves, or server power delivery, not only facility-level MEP design

• Strong command of A/B redundancy, phase balancing, branch circuit sizing, inrush, and PSU redundancy behavior

• Experience taking rack power designs through testing, integration, or commissioning

• Proficiency producing rack elevations, load schedules, and one-line diagrams (AutoCAD, Revit, Visio, or similar)

• Must be a U.S. person (export control requirement) and able to obtain and maintain a U.S. government security clearance [FSO to confirm wording]

Preferred Skills and Experience

• Experience with high-density AI/GPU racks such as NVIDIA GB200/GB300 NVL72, MGX, or comparable platforms

• Experience with OCP Open Rack (ORv3), 48V/54V busbar, BBU systems, or emerging higher-voltage DC rack architectures

• Liquid-cooled rack integration experience (power and cooling interface, CDU and manifold coordination)

• Background on a hyperscaler hardware team,
