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.
