Job description

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 We're looking for a skilled Technical Illustrator and CAD Designer to join our engineering documentation team. You'll transform complex mechanical and electromechanical assemblies into clear, production-ready technical illustrations, work instructions, and 3D documentation that support manufacturing, service, and training operations. The ideal candidate is equally comfortable inside a CAD environment and an illustration workflow—someone who takes pride in visual clarity, understands how assemblies fit together, and can communicate complex technical information to both engineering and non-engineering audiences. The role requires strong familiarity with real-world manufacturing processes (machining, fabrication, and assembly) so that documentation accurately reflects how parts are actually made, finished, and verified on the shop floor. Candidates must also demonstrate strong working knowledge of GD&T per ASME Y14.5, the ability to identify and document drawing deviations, and experience revising drawings to meet ASME codes and regulatory requirements. Key Responsibilities Create detailed technical illustrations, exploded views, assembly sequences, and callout graphics. Develop and maintain work instructions usable on the shop floor, and produce installation guides and assembly procedures from 3D models. Use SolidWorks Composer (or equivalent) for technical illustrations. Create and modify 3D models and 2D drawings, generating drawings with proper GD&T and BOMs. Support prototype builds and documentation, and develop drawings reflecting CNC machining, lathe work, and fabrication. Incorporate tooling access, datum structure, and finishes into drawings, and collaborate with machinists and technicians on machined and pressure-containing hardware documentation. Document CNC milling, turning, and lathe processes, and define finishes, coatings, and heat treatments. Create documentation for sheet metal and welding, and support pressure vessel fabrication and testing (hydro, leak). Align documentation with inspection and tolerance requirements. Apply GD&T per ASME Y14.5, and review and revise drawings for compliance. Document deviations and corrective actions, and support pressure vessel documentation in accordance with ASME Section VIII. Basic Qualifications Associate's or Bachelor's degree in a related field. 2+ years of experience in CAD and technical illustration. Proficiency in SolidWorks or equivalent. Strong GD&T knowledge per ASME Y14.5. Experience with PDM and PLM systems. Ability to read and interpret engineering drawings. Understanding of CNC machining and lathe operations. Familiarity with sheet metal fabrication. Experience with coatings and finishes. Exposure to pressure vessel systems. Preferred Skills and Experience SolidWorks Composer experience. Aerospace or energy industry background. Experience with PLM tools such as Teamcenter or Windchill. Proficiency in Adobe Illustrator. Direct experience working with machine shops and understanding CNC workflows and machinability. Experience documenting weldments or pressure systems. 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 Equal Employment Opportunity Statement Valar Atomics is an equal opportunity employer. We consider all qualified applicants without regard to race, color, religion, sex, gender identity, sexual orientation, national origin, age, disability, veteran status, or any other protected status under applicable law. We are committed to providing a workplace free of discrimination and harassment and will provide reasonable accommodation as required by law.
