• Support capital equipment projects, including equipment justification, process planning, installation, programming, runoff, and production implementation.
• Assist with machine capability studies, process improvements, and corrective actions related to machining processes.

Documentation and Data Management

• Create and maintain standardized operating procedures, setup documentation, tooling information, and other manufacturing process documentation.
• Maintain CNC programs and associated documentation under appropriate revision control.
• Maintain manufacturing data including drawing revisions, part weights, cycle times, and other process information within Microsoft Access and departmental systems.
• Ensure programming and manufacturing documentation accurately reflects current production processes and adheres to current programming standards.

Production and Team Support

• Prioritize programming workload to support daily production requirements, new product launches, engineering changes, and department priorities.
• Work effectively both independently and as part of cross-functional teams.
• Provide technical support and mentorship to machinists and production employees.
• Assist with machining-related training and employee development initiatives.
• Communicate effectively with operators, machinists, engineering, quality, leadership, and customers.
• Maintain a clean and organized work area and support 5S initiatives.
• Follow all company policies and procedures related to safety, quality, and operational excellence.
• Perform other duties and special projects as assigned.

Qualifications

Required

• High school diploma or equivalent.
