Job Description Job Description Description: PacAero Agawam is seeking a highly skilled CNC Process Engineer with strong Mastercam programming experience, hands-on CNC setup expertise, and a passion for process optimization. This role is responsible for developing, implementing, and improving machining processes for high-precision aerospace components. The ideal candidate will have solid experience with Okuma 5-axis and Haas vertical machining centers, with the ability to program, prove-out, and optimize machining operations in a fast-paced aerospace environment. This position is full-time onsite, Monday–Friday. Requirements: Process Engineering & CNC Programming • Develop CNC machining programs and produce NC code in Mastercam for complex aerospace components. • Select cutting tools best suited for materials, geometry, and tolerance requirements. • Create and maintain detailed setup sheets, operation-specific prints, and inspection criteria (process control documents). • Thoroughly document all manufacturing processes for repeatability and future use. • Perform research and development machining projects as assigned by the Machine Shop Manager. • Help develop new ideas to increase productivity, improve quality, and reduce rejects. Hands-On Setup, Operation & Troubleshooting • Set up CNC milling machines (multi-axis) and complete first-piece runs, including first-piece inspections. • Operate CNC milling machines for prototype and production runs, performing required in-process inspections. • Use precision inspection equipment to verify every part meets dimensional and quality requirements. • Troubleshoot machining, tooling, and process issues to ensure maximum uptime and part quality. • Support machine operators when questions or problems arise. Tooling, Fixtures & Equipment • Select, specify, and manage cutting tools and holders optimized for aerospace materials. • Maintain tool inventory levels and collaborate with Purchasing to ensure availability and cost control. • Evaluate new tooling technologies, vendors, and strategies to improve performance, reduce cost, and enhance tool life. • Establish and maintain standardized tool libraries and Mastercam toolpath templates to improve consistency and repeatability. • Design and manufacture required fixtures for machining and assembly operations. • Maintain standardized tool management systems and documentation. • Perform routine maintenance on CNC machine tools as needed. • Ensure machining processes enable unattended or lights-out machining whenever possible. Quality & Compliance • Ensure all machining operations comply with AS9100 and customer-specific aerospace requirements. .• Maintain proper documentation, traceability, and revision control. • Collaborate with Quality Assurance to address nonconformances and implement corrective actions. • Follow all company safety requirements when working with cutting tools, fixtures, and CNC machinery. • Keep the Machine Shop Manager informed of issues that could impact quality, productivity, or delivery. Cross-Functional Collaboration & Communication • Work closely with machinists, supervisors, engineers, and quality inspectors to resolve technical challenges. • Provide technical support during program prove-outs and machine operator training. • Attend or conduct meetings as required to support planning, improvement, and problem-solving. • Perform any additional duties assigned by the Machine Shop Manager. QUALIFICATIONS: • Minimum 5 years of CNC machining or programming experience in aerospace or high-precision manufacturing. • Strong experience programming with Mastercam (multi-axis milling). • Hands-on CNC setup experience, preferably on Okuma 5-axis and Haas vertical mills. • Strong understanding of GD&T, blueprint reading, and aerospace documentation standards. • Familiar with AS9100 quality system requirements. • Proficient with precision inspection tools and methods. • Excellent problem-solving, communication, and organizational skills. SKILLS, KNOWLEDGE, AND ABILITIES: • Skilled in fixture design, tool selection, and machining strategy optimization. • Experience with Okuma OSP controls and G-code editing. • Familiarity with lean, 5S, or Six Sigma methodologies. • Ability to thrive in a high-mix, low-volume aerospace environment with tight tolerances. • Strong analytical thinking and process-oriented mindset. PHYSICAL REQUIREMENTS AND WORKING CONDITIONS: • Climate-controlled precision machine shop. • Frequent standing, walking, and lifting up to 50 lbs. • Close collaboration with engineers, programmers, machinists, and inspectors to meet mission-critical aerospace standards.
