If you are searching for the best new ideas and share our vision, join us as a “Senior Mechanical Engineer - Welding and Remote Operations”. This is what you need to know: Location Knoxville, TN Salary Highly Competitive Plus Benefits Contract Permanent, full time Reporting to VP Stellarator Maintenance and Inspection Your role in the mission The Senior Engineer will play a pivotal role in the design, development, and implementation of complex mechanical systems and tooling solutions critical to our fusion energy programs. This role focuses on welding process and related tooling design in addition to remote operations/automation related to completing maintenance on components in a high radiation field. Ultimately our work supports maintenance, repair and overhaul of high‑precision manufactured and assembled fusion components. The ideal candidate is a hands‑on engineer with demonstrated experience developing weld tooling and/or welding processes plus designing automated or remotely operated mechanical systems. The successful candidate will contribute to both early‑stage design and detailed manufacturing support, bringing practical, scalable solutions to complex engineering challenges in extreme environments. This position requires a unique combination of technical fluency and project discipline. The ideal candidate will have deep familiarity with engineering development processes—particularly those involving mechanical systems, electrical integration, software and hardware controls—and will understand how to integrate those workflows within an EVM‑based project management framework. Ultimately, this role is pivotal to enabling our technical and programmatic success—ensuring that complex engineering efforts are delivered predictably, transparently, and in alignment with the company’s broader fusion energy development roadmap.

• Lead the design and integration of mechanical tooling, fixtures, and automated systems used for welding, assembly, and component handling.
• Develop and refine weld processes, including parameter optimization, sequence development, and validation for advanced materials and geometries.
