Essential Duties and Responsibilities:

• Design and develop CAD models and engineering drawings for plastic components and assemblies using SolidWorks.
• Create and optimize CAM toolpaths for CNC turning and milling of plastic materials using SolidCAM, Cimatron, and/or Alphacam.
• Develop cutting strategies and parameters optimized for plastic substrates (Acrylic, Polycarbonate, HDPE, UHMW-PE, PVC, Delrin, Nylon).
• Design jigs, fixtures, and work-holding solutions for CNC turning, milling, and routing operations on plastic parts.
• Collaborate with production teams to translate design intent into manufacturable processes.
• Perform Design for Manufacturability (DFM) reviews and recommend design modifications to improve producibility.
• Write and maintain Standard Operating Procedures / Work Instructions (SOP/WI) for machining processes.
• Support new product introduction (NPI) by developing programs and process parameters from prototype to mass production.
• Conduct process validation and capability studies for new and existing machining processes.
• Participate in and lead troubleshooting for machining defects; identify root causes and implement corrective actions.
• Ensure periodical achievement of Process Failure Mode Effect Analysis (PFMEA).
• Interface with contractors, suppliers, and stakeholders for tooling and material specifications.
• Identify opportunities for process optimization, cycle time reduction, and continuous improvement.
• Verify quality of machined parts using CMM, surface roughness tester, calipers, and other measuring equipment.
• Perform other related duties as required.

Knowledge, Skills and Abilities:

• Speaks fluent English with good communication abilities; experience communicating projects in a global company.
• Strong proficiency in CAD/CAM systems: SolidWorks, SolidCAM, Cimatron, and Alphacam.• Deep understanding of CNC turning and milling processes for plastic materials.
• Proficient with G & M code (Fanuc & Okuma OSP preferred).
• Able to interpret and create mechanical drawings; strong knowledge of GD&T.
• Knowledge of plastic material properties, thermal behavior, and machining characteristics.
• Strong analytical, problem-solving, and design-thinking skills.
• Experience with Design for Manufacturability (DFM) principles.
• Implementation and monitoring of work routines.
• Proficient with Microsoft Office Suite.
• Plastic manufacturing related experience is an advantage.

Educational and Experience:

• Minimum 3–5 years of experience as a CNC Design Engineer or CNC Programmer in a machining environment.
• Degree in any engineering discipline, preferably Mechanical or Mechatronic.
• Knowledge of manufacturing processes, fabrication methods, and tool & fixture design.
• Experience in machining of plastic materials is highly preferred.
• Familiarity with manufacturing process equipment and quality assurance techniques.
• Experience in CNC programming for Milling, Lathe, and Turn-mill machines (3-axis, 5-axis Milling & 4-axis Turn - mill).
• Well-versed in SolidWorks, SolidCAM, Cimatron, and Alphacam.
• Working in ISO 9001:2015 environment organizations.
