Job description

About Valar Atomics

At Valar Atomics, we're redefining what's possible in energy. Our mission is to make clean, high-temperature nuclear power scalable-unlocking abundant energy for industry, hydrogen, and next-generation manufacturing. We are a team of builders, engineers, and operators who believe nuclear energy should be fast to deploy, factory-made, and built for the real world. Our first pilot plant in Orangeville, Utah will demonstrate how advanced nuclear systems and fuel fabrication can power the future. Joining Valar Atomics means becoming part of a company where autonomy, ownership, and impact exist at every level.

The Team

You will be joining Valar Atomics' Instrumentation, Control & Electrical (IC&E) organization, supporting design work across the Reactor, Nuclear Fuel, Power Conversion, and Power Distribution areas. Electrical Designers own the drawing packages that define the physical electrical and instrumentation installation one-lines, schematics, wiring and loop diagrams, cable and raceway layouts, panel arrangements, and installation details. You will work alongside electrical, I&C hardware, I&C software, process, mechanical, and nuclear safety engineers in a hands-on environment where drawing quality and installation integrity directly support plant reliability and nuclear safety. The team values technical depth, disciplined documentation, and a safety-first culture.

The Role

Valar Atomics is seeking Senior Electrical Designers to develop electrical and instrumentation design deliverables across the full plant scope: Reactor, Nuclear Fuel, Power Conversion, and Power Distribution. The role covers power distribution and control system drawings, cable and raceway design, control panel layouts, grounding and lightning protection layouts, hazardous area drawings, and instrument installation details supporting programs from early design and licensing through construction, commissioning, and ongoing operations. This is a senior position: you will own drawing packages end-to-end, from development through checking, issue, and as-built incorporation, and provide checking and technical direction to junior designers and drafting contractors.

Key Responsibilities

• Develop and maintain electrical design deliverables including single-line and three-line diagrams, schematics, wiring and interconnection diagrams, panel schedules, load lists, and motor elementary diagrams across Reactor, Nuclear Fuel, Power Conversion, and Power Distribution scopes.
• Design power distribution layouts covering switchgear, MCCs, panelboards, transformers, UPS and DC systems, receptacle and lighting circuits, and equipment power feeds; incorporate load, voltage drop, and short-circuit data provided by electrical engineers.
• Perform cable and raceway design including cable schedules, cable sizing and voltage drop checks, tray and conduit routing, fill and derating calculations, and signal/power segregation per project standards, including segregation and separation requirements for safety-related and non-safety circuits.
• Produce control panel and enclosure design drawings including internal layout, wiring diagrams, terminal and marshalling arrangements, nameplate schedules, and bills of material consistent with UL 508A practice.
• Develop grounding, bonding, and lightning protection layouts including grounding grids, equipment bonding details, instrument and shield grounding, and equipotential plane details.
• Prepare hazardous area classification drawings and ensure equipment layout and wiring methods in classified areas comply with NEC Article 500/505 or IEC 60079.
• Develop instrumentation installation deliverables including hook-up drawings, instrument location plans, loop diagram drafting, junction box layouts, and cable block diagrams in coordination with I&C hardware engineers.
• Apply and enforce CAD standards, drawing templates, title blocks, symbol libraries, layer conventions, and file organization on assigned scope, including contractor-produced drawings, and contribute improvements to the discipline's standards.
• Generate bills of material and material take-offs for cable, raceway, panels, and installation hardware; support requisitions and procurement technical evaluations.
• Perform field walkdowns to verify routing, constructability, and existing conditions; capture redlines and produce as-built drawings and turnover documentation.
• Review and redline vendor drawing packages, contractor shop drawings, and installation deliverables for compliance with project standards and nuclear quality requirements.
• Coordinate drawing content with piping, structural, mechanical, and HVAC designers to resolve routing conflicts, clearances, and access requirements, including work within 2D and 3D plant models.
• Support construction and commissioning teams with drawing clarifications, RFI responses, field change documentation, and punch list resolution.
• Maintain drawing revision control and document management practices co
