The Lead Mechanical Design Engineer role focuses on designing and optimizing piping and mechanical systems for process-control environments handling liquids or gases. Key responsibilities include leading facility piping design, performing complex fluid dynamics and structural analyses using CFD and FEA tools, and managing project phases from conception to realization. The position also involves mentoring junior engineers, ensuring regulatory compliance, and coordinating with stakeholders. This opportunity appeals to candidates seeking to drive innovation in highly regulated industries like nuclear or chemical processing. The role offers a chance to work on significant projects with minimal supervision while contributing to safety and continuous improvement. Successful candidates must be eligible for a Q security clearance, and the position is based on-site with potential travel for project coordination.
