• Strong troubleshooting and root cause analysis skills.
• Ability to manage multiple priorities while supporting production schedules.
• Excellent analytical, organizational, and problem-solving skills.
• Strong verbal and written communication skills with the ability to effectively communicate across engineering, operations, and manufacturing teams.
• Demonstrated commitment to continuous improvement using Lean Manufacturing methodologies.

• Associate degree or higher in Mechanical Engineering, Manufacturing Engineering, Industrial Engineering, Engineering Technology, or a related technical field preferred.
• Equivalent combination of education, technical training, and relevant experience will be considered.

• Minimum of 5 years of CNC programming experience in aerospace, precision machining, or other highly regulated manufacturing environments.
• Experience programming multi-axis CNC equipment including turning and milling centers.
• Demonstrated experience designing tooling and fixtures for complex machining applications.
• Experience supporting new product introductions, process validation, and production improvements.
• Experience implementing machining process improvements resulting in measurable reductions in tooling costs, cycle times, scrap, or downtime.
• Experience supporting ERP systems and engineering documentation preferred.
