ABOUT THE ROLE

The Manufacturing Engineer will lead and support continuous improvement initiatives (KAIZEN), troubleshoot production issues, and drive engineering excellence across plastic extrusion operations. This role is critical in launching new programs from contract award through SOP, optimizing extrusion processes, and implementing changes driven by Engineering Change Instructions (ECIs) or lean manufacturing efforts. We are seeking a skilled Manufacturing Engineer to join our dynamic team. The ideal candidate will possess a strong foundation in engineering principles, plastic extrusion, and a passion for innovative design and problem-solving. This role involves working on various projects, utilizing advanced engineering tools and methodologies to develop efficient solutions that meet industry standards.

RESPONSIBILITIES

• Provide hands-on support for plastic extrusion lines, ensuring optimal performance and minimal downtime
• Troubleshoot and resolve extrusion-specific quality and process issues, collaborating with operators and quality teams
• Design and implement poka-yoke systems tailored to extrusion defects and dimensional tolerances
• Develop and maintain standard operating procedures (SOPs) and technical documentation for extrusion processes
• Create and modify PLC and HMI programs to enhance extrusion line automation and control
• Collaborate with tooling and maintenance teams to manage perishable tooling inventory and crib requirements
• Lead PFMEA reviews and drive annual Risk Priority Number (RPN) reductions for extrusion processes
• Interface with the Quality department to address customer complaints, root cause analysis, and corrective actions
• Support ECI-driven changes and continuous improvement projects across extrusion and downstream operations
• Work with Industrial Engineering to define cycle times, Yamazumi charts, and labor requirements for extrusion cells
• Conduct DOE (Design of Experiments) and process validations for new extrusion tooling and materials
• Monitor and improve material flow, die design, cooling profiles, and puller calibration to ensure consistent product quality
• Participate in cross-functional teams to support SNA Continuous Improvement and lean manufacturing goals
