Position Summary The Mechanical Designer will develop detailed mechanical design models, drawings, and fabrication-ready documentation for custom equipment and high-temperature process systems. This role requires strong SolidWorks capability, practical design-for-manufacturability experience, and the ability to work closely with engineers, fabricators, and project teams to convert technical concepts into buildable designs. Responsibilities Create and maintain detailed SolidWorks models, assemblies, drawings, bills of material, and fabrication documentation for custom mechanical equipment. Apply design-for-manufacturability principles to support practical fabrication, inspection, assembly, installation, operation, and maintenance of equipment. Support design development for high-temperature equipment, molten salt systems, furnace components, fixtures, piping interfaces, and related mechanical assemblies. Coordinate design details with mechanical engineers, piping engineers, electrical engineers, controls staff, procurement, vendors, and fabrication personnel. Revise drawings and models based on design reviews, constructability feedback, vendor input, field changes, and configuration-controlled updates. Maintain accurate technical documentation in accordance with project quality, safety, document control, and configuration management expectations. Advanced SolidWorks experience, including complex assemblies, detailed part modeling, fabrication drawings, drawing standards, and bills of material. Substantial design-for-manufacturability experience with custom equipment, fabricated assemblies, industrial systems, or process equipment. Ability to interpret engineering direction, calculations, sketches, specifications, and technical requirements and convert them into accurate design deliverables. Experience coordinating design details with engineers, fabricators, vendors, and multidisciplinary project teams. Strong attention to detail, documentation quality, revision control, and practical fabrication/assembly considerations. Preferred Qualifications High-temperature equipment design experience, including molten salt systems, furnace components, thermal equipment, specialty materials, or insulated assemblies. Experience supporting DOE, NNSA, nuclear, advanced energy, chemical processing, manufacturing, or highly regulated technical projects. Experience with drawing checking, tolerance review, weldments, sheet metal, machined parts, piping interfaces, or vendor fabrication packages. Education and Experience Associate degree, technical diploma, or equivalent training in mechanical design, drafting, CAD, engineering technology, or a related field is preferred. Equivalent combinations of education, technical training, and directly relevant SolidWorks/mechanical design experience may be considered.
