Director, Fuel Equipment Engineering, Valarin (Fuel Plant)

Valar Atomics is a nuclear energy company focused on scaling high-temperature gas reactors (HTGRs) for grid-independent industrial applications. The company is developing what it calls gigasites, large-scale facilities housing hundreds of nuclear reactors intended to power heavy industry, data centers, hydrogen production, and clean hydrocarbon fuel synthesis. Their reactor design uses TRISO fuel, a graphite moderator, and helium coolant, a combination the company highlights for its strong safety profile and proliferation resistance. By operating outside the traditional electricity grid, Valar Atomics aims to unlock economies of scale that have historically eluded the nuclear industry. Valar Atomics' mission centers on making nuclear energy the cheapest and most reliable energy source in the world, with a particular emphasis on decarbonizing industrial processes and enabling clean fuel production. Their hydrogen output, generated via a sulfur-iodine thermochemical cycle, can be combined with captured CO2 to produce synthetic hydrocarbons through a modified Fischer-Tropsch process, offering a pathway to drop-in clean fuels. The company also targets the surging power demands of AI data centers, which are projected to require over 200 additional terawatt-hours of grid power by 2030. The company is currently advancing its Ward 250 project, a test reactor being developed in partnership with the U.S. Department of Energy, the San Rafael Energy Research Center, and the State of Utah, with a target go-live date of July 4, 2026, America's 250th birthday. The reactor has already been physically transported to Emery County, Utah, with logistical support from the U.S. military. Four executive orders issued under the Trump administration provided a mandate supporting the project's accelerated deployment timeline.

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 

As part of the Engineering organization, Mechanical Engineering designs and develops the mechanical systems, components, and equipment that power Valar's advanced nuclear technologies. The team ensures designs are robust, manufacturable, and optimized for long-term performance. 

 

The Role 

Our TRISO fuel fabrication line turns U3O8 powder into finished TRISO compacts through three core process families: sol-gel kernel production, chemical vapor deposition (CVD) coating, and high-temperature furnace processing. Each runs on purpose-built process skids that our team designs, procures, builds, and commissions. 

The Director of Fuel Equipment Engineering owns the design of that equipment end to end: from early skid design through to fabrication, factory and site acceptance testing, commissioning, and handover to fuel production operations. 

This role is a hands-on technical authority who understands chemical process equipment, fluidized-bed reactors, and high-temperature furnace systems at a deep level. It is also a team leader who builds and develops the equipment engineering organization as the fuel program scales.

 

Key Responsibilities 

Technical Leadership — Fuel Process Equipment 

• Own the equipment design basis for the full TRISO fabrication flow, from U3O8 receipt through finished coated particle
• Oversee technical leads for each equipment family and guide the design and commissioning of that equipment
• Define skid architecture standards: modularity, materials of construction, containment and confinement, maintainability, and remote or glovebox operation where required
• Partner with process engineering to translate process recipes and critical parameters into equipment requirements that deliver repeatable kernel and coating quality
• Ensure equipment designs meet nuclear criticality safety, radiological protection, chemical hazard, and fire protection requirements

 

Equipment Design, Fabrication & Commissioning 

• Lead equipment scope for development rigs, pilot lines, and production lines, from P&IDs and layouts through detailed mechanical design
• Own fabrication oversight, factory acceptance testing (FAT), site acceptance testing (SAT), and equipment commissioning
• Drive scale-up from laboratory and pilot equipment to production throughput while preserving product specifications
• Establish equipment reliability, maintenance, and spare parts strategies that support high-uptime production
• Integrate with controls, instrumentation, and facility engineering on utilities, ventilation, off-gas, and process control interfaces

 

Program & Team Leadership 

• Build, lead, and mentor the fuel equipment engineering team across mechanical, process equipment, thermal, and design disciplines
• Define team structure, staffing plans, and competency roadmap as the program scales from development through production
• Manage equipment engineering scope, schedule, and budget within the broader fuel program
• Select and manage skid fabricators, furnace and reactor vendors, and component suppliers; define design, quality, inspection, and acceptance requirements
• Collaborate closely with fuel process engineering, quality, nuclear safety, licensing, facility engineering, and operations to keep equipment, process, and facility designs coherent

 

Basic Qualifications  

• 10+ years of engineering experience designing process equipment for chemical, materials, or high temperature manufacturing systems 

• 5+ years of experience managing engineering teams 

• Demonstrated hands-on experience with equipment similar to TRISO production equipment 

• Experience leading equipment lifecycle from design through to commissioning 

• Strong foundation in process equipment design principles, including pressure vessels, piping, gas delivery, heat transfer, materials selection, and effluent treatment 

• Experience scaling processes from pilot to production 

• Experience managing vendor relationships across multiple project phases 

• Important: Ability to travel and work onsite at Valar's pilot plant in Orangeville, Utah 20-30% of the time, for large periods of time (one to two weeks, or more). 

 

Preferred Skills and Experience

• Experience managing engineering teams in a start-up or high growth environment 

• Direct experience with TRISO or other coated-particle fabrication 

• Direct experience with Uranium conversion 

• Experience with fluidized-bed CVD, and precursors such as methyltrichlorosilane 

• Familiarity handling hazardous material, including gloveboxes, confinement, and nuclear criticality safety 

  

What We Offer  

• Competitive base salary 
• Equity ownership in a rapidly growing advanced energy company 
• Comprehensive medical benefits 
• Unlimited PTO
• Free daily lunch and dinner provided onsite 
• Generous PPE stipend
• High-impact startup environment with significant ownership and autonomy 
• Opportunities for rapid career growth and internal advancement 
• Direct collaboration with experienced operators, engineers, and industry leaders 
• The opportunity to help build and scale transformative energy technology from the ground up
