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 \nAs part of the Engineering organization, Mechanical Engineering designs and develops the mechanicalsystems, components, and equipment that power Valar's advanced nuclear technologies. The teamensures designs are robust, manufacturable, and optimized for long-term performance.\nThe Role \nThe Mechanical Technician builds, tests, and commissions pressurized process gas skids for our advanced nuclear reactor. The work spans tube bending, piping, compressors, chillers, heat exchangers, and pressure vessels, from first fit-up through leak testing, pressure testing, and startup. You will maintain high standards for quality, safety, and workmanship and partner closely with engineering to turn designs into reliable, buildable hardware. \nKey Responsibilities \nBuild and test process system skids in accordance with approved drawings, specifications, procedures, and work instructions; work independently and coordinate with other technicians to support the build schedule. \nMaintain high standards for safety, workmanship, cleanliness, and procedure adherence throughout tube bending, fitting makeup, bolted joint assembly, testing, and commissioning activities. \nWork closely with engineering, quality, and operations; review drawings and procedures for buildability and raise drawing discrepancies, design conflicts, or unsafe conditions early. \nBuild process system skids to P&IDs, isometric and general arrangement drawings, specifications, and work instructions.\nMeasure, bend, cut, debur, and install stainless steel and alloy tubing; make up and inspect compression fittings with gap gauges per the manufacturer's \ninstructions. \nInstall and fit up piping, flanges, valves, regulators, relief devices, filters, and pressure vessels; assemble flanged joints with correct gaskets and controlled torque sequences (ASME PCC-1). \nInstall, align, and connect compressors, pumps, chillers, coolers, and heat exchangers, and coordinate instrumentation installation with electrical and I&C technicians. \nMaintain cleanliness and foreign material exclusion (FME) controls for high-purity gas service, and rig and move skids and equipment safely using cranes, hoists, and forklifts. \nPerform hydrostatic and pneumatic pressure tests per ASME B31.3, BPVC Section VIII, and approved test procedures. \nParticipate in mechanical completion walkdowns, punch lists, and system turnover, and support commissioning and startup of compressors, chillers, heat exchangers, and control and relief valves. \nDiagnose mechanical problems such as leaks, vibration, and overheating, and perform preventive and corrective maintenance to minimize downtime. \nMaintain tools, calibrated test equipment, and parts inventory, and participate in incident investigations and continuous improvement of build and test processes.\nBasic Qualifications \nHigh school diploma or equivalent. \n4+ years of hands-on mechanical experience in a process plant, chemical plant, power generation, or similar industrial environment, with significant work on pressurized gas systems. \nHands-on experience bending and installing stainless steel tubing and making up compression fittings to manufacturer standards. \nExperience assembling piping, flanges, valves, and vessels, including bolted joint assembly to specified torque values. \nExperience performing hydrostatic and pneumatic pressure tests and leak tests on high-pressure systems. \nExperience installing and maintaining compressors, pumps, and chillers, and heat exchangers.\nAbility to read and interpret P&IDs, isometric drawings, mechanical drawings, specifications, and procedures. \nProficiency with hand and power tools, torque tools, and precision measuring instruments. \nStrong working knowledge of safe practices for stored energy and pressurized systems, including lockout/tagout. \nStrong troubleshooting skills, attention to detail, and clear written and verbal communication. \nAble to lift up to 50 lbs unassisted, stand for extended periods, and work in confined spaces, at heights, and in required PPE. \nWilling to work extended hours, weekends, and shifts as needed to support build and test schedules. \nPreferred Skills and Experience \nCompletion of a trade school, apprenticeship, or military technical training program, or a bachelor's degree in mechanical engineering technology or a related field. \nWorking knowledge of ASME B31.3, BPVC Section VIII, and PCC-1; familiarity with ASME Section III is a plus. \nExperience with helium, hydrogen, nitrogen, CO2, or other high-purity process gas systems, including vacuum and cryogenic service. \nManufacturer tube fitting and tube bending training (for example Swagelok or Parker).\nJourneyman pipefitter, steamfitter, or millwright card.\nOrbital or manual GTAW tube welding experience, or experience working closely with welders on fit-up and inspection. \nRigging, crane signaling, and forklift qualifications\nExperience writing or redlining work instructions and test procedures.\nExperience in a fast-paced startup or first-of-a-kind build environment.\nWhat We Offer \nCompetitive base salary \nEquity ownership in a rapidly growing advanced energy company \nComprehensive medical benefits \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.
