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 Role

The Maintenance Technician ensures safe, reliable, and compliant operation of the Valar Atomics TRISO Fuel Facility. The technician performs preventive and corrective maintenance on process equipment, instrumentation, and facility systems in a safety-critical, NRC/DOE-regulated environment. This is a mid-level role requiring 3–7 years of industrial maintenance experience; ideally in a nuclear, chemical, or advanced manufacturing setting.

Key Responsibilities

• Perform scheduled preventive maintenance on CVD coater furnaces, calcining furnaces, sintering furnaces, chemical systems, and AWD units per approved work orders.
• Replace consumable components: graphite heating elements, reactor tubes, cones, gas distributors, etc.
• Diagnose and repair faults on mechanical, electrical, and pneumatic systems; complete corrective work orders within defined response windows.
• Maintain gas feed systems including mass flow meters, gas lines, valves, and associated instrumentation (accuracy maintained to ±1 % FS).
• Perform maintenance on material-handling equipment; disassemble and reassemble for radiological safety compliance.
• Service the off-gas handling and combustion burner system; verify scrubber and absolute filter performance.
• Execute instrument calibration tasks; issue calibration certificates and maintain records per equipment data sheets and P&IDs.
• Interpret instrument loop diagrams and PLC ladder logic to support fault isolation; liaise with controls engineers on SCADA/OIS issues.
• Identify, order, and manage critical spare parts inventory (heating elements, pyrometers, seals, etc.).
• Work within the facility Radiation Protection and ALARA program; wear appropriate PPE and comply with contamination-control procedures.
• Support configuration management by documenting modifications and updating maintenance procedures as required.

• Responds promptly to unplanned equipment faults.
• Demonstrates ownership of equipment health and proactively identifies deterioration before failure occurs.

Basic Qualifications

• 3–7 years of maintenance technician experience in a nuclear, chemical process, or precision manufacturing facility.
• Demonstrated competency in mechanical systems: pumps, valves, gas lines, furnaces, and rotating equipment.
• Electrical and instrumentation skills: calibration, loop checking, 480 V industrial electrical systems.
• Ability to read and interpret P&IDs, instrument loop diagrams, wiring diagrams, and maintenance manuals.
• Familiarity with maintenance software for workorder creation and closure.
• Must be a U.S. citizen or U.S. person eligible to access HALEU material under DOE/NRC regulations.
• Strong written communication skills for procedure authoring and maintenance record-keeping.

Preferred Skills and Experience

• Experience maintaining CVD furnaces, high-temperature kilns, or gas-phase deposition equipment.
• Nuclear Maintenance qualification or radiological worker training.
• Experience with PLC-controlled process systems and OIS/SCADA interfaces (Allen-Bradley, Siemens).
• Familiarity with criticality safe geometry controls and ALARA work practices in uranium-processing environments.
