Full job description
Requisition Id 16848
Overview:
We are seeking a Mechanical Design Engineer who will focus on conceptualization, design, build, and deployment of Electromagnetic Isotope Separation (EMIS) devices through the creation of sophisticated 3D CAD models and detailed design packages suitable for fabrication. This position resides in the Plasma Enrichment Deployment & Engineering Group in the Plasma Enrichment Science & Engineering Section, Enrichment Science & Engineering Division, Isotope Science & Engineering Directorate, at Oak Ridge National Laboratory (ORNL).
ESED stands at the forefront of the nation’s isotope mission—serving as the national steward for the research, development, and demonstration of enrichment technologies. At ORNL, we are internationally recognized leaders in electromagnetic enrichment technology, with a proud legacy dating back to the late 1940s. We are also the trusted stewards and dispensers of the nation’s stable isotope inventory, playing a critical role in enabling scientific discovery, innovation, and national capability.
Our division delivers end-to-end expertise across the entire enrichment process—from the chemical synthesis of feed materials to the fabrication of highly customized physical forms designed to meet the unique needs of diverse user communities. This integrated capability makes our work both technically distinctive and nationally important.
As part of our team, you will collaborate with a dedicated group of scientists, technicians, and engineers tackling complex, fast-paced technical challenges in support of the DOE Isotope Program. This rapidly growing program at ORNL offers exceptional opportunities for professional development, hands-on impact, and technical leadership. Our team is energized by the significance of the work, driven by innovation, and committed to developing creative solutions to some of today’s most pressing technology and process challenges. Success in advancing isotope separation technologies demands precision, ingenuity, and a relentless focus on both design excellence and the safety of our people and equipment.
This is an exciting time to join a rapidly growing program with strong opportunities for professional growth, innovation, and meaningful contribution. We’re looking for people who bring creativity, attention to detail, and a strong commitment to technical excellence, safety, and a positive team-focused culture.
Major Duties/Responsibilities:
Conceptualize, design, develop and improve plasma-based enrichment technology related components using 3D Computer Aided Design (CAD) software (SolidWorks).
