Job description

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

The Manufacturing organization transforms engineering designs into high-quality products through precision manufacturing, disciplined execution, and continuous improvement. The team develops scalable production capabilities that support the commercialization of advanced nuclear technology.

The Role

Valar Atomics is looking for a Mechanical Technician to build up mechanical and electromechanical assemblies for our modular nuclear reactor systems. You will work primarily with hand and power tools to fit, fasten, and integrate a wide variety of components - from small precision sub-assemblies to larger structural builds - following engineering drawings and work instructions. This is a hands-on shop-floor role with a lot of variety, well suited to someone who enjoys figuring out how things fit together and go together correctly.

Key Responsibilities

• Assemble mechanical and electromechanical components using hand and power tools (wrenches, drivers, torque tools, etc.).
• Read and follow engineering drawings, work instructions, and bills of materials to complete builds correctly.
• Fit, fasten, align, and torque components to specification; verify fit-up and functionality before sign-off.
• Identify and troubleshoot assembly issues, fitment problems, or missing/incorrect parts, and elevate as needed.
• Maintain a clean, organized, and safe workspace; follow 5S and shop safety standards.
• Support a wide range of build types across different product lines and subassemblies as priorities shift.
• Document completed work, inspection results, and any non-conformances per quality procedures.

Basic Qualifications

• 4+ years of experience in mechanical assembly, maintenance, or a similar hands-on technical role.
• Strong proficiency with hand tools and basic power tools (torque wrenches, drills, drivers, etc.).
• Ability to read and follow engineering drawings, work instructions, and assembly procedures.
• Comfortable working across a variety of assembly tasks and switching between them throughout the day.
• Strong attention to detail and commitment to build quality.
• Comfortable working in a fast-paced startup manufacturing environment with evolving processes.
• Ability to lift up to 50 lbs, stand for extended periods, and work in a shop‑floor setting with appropriate PPE.

Preferred Skills and Experience

• Experience with mechanical assembly in aerospace, nuclear, automotive, or other highly regulated industries.
• Basic electrical or electromechanical assembly experience (wiring, connectors, harnessing).
• Familiarity with torque specifications, fastener standards, and basic hand‑tool calibration.
• Prior experience in a startup or low‑volume/high‑mix production environment.
• Forklift, overhead crane, or rigging certification.

What We Offer

• Equity ownership in a rapidly growing advanced energy company
• 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
