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 Lead Engineer for Fluidized Bed CVD Coating Equipment owns the design of our coater systems end to end: from skid design through fabrication, factory and site acceptance testing, commissioning, and handover to fuel production operations. Reporting to the Director of Fuel Equipment Engineering, you will be the technical authority for coating equipment and lead the engineers who build it.
This role is hands-on. You will design and build high-temperature fluidized bed reactors, precursor gas delivery, and off-gas treatment, while guiding a small team as the program scales from development to production.
Key Responsibilities
Technical Leadership – CVD Coating Equipment
Own the equipment design basis for fluidized bed CVD coaters, from particle loading through unloading of coated particles
Lead design of coater vessels, gas distribution, heating systems, insulation, off-gas ventilation, and soot-handling
Lead design of precursor gas delivery for acetylene, propylene, methyltrichlorosilane, hydrogen, and argon, including mass flow control
Partner with process engineering and I&C team to translate fuel parameters into equipment requirements and control philosophy
Equipment Design, Fabrication and Commissioning
Develop P&IDs, layouts, and detailed designs for development and production coaters
Oversee factory acceptance testing and on-site commissioning activities
Lead troubleshooting and root cause investigations for equipment reliability issues
Establish maintenance, spare part, and consumable strategies for 24/7 operation
Team and Vendor Leadership
Lead and mentor a team of mechanical and equipment engineers
Manage coating equipment schedule, scope, and budget within the fuel equipment program
Select and manage suppliers and partners for key components
Collaborate closely with leadership across fuel process, I&C, quality, and operations.
Basic Qualifications
7+ years of experience designing CVD, fluidized bed, or other high-temperature gaseous process equipment
2+ years leading engineers as either a technical lead or a people manager
Hands-on experience taking process equipment from design to deployment
Experience with vessels, gas delivery, material selection, and off-gas treatment
Experience working safely with flammable, toxic, or corrosive process gasses
Important: Ability to travel and work onsite at Valar's pilot plant in Orangeville, Utah 20-30% of the time, sometimes for long periods of time (one to two weeks or more).
Preferred Skills and Experience
Direct experience with coated-particle equipment design
Familiarity with fissile material criticality safety requirements
Experience with Balance of Plant design for hazardous process gasses
Experience with silicon carbide deposition, including MTS-based processes
Previous history working with fluidization engineering or particle handling
Experience in a start-up or high growth environment
