Schedule:

Full-time;
Monday-Friday | 7:00am-3:30pm

• Gain hands-on experience with cutting-edge equipment, materials, and CAD/CAM tools.
• Take ownership of challenging setups and problem-solving that directly impact production success.
• Develop highly sought-after skills in tight-tolerance machining and multi-axis operations.
• Be part of a quality-driven environment where craftsmanship and technical expertise are valued.

• Setup and Operation:
  Configure complex setups for 5-axis vertical/horizontal mills and multi-spindle lathes. This includes mounting work pieces, aligning fixtures, and loading specialized tooling.
• Blueprint & GD&T Interpretation:
  Read and interpret intricate engineering drawings, CAD models, and Geometric Dimensioning and Tolerancing (GD&T) to plan machining sequences.
• Material Expertise:
  Machine high-performance, tough aerospace alloys such as Titanium, Inconel, and Stainless Steel, adjusting feeds and speeds to optimize tool life and surface finish.
• Quality Inspection:
  Conduct rigorous in-process and final inspections using precision tools like micrometers, calipers, and bore gauges to maintain tolerances often as tight as ±.001" or better.
• Troubleshooting & Programming:
  Perform basic G-code edits at the machine and resolve issues like tool wear, chatter, or controller alarms to minimize downtime.

• 3–8+ years of CNC machining experience, including 2–3 years in 5-axis setup and operation, with proficiency in advanced controllers (Fanuc, Siemens, Mazatrol, Heidenhain).
• Strong ability to interpret complex blueprints, CAD models, and GD&T, with hands-on experience machining high-performance aerospace alloys.
• Skilled in precision inspection and familiar with CAD/CAM software (e.g., Mastercam, Hypermill, Siemens NX) for quality control and toolpath optimization.

This role requires the ability to stand for extended periods, perform repetitive motions, and safely lift and position heavy materials or tooling. Candidates must have strong hand-eye coordination, manual dexterity, and the ability to work in a manufacturing environment with exposure to noise, machinery, and varying temperatures.

We are committed to fostering an inclusive workplace that welcomes diverse candidates. All qualified applicants will be considered regardless of background, identity, or status.
