Mechanical Engineer

ABOUT FUSE We are building one of the most potentially consequential companies of the century. Our mission is to accelerate the world's transition to fusion energy while safeguarding humankind. This is not a normal company. This is not a normal job. We are committed for the long term to win. ABOUT THE ROLE As a Mechanical Engineer at Fuse, you'll be responsible for end-to-end mechanical design of pulsed-power machines — from concept through detailed design, working directly with electrical, controls, and pulsed-power teams to turn requirements into hardware. You'll drive design reviews, keep drawing packages current, and stay hands-on through assembly as machines evolve through testing. CORE RESPONSIBILITIES Be responsible for end-to-end mechanical design of pulsed-power machines, from concept through detailed design across multiple subsystems. Gather and integrate requirements from electrical, controls, and pulsed-power teams into cohesive mechanical designs. Coordinate procurement and manufacturing, working directly with vendors and suppliers to ensure parts are produced to specification and on schedule. Drive design reviews, be responsible for the drawing package, and manage action items through rapid iteration cycles. Be hands-on during machine assembly, providing direct technical oversight and ensuring build intent is executed to specification. Oversee site work, ensuring procedures are followed correctly and fielding technical questions in real time. Support existing builds and lead design iterations as machines evolve through testing and development. MINIMUM QUALIFICATIONS Bachelor's degree in Mechanical Engineering or equivalent experience. 2+ years of experience with SolidWorks/Siemens NX and CAD modeling; internships count toward this requirement. Demonstrated experience working on a team and achieving a common goal. Ability to create detailed engineering drawings, assembly procedures, and reports, with proficient application of GD&T tolerancing practices
