Why This Job Is Worth Considering

The Fabrication Engineering Group builds the hardware behind national security research programs — one-off and short-run prototypes with no existing playbook.

It's a senior hands-on role with real influence over how the shop runs, backed by the resources of an established federally funded national security research center.

What You'll Be Doing

• Program, set up, and operate CNC milling and turning equipment
• Maintain machine tools and shop equipment
• Own quality and adherence to tolerances and specifications on your work
• Keep your workspace organized and safe
• Collaborate with engineers on complex prototype development
• Mentor less experienced machinists
• Contribute ideas for shop efficiency improvements
