Job summary

Keter in the United States is seeking a Process Engineer to establish and sustain robust molding processes for safe, repeatable, and cost-effective production. You will own process definition, control, troubleshooting, and continuous improvement across injection molding operations.

You will collaborate with Operations, Maintenance, Tool Room, and Quality to eliminate variability, scrap, and downtime while implementing SPC, DOE, and Cp/Cpk measures.

Qualifications

• Bachelor’s degree in Engineering (Plastics, Mechanical, Manufacturing, or related).
• 7-10 years of hands-on injection molding process engineering experience.
• Strong understanding of PP and PC material behavior in molding applications.
• Proven ability to analyze data and solve complex process problems.
• Familiarity with Lean Manufacturing and continuous improvement methodologies.
• Proficiency in interpreting drawings, specifications, and process data.

Responsibilities

• Establish scientifically validated process windows for PP, PC, and similar resins.
• Define and maintain golden settings based on melt temperature and shear, injection velocity profiles, pack/hold pressure and time, cooling efficiency and mold temperature control.
• Apply viscosity, shrinkage, and crystallization behavior (PP) and thermal sensitivity (PC) to process design.
• Own process setup sheets, standard work, and controlled parameter limits.
• Train and mentor the organization to run and protect molding processes.
• Lead engineering analysis of defects such as flow hesitation, jetting, sinks, warp, blush, splay, burns, voids, and dimensional instability.
• Correlate defects to material condition, mold design, and machine dynamics.
• Use DOE, cavity pressure trends, and SPC data to drive permanent solutions.
• Partner with Tool Room and Maintenance to optimize cooling circuit performance.
• Support mold trials, steel-safe changes, and new tool introductions.
• Ensure molds are capable of running defined process windows.
• Provide engineering input on wear components and mold PM requirements.
• Own molding-related process capability (Cp/Cpk).
• Implement SPC on critical process parameters and part characteristics.
• Transition quality control from inspection-based to process-controlled.
• Support investigations into scrap, quality holds, and customer complaints with data-driven analysis.
• Support commissioning and validation of equipment and automation.
• Verify machine capability relative to material and mold requirements.
• Optimize cycle time without compromising part performance or mold life.
• Ensure compliance with safety, environmental, and quality policies and procedures.
• Support shift coordination and effective communication to maintain process consistency.
• Other tasks as assigned.

Job description

Summary The Process Engineer is responsible for establishing, stabilizing, and sustaining robust molding processes that deliver safe, repeatable, and cost-effective production. This role owns process definition, control, troubleshooting, and continuous improvement across injection molding operations. The Process Engineer ensures molding processes are documented, controlled, trained, enforced, and partners closely with Operations, Maintenance, Tool Room, and Quality to eliminate variability, scrap, and downtime.

• Lead engineering analysis of complex defects, including flow hesitation, jetting, sinks, warp, blush, splay, burns, voids, and dimensional instability.
• Correlate defects to material condition (moisture, degradation), mold design (venting, cooling, gating), and machine dynamics (pressure response, screw recovery).
• Use DOE, cavity pressure trends, and SPC data to drive permanent solutions
• Partner with Tool Room and Maintenance to optimize cooling circuit performance, venting and gas evacuation, ejection and part release.
• Support mold trials, steel-safe changes, and new tool introductions.
• Ensure molds are technically capable of running defined process windows.
• Provide engineering input on wear components and mold PM requirements.
