Electrical Engineer, Rack Power Distribution

General Matter • Los Angeles, CA

8d • $170,000 - $250,000

About The Position

General Matter is building uranium enrichment facilities and the high-density computing infrastructure behind them. The Electrical Engineer will own rack-level power distribution, defining how power flows from facility tap-offs to server power supply units in high-density racks. This hands-on design role includes selecting power distribution units and power shelves, laying out busbars, assigning outlets and phases, and ensuring racks remain operational when a feed fails. The engineer will serve as the technical authority on rack power and connect the facility electrical team with the IT hardware team. The work supports the company’s mission to restore domestic nuclear fuel production and enable affordable, clean baseload energy. The company describes its culture as mission-driven, fast-paced, intense, and Skunkworks-style, with urgency, accountability, and transparency.

The role covers rack power architecture for high-density AI/GPU and HPC deployments, detailed electrical design and analysis, vendor and cross-functional coordination, validation and commissioning, and design control. Designs must address rack loads of 50–130+ kW, redundancy and failure modes, applicable electrical and equipment standards, and formal engineering review and configuration management.

Requirements

• B.S. in Electrical Engineering or a closely related field.
• At least 5 years of electrical design experience, including 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; facility-level MEP design alone is not sufficient.
• 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 using AutoCAD, Revit, Visio, or similar tools.
• Must be a U.S. person for export-control purposes and able to obtain and maintain a U.S. government security clearance.
• Ability to work extended hours and weekends as necessary.

Nice To Haves

• 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, including power and cooling interfaces and CDU and manifold coordination.
• Background on a hyperscaler hardware team, AI rack integrator, ODM, or rack PDU or power shelf manufacturer.
• Familiarity with facility-side distribution, including busway, RPPs, and UPS, and power system tools such as ETAP, SKM, or EasyPower.
• Professional Engineer (PE) license.
• Experience in a regulated industry such as nuclear, aerospace, defense, or pharma, with formal design control or QA programs.

Responsibilities

• Own rack power architecture 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, including 48V/54V busbar (OCP ORv3) and liquid-cooled configurations.
• Set rack-level redundancy strategies, including A/B feeds, PSU N+1 and N+N, and verify failure-mode loading under single-feed operation.
• Select and specify rack PDUs, power shelves, BBUs, power cords, and whips.
• Produce rack elevations with power assignments, outlet-level load schedules, and phase-balance calculations.
• Analyze inrush current, hold-up time, breaker coordination, 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 strategies for variable GPU workloads.
• Work 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 analysis of power issues.
• Integrate rack power monitoring, including intelligent PDUs and branch circuit monitoring, with DCIM.
• Prepare design packages for 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.
• Work extended hours and weekends as necessary.

Benefits

• Long-term incentives in the form of stock options may be available to full-time hires.
• Medical coverage.
• Vision coverage.
• Dental coverage.
• Access to a 401(k) retirement plan.
