• Minimum of 9+ years of relevant experience in mechanical or facility design.
• Minimum of 5+ years of experience with facility design, including piping, ventilation, HVAC, gloveboxes, and related systems.
• Demonstrated experience supporting piping and mechanical system design for industrial, manufacturing, energy, chemical, or nuclear facilities.
• Hands-on experience with piping design and mechanical engineering for facility utilities and process systems.
• Experience with HVAC system design and ventilation systems for industrial or nuclear environments.
• Familiarity with engineering drawings, P&IDs, piping layouts, and mechanical design documentation.
• Knowledge of applicable industry codes and standards relevant to piping, mechanical, and nuclear or industrial facilities.
• Ability to review and perform engineering calculations, including pipe stress analysis, hydraulic calculations, safety valve sizing, and ventilation sizing.
• Ability to coordinate effectively with multidisciplinary engineering teams, including process, structural, electrical, and I&C disciplines.
• US citizenship.
• Ability to acquire and maintain a security clearance.

• Professional Engineer (PE) license preferred.
• Experience supporting DOE, NNSA, Naval Reactors, or commercial nuclear projects is preferred.
• Experience with 3D modeling or CAD tools such as AutoCAD Plant 3D, CADWorx, SolidWorks, CREO, or similar software is preferred.
• Experience with analytical software such as pipe stress analysis tools, hydraulic analysis tools, MathCAD, or MATLAB is preferred.
• Experience with commissioning activities and support of startup and testing is a plus.
• Strong ability to participate in design reviews and contribute to the resolution of complex technical issues.
• Effective communication skills for interfacing with clients, vendors, subcontractors, and internal project stakeholders.
• Strong organizational skills to support project planning, procurement, construction, and commissioning activities.

The role is based in an office environment with the option to work in a remote or hybrid arrangement, depending on project needs. You will work closely with multidisciplinary engineering teams and use modern engineering tools, including 3D CAD platforms such as AutoCAD Plant 3D, CADWorx, SolidWorks, and CREO, as well as analytical software for pipe stress and hydraulic analysis. The position involves both desk-based design work and occasional field walkdowns to verify piping and mechanical systems.
