Mechanical Engineer (3915)

Position Summary

The Mechanical Engineer will support the design and development of custom high-temperature process equipment, including molten salt vessels, furnaces, and related thermal systems. This role will help translate process needs into manufacturable mechanical designs while coordinating with electrochemical, piping, electrical, controls, procurement, fabrication, and operations teams.

Responsibilities

• Design and support high-temperature molten salt vessels, furnaces, thermal equipment, fixtures, and custom process equipment.
• Develop mechanical design inputs, calculations, equipment specifications, drawings, design review packages, and fabrication support documentation.
• Evaluate materials, thermal expansion, sealing, insulation, support structures, maintainability, fabrication methods, and equipment interfaces.
• Coordinate mechanical design requirements with electrochemical systems, mechanical piping, electrical power, controls, instrumentation, and manufacturing teams.
• Support vendor coordination, fabrication oversight, inspection, installation, commissioning, troubleshooting, and design change resolution.
• Ensure mechanical designs support safety, quality, manufacturability, operability, maintainability, and project schedule requirements.

Requirements

• Experience with high-temperature mechanical equipment, molten salt vessels, furnace design, thermal systems, or similar industrial process equipment.
• Demonstrated experience with custom equipment design and fabrication, including development of practical designs that can be built, inspected, installed, and maintained.
• Strong mechanical engineering knowledge related to materials, pressure/thermal effects, structural supports, equipment interfaces, and design documentation.
• Ability to work effectively with multidisciplinary technical teams in a safety- and quality-driven engineering environment.
• Experience supporting design reviews, calculations, specifications, drawings, procurement, fabrication, or field implementation activities.

Preferred Qualifications

• Experience with molten salts, high-temperature corrosion considerations, refractory/insulation systems, or specialized furnace and vessel design.
• Experience in DOE, NNSA, nuclear, advanced energy, chemical processing, metallurgy, or highly regulated industrial environments.
• Professional Engineer registration, advanced mechanical design experience, or experience acting as a technical lead for custom equipment design is preferred.

Education and Experience

Bachelor's degree in Mechanical Engineering or a related engineering discipline is preferred. Equivalent combinations of education, technical training, and directly relevant high-temperature equipment design experience may be considered. Due to the nature of the government contract requirements and/or clearances requirements, US citizenship is required.

Benefits

• Health Care Plan (Medical, Dental & Vision)
• Retirement Plan (401k)
• Life Insurance (Basic, Voluntary & AD&D)
• Paid Time Off (Vacation & Public Holidays)
• Short Term & Long Term Disability
