The TeamAs 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 Sol-Gel Equipment owns the design of our sol-gel 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 sol-gel equipment and lead the engineers who build it.
This role is hands-on. You will design and build equipment for processes from dissolving through to casting and aging, while guiding a small team as the program scales from development to production.
Key Responsibilities Technical Leadership - Sol-Gel Equipment - Own the equipment design basis sol gel equipment, from receipt of Uranium to completed kernels
- Lead design of fluid distribution, process piping, casting columns, and aging/washing/drying process
- 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 equipment
- 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 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.
