Job Summary

Responsible for performing precision setups and operations on multi-axis CNC milling and turning machines. In this role, you will prepare machines for production by installing tooling, fixtures, and programs, validating first-article parts, and ensuring parts meet strict quality and dimensional standards.

Qualifications

Essential Duties and Responsibilities

The duties and responsibilities described are not a comprehensive list and additional tasks may be assigned. To perform this job successfully an individual must be able to perform each essential duty satisfactorily.

Automation & Continuous Improvement

Collaborate with Programming and Manufacturing Engineers to optimize machining processes suitable for automation (robotic loading, in-process inspection & probing) to support lights-out manufacturing.

Apply continuous improvement principles to machining processes to improve efficiency, reduce lead times, and eliminate non-value-added activities.

Quality & Problem Solving

Diagnose machining issues, perform root-cause analysis, and implement sustainable corrective actions.

Ensure adherence to tight tolerances using advanced inspection tools and techniques.

Read and interpret GD&T, engineering drawings, and 3D part models to ensure precision manufacturing.

Training & Leadership

Develop and maintain detailed setup documentation, including setup sheets, tooling files, and manufacturing inspection plans.

Mentor and train less experienced machinists in setup techniques and process control.

Promote a culture of craftsmanship, accountability, and continuous improvement.

Qualifications, Experience and Education Requirements

High School diploma or equivalent

5+ years hands-on experience in CNC precision machining (aerospace, defense, or medical).

Expertise in G-code, canned cycles, and in-process probing systems.

Proven track record of machining tight-tolerance parts using aluminum, steel, and aerospace-grade alloys.

Understanding of metal behavior & mechanics in a machining environment (chip formation, vibration, distortion, heat transfer, etc.)

Understanding of cutting tool geometry, fixture design, and tool life management.

Ability to interpret GD&T and manufacturing drawings.

Proven ability to diagnose and resolve complex machining issues independently - from chatter and tool wear to dimensional instability and setup inefficiencies.

Experience with standard MS Office tools (Excel, Outlook)
