• Perform setups, establish work and tool offsets, and adjust speeds and feeds.
• Edit or create G-code programs for process optimization.
• Read and interpret blueprints, including GD&T symbols and 3D part features.
• Troubleshoot surface finish, tool wear, or dimensional issues.
• Maintain machine cleanliness, perform minor maintenance, and ensure safe operation.
• Collaborate with lead machinists, engineers, and quality inspectors to ensure part accuracy.

Position Requirements:

• High School Diploma or equivalent.
• Strong attention to detail and mechanical aptitude.
• Basic understanding of CNC machining processes (training provided for entry-level).
• Familiarity with measurement tools and shop math.
• Ability to read and interpret blueprints and follow written instructions.
• Willingness to learn setup, programming, and inspection techniques.
• Preferred Qualifications:
• 3–10 years of CNC machining experience (mills and/or lathes).
• Skilled in full setups, offsets, and tool selection.
• Experience with G-code edits, live tooling, or multi-axis machining.
• Knowledge of materials such as aluminum, stainless, and hardened steels.
• Proficiency in blueprint reading, GD&T, and precision measuring equipment.
• Familiarity with CAM programming software (Mastercam or similar) a plus.
• Leadership or training experience welcomed.
• Work Environment & Physical Requirements:
• Standing for extended periods while operating grinding machines.
• Frequent lifting (up to 25 lbs.), bending, and handling of precision components.
• Exposure to coolant, grinding dust, and high-noise environments (PPE provided).
• Working with high-speed rotating equipment requires focus and adherence to safety protocols.
