5-Axis CNC Machinist

We are seeking an experienced 5-Axis CNC Mill Machinist to join our aerospace and defense manufacturing team. This role is responsible for the setup, operation, and optimization of complex 5-axis milling centers to produce high-precision components that meet strict aerospace and defense quality standards. The ideal candidate has experience machining tight-tolerance parts from high-strength alloys and is comfortable working in a regulated manufacturing environment.

Responsibilities

• Set up and operate 5-axis CNC milling machines to manufacture complex aerospace components

• Interpret blueprints, models, and GD&T to ensure accurate setups and machining strategies

• Select, install, and qualify tooling, fixtures, and workholding for multi-axis operations

• Perform tool offsets and make real-time adjustments to maintain dimensional accuracy

• Edit and troubleshoot CNC programs (G-code / M-code) at the machine

• Optimize feeds, speeds, and toolpaths for 5-axis machining applications

• Utilize CAD/CAM software (Mastercam, Siemens NX, or similar) for toolpath verification and simulation

• Perform first-piece, in-process, and final inspections using micrometers, calipers, height gauges, and CMM

• Maintain tight tolerances common to aerospace components

• Identify and correct dimensional or surface finish discrepancies

• Perform preventative maintenance and basic troubleshooting on 5-axis milling centers

• Collaborate with engineering and quality teams to improve processes and reduce cycle times

• Follow all aerospace/defense quality standards and safety protocols

Qualifications

Education:

High school diploma or equivalent required. Technical certification in CNC machining or related field preferred.

Experience:

Minimum 3 years of 5-axis CNC milling experience required. Experience machining aerospace-grade materials such as aluminum, titanium, stainless steel, and high-strength alloys preferred. Background in aerospace, defense, or similarly regulated manufacturing environment strongly preferred. Familiarity with Fanuc and/or Fidia controllers is a plus.

You should be proficient in:

• CNC Machine Setup & Changeover

Machines & technologies you'll use:

• CNC Mill (3-4 axis VMC)
• CNC Mill (5 axis VMC)
