• Design and implement jigs, fixtures, molds, and process aids to ensure repeatability, ergonomics, and operator safety.
• Support new product introductions (NPI) by creating process plans, routing steps, and tooling to enable smooth transition from prototype to production.
• Ensure processes comply with applicable quality and engineering standards (e.g., aerospace, defense, industrial specifications).
• Lead and participate in continuous improvement initiatives focused on scrap reduction, cycle time improvement, and yield enhancement.
• Conduct time studies, workflow analysis, and root cause investigations to eliminate waste and resolve bottlenecks.
• Apply Lean Manufacturing and Six Sigma methodologies (5S, DMAIC, value stream mapping) to improve key manufacturing KPIs.
• Develop, standardize, and maintain work instructions aligned with current processes.
• Support Engineering Change Orders (ECOs), ensuring accurate implementation of manufacturing documentation and routings.
• Collaborate with design engineering to evaluate manufacturability during product development and design reviews.
• Maintain up-to-date manufacturing documentation, including work instructions, process flows, and PFMEAs.
• Collect, analyze, and interpret manufacturing data to identify trends and improvement opportunities.
• Perform statistical analysis (SPC, DOE) to validate process capability and reduce variability.
• Support development of data visualization tools (e.g., Power BI, Grafana) for real-time performance monitoring.
• Identify and support implementation of automation opportunities in composite manufacturing processes.
• Collaborate with internal and external partners on automation integration and process control technologies.
• Support development and maintenance of IIoT-enabled monitoring systems.
• Partner with Quality Engineering to perform root cause analysis and implement corrective and preventive actions (CAPA).
• Develop and validate process controls to prevent non-conformances.
• Participate in MRB activities and provide technical input on non-conforming material disposition.
• Perform additional duties as assigned.
• Uphold Polygon’s Core Values: Safety, Deliver Quality, Initiative, Collaboration, and Innovation.

Education & Training

• Bachelor’s degree in Manufacturing Engineering, Mechanical Engineering, Industrial Engineering, Materials Engineering, or a related field.
• Experience in composite materials and processes (e.g., prepreg lay-up, resin infusion, autoclave, curing) strongly preferred.
• Industry certifications such as Lean Six Sigma Green Belt, Certified Manufacturing Engineer (CMfgE), or Composite Manufacturing certification are a plus.

Knowledge & Experience

Priority Experiences:

• Minimum of 2-5 years of hands-on manufacturing engineering experience in a composite or advanced materials environment.
• Proven ability to improve production processes through Lean and Six Sigma tools.
• Experience supporting cross-functional teams in a project-based environment.
• Familiarity with composite tooling design, curing processes, and material handling best practices.

Core Role Knowledge:

• Strong understanding of composite manufacturing methods, including hand lay-up, vacuum bagging, filament winding, resin transfer molding, or autoclave curing.
• Proficiency in 3D CAD software (SolidWorks, CATIA, or AutoCAD) for tooling and process design.
• Knowledge of ECO/NPI workflows and documentation requirements.
• Familiarity with ERP and MES systems; experience with Infor Syteline is a plus.
• Basic knowledge of statistical tools (DOE, SPC) and data analytics platforms (Excel, PowerBI, SQL).

Skills & Abilities

• Technical Problem Solving: Ability to identify process issues, analyze data, and implement effective technical solutions.
• Hands-On Approach: Comfortable working on the plant floor to observe, measure, and improve processes.
• Collaboration: Excellent interpersonal skills to work with production operators, engineers, and leadership.
• Attention to Detail: Strong commitment to quality, documentation accuracy, and process control.
• Adaptability: Ability to manage multiple priorities in a fast-paced, high-mix environment.
• Continuous Learner: Keeps current with emerging composite technologies and manufacturing best practices.
