Mechanical Engineer (PE) - Paducah
General Matter enriches uranium. We are designing, building, and operating the world’s lowest-cost enrichment services in the US. Our mission is to restore America’s ability to produce nuclear fuel to power AI, advanced manufacturing, and critical industries, making nuclear energy the cleanest, safest, and most affordable source of baseload power. We believe abundant nuclear energy will lead to a post-scarcity society. Backed by top venture capital firms and incubated inside Founders Fund, we are a lean, world-class team applying a first-principles approach to nuclear fuel production. Our culture is mission-driven, with a focus on urgency, accountability, and transparency.
About the role
As a Mechanical Engineer, you will play a pivotal role in executing a state-of-the-art enrichment facility from concept through commissioning. You will design, analyze, and ensure mechanical designs meet regulatory requirements for safety, performance, and compliance. This greenfield project offers the opportunity to collaborate with structural engineers, electrical engineers, architects, and both internal and external partners to develop detailed mechanical designs and specifications. You will wear multiple hats, supporting design work through vendor activity and troubleshooting, solving complex problems at scale in a dynamic environment.
Responsibilities
- Own design and analysis of mechanical systems including HVAC systems, central plant design (chillers, boilers, heat exchangers), and distribution sizing (ductwork, piping).
- Prepare design packages up to Permit level in Revit.
- Collaborate with structural, architectural, electrical, and chemical engineers to design and integrate safe and performant mechanical solutions.
- Prepare and review code-compliant designs up to permit level, create comprehensive drawing sets (Revit/AutoCAD), and produce calculations, specifications, and technical reports for design validation.
- Contribute to project concept development, feasibility studies, and scope definition, delivering mechanical solutions that meet performance, cost, and schedule goals.
Requirements
- Bachelor's degree in mechanical engineering or similar discipline.
- 8+ years of industry experience.
- Professional Engineer (PE) license is required.
- Experience working with HVAC systems.
- Proficiency in AutoCAD, Revit, and Bluebeam.
- Ability to work extended hours and weekends as necessary.
Skills
