Machinist

The Machinist III independently sets up and operates advanced 3-, 4-, and 5-axis CNC machining centers to produce complex, mission-critical aerospace hardware. This role owns the machining process from initial setup through dimensional verification, frequently working on one-of-one and low-volume components made from difficult, high-value materials. The position requires advanced machining judgment, strong troubleshooting skills, and close collaboration with Programming, Engineering, and Quality teams, while also providing technical guidance to less-experienced machinists.

• Independently set up and operate complex 3-, 4-, and 5-axis CNC machining centers for precision aerospace components.
• Prove out setups for new or unproven components in collaboration with Programming and Engineering, ensuring safe and stable machining processes.
• Machine one-of-one, prototype, and low-volume flight hardware using Inconel, titanium, stainless steel, copper, and other exotic alloys.
• Perform conversational programming and controller-level G-code and M-code edits using Fanuc and/or Siemens controls.
• Install and qualify fixtures, workholding, cutting tools, probes, machine datums, and related setup components to support accurate machining.
• Interpret engineering drawings, 3D models, setup documentation, and Geometric Dimensioning and Tolerancing (GD&T) requirements to produce conforming parts.
• Perform first-piece and in-process dimensional verification while monitoring tool wear, machining conditions, and process stability.
• Independently troubleshoot machining, tooling, setup, and dimensional issues in partnership with Programming, Engineering, and Quality.
• Exercise stop-work authority when conditions may place personnel, equipment, or hardware at risk, prioritizing safety and product integrity.
• Provide technical guidance and mentorship to less-experienced machinists, sharing best practices and supporting skill development.
• Read and interpret blueprints and mechanical drawings to plan machining operations and changeovers effectively.
• Operate CNC and related machine tools, performing changeovers and adjustments to maintain productivity and quality.
• Apply strong mechanical aptitude and troubleshooting skills to address equipment, shear, and machine operating issues as they arise.

• High school diploma or equivalent.
• 5+ years of CNC machining experience in a precision manufacturing environment.
• Proven ability to independently set up and operate complex 3-, 4-, and 5-axis CNC machining centers with minimal supervision.
• Experience machining one-of-one, prototype, or low-volume, high-value components.
• Experience machining Inconel, titanium, stainless steel, copper, and other exotic alloys.
• Conversational programming experience using Fanuc and/or Siemens controls.
• Basic CAM experience using Mastercam, ESPRIT, CATIA, or comparable software.
• Experience working within an AS9100 or equivalent quality management system.
• Strong blueprint-reading skills and practical knowledge of GD&T.
• Strong knowledge of cutting tools, workholding, fixturing, probing, feeds, and speeds.
• Proficiency using precision measuring and inspection equipment for dimensional verification.
• Ability to exercise sound judgment and maintain composure while machining one-of-one and high-value aerospace hardware.
• Strong verbal and written communication skills.
• Demonstrated mechanical aptitude with hands-on machine operation and changeover experience.
• Solid troubleshooting skills for machining processes, tooling, and mechanical issues.

• Experience with large-format 5-axis machining.
• Experience machining additively manufactured components.
• Previous experience mentoring or providing technical guidance to less-experienced machinists.
• Advanced experience troubleshooting complex machining, tooling, dimensional, and process-related issues.
• Familiarity with shear and other metalworking equipment in a machine shop environment.
• Comfort working with advanced mechanical systems and CNC machine controls.
• Ability to collaborate effectively with cross-functional teams including Programming, Engineering, and Quality.

The organization offers opportunities for both local and traveling professionals who are seeking long-term engagement in a high-impact aerospace manufacturing environment. You can work with cutting-edge machining technology and complex, mission-critical hardware while collaborating closely with skilled engineering and quality teams. The culture values technical excellence, safety, and continuous improvement, providing room to grow your expertise, share your knowledge, and take ownership of challenging projects.

This role is based in a machine shop environment that focuses on precision aerospace manufacturing. You will work around CNC machining centers and related metalworking equipment, with some exposure to noise, dust, and machine shavings typical of an active production floor. The facility is equipped with advanced controls and inspection tools to support high-quality work. Appropriate shop attire and adherence to standard safety practices are expected to ensure a safe and professional workplace.
