+ Develop and create sample parts and tools to support process development and validation.

+ Identify required tools, manage tool procurement, and ensure tools are ordered and received on time.

+ Complete molding production runs and perform thorough validation of each run.

+ Lead early equipment management activities, including workstation design, material presentation, standard work, and single-piece flow.

+ Collaborate with product development teams to ensure design and process capability are fully validated before product launch.

+ Develop test fixtures and prototype tooling to support manufacturing line development and process improvement.

+ Define and control production processes, including tooling and equipment selection, setup, and optimization.

+ Validate design specifications and confirm effective shop floor application of new products, tools, and equipment.

+ Drive the identification and implementation of affordable error-proofing and automation technologies for molding operations.

+ Work closely with operations teams to ensure facilities, equipment, and processes are ready for new product launches.

+ Support the development, implementation, and use of production and control-related processes and documentation, including APQP, Control Plans, Qualification Plans, Engineering Change, Deviations, Corrective and Preventative Actions, DFMEA, PFMEA, PPAP, FAI, DFMA, and SPC tools.

+ Identify, evaluate, and establish new processes and technologies needed to achieve best-cost and quality targets.

+ Manage multiple concurrent projects and deliverables in a fast-paced environment while maintaining high standards of quality and documentation.

+ Communicate effectively with internal teams, customers, and suppliers to align on requirements, resolve issues, and support continuous improvement.
