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.\nThe Team\nThe Numenor team is building Valar’s next reactor, the flagship program that will define how we deliver nuclear power at scale. This dedicated team owns the entire plant, from the reactor core and helium systems to cooling, plant modules, and the Citadel, uniting mechanical, systems, safety, IC&E, quality, and supply chain under one mission. The work starts with bringing the first unit to life and ends with a production line that delivers reactors faster with every build. What this team builds will power the critical infrastructure of the future.\nThe Role\nValar Atomics seeks an Engineering Manager for the reactor program. This role will build and lead a team of Responsible Engineers and designers for a group of mechanical systems, either the reactor side (reactor core and graphite, control rod drives, helium pressure boundary, heat transport, cavity cooling, and helium services) or the plant side (power conversion, heat rejection, the reactor complex and Citadel, service modules, and plant services). The role will lead the team from the first unit through scaled production, delivering reactors at an increasing rate.\nThe role demands someone who leads engineers hands-on with a hardware-first mentality, owning people, schedule, and delivery, while the Responsible Engineers keep technical signature and ensure the design basis is met. We are looking for someone who obsessively removes blockers for the team every day, so the Responsible Engineers can focus on engineering and delivering functional systems.\nKey Responsibilities\nTeam Leadership\nHire, onboard, and mentor the Responsible Engineers, engineers, and designers for your group of systems.\nSet workload and priorities for the team, and remove blockers so it can move as fast as possible.\nManage scope, schedule, and budget for your systems within the reactor program.\nRun performance, growth, and staffing for the team as the program scales.\nDelivery\nOwn schedule and delivery for each system, from design through IFC, build, and test.\nTrack RE deliverables against each system’s baseline and raise slips early to the Director and program controls.\nCoordinate each system’s readiness for design reviews, design freeze, and IFC.\nIntegration\nDrive interface closure between systems with systems engineering and the plant model.\nWork closely with procurement and supply chain so parts and vendors arrive on time.\nWork with licensing, quality, safety, IC&E, and manufacturing so the design builds right the first time, and faster with each unit.\nBasic Qualifications\n5+ years of mechanical engineering on complex hardware, such as pressure systems, heat transfer equipment, mechanisms, or large structures.\n3+ years managing engineers with direct reports.\nDelivered hardware from design through build and test against a schedule.\nLed mechanical systems on first-of-a-kind hardware from concept through build, test, and commissioning.\nStrong base in mechanical design, drawings, analysis, and design reviews.\nExperience managing vendors and key suppliers through design and fabrication.\nComfortable working hands-on with the team on the shop floor and with vendors.\nPreferred Skills and Experience\nExperience with high-temperature, high-pressure systems, such as pressure vessels, heat exchangers, and piping.\nHardware delivery: first-of-a-kind hardware taken from design through build and test, in aerospace, power generation, oil and gas, or defense.\nHelium or other gas systems, precision mechanisms, or rotating equipment.\nPower conversion, heat rejection, or balance of plant, including skids and modular systems built in a factory and installed on site.\nWorking knowledge of ASME pressure vessel and piping codes (Section VIII, B31.1, B31.3).\nDesign for manufacture and scaling from prototype to series production.\nNuclear industry experience: commercial, defense, or national laboratory. A plus, not a prerequisite.\nPE license (Mechanical): a plus.\nWhat We Offer \nCompetitive base salary \nEquity ownership in a rapidly growing advanced energy company \nComprehensive medical benefits \nUnlimited PTO\nFree daily lunch and dinner provided onsite \nGenerous PPE stipend\nHigh-impact startup environment with significant ownership and autonomy \nOpportunities for rapid career growth and internal advancement \nDirect collaboration with experienced operators, engineers, and industry leaders \nThe opportunity to help build and scale transformative energy technology from the ground up\nEqual Employment Opportunity Statement\nValar Atomics is an equal opportunity employer.
