Tooling Design Engineer II-Senior

The role

This person will own the design, development, fabrication, and implementation of tooling and ground support equipment for Antares R1 microreactors. They will work with manufacturing, test, and deployment teams to translate hardware needs into practical engineering solutions.

What you will do

• Own the design, development, fabrication, qualification, and implementation of tooling and ground support equipment.
• Work with manufacturing, test, reactor hardware, operations, quality, and deployment teams.
• Develop tooling concepts from first principles.
• Create detailed 3D CAD models, assemblies, and engineering drawings.
• Perform mechanical design and basic engineering analysis.
• Design tooling with ergonomics, access, and maintainability in mind.
• Work hands-on with machinists, welders, technicians, suppliers, and engineers to fabricate and assemble tooling.
• Direct and support the initial use of new tooling on the factory floor and at deployment sites.
• Develop ground support equipment and handling solutions for reactor hardware.
• Support integrated reactor and subsystem testing by developing fixtures and test stands.

Required qualifications

• Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, Manufacturing Engineering, or a related technical discipline.
• 3+ years of experience designing mechanical hardware, tooling, fixtures, ground support equipment, manufacturing equipment, or similar systems.
• Strong 3D CAD skills and experience developing production-quality engineering drawings.
• Demonstrated ability to take mechanical designs from initial concept through detailed design, fabrication, assembly, and implementation.
• Experience designing hardware for practical use in manufacturing, assembly, test, installation, maintenance, or field operations environments.
• Strong understanding of mechanical design fundamentals, including tolerance stack-ups, fits, fasteners, structural loading, material selection, and design for manufacturing and assembly.
• Ability and willingness to support tooling installation, checkout, and operation in both factory and field environments.

Nice to have

• Experience designing ground support equipment (GSE), lifting and handling equipment, assembly fixtures, transportation fixtures, test stands, deployment equipment, or other specialized tooling for aer
• Proficiency with Siemens NX, including complex assemblies, detailed drawings, and configuration-controlled mechanical design.
• Experience designing tooling for large, heavy, high-value, or geometrically sensitive hardware.
• Experience with lifting and rigging equipment.
• Experience performing or reviewing structural calculations or finite element analysis.
• Experience supporting integrated hardware testing.
• Familiarity with common fabrication processes including CNC machining, welding, sheet metal fabrication, structural fabrication, additive manufacturing, and commercial off-the-shelf component selectio
• Experience commissioning new equipment on a production floor or at a field site.
• Experience working in a highly regulated or safety-critical industry such as nuclear, aerospace, spaceflight, defense, energy, or medical devices.
• Comfortable working in a fast-paced hardware development environment.
