Supplier Quality Engineer (Injection Molding & Tooling) - On site at Cricut

We are seeking a Supplier Quality Engineer (SQE) with strong expertise in plastic injection tooling & molding processes. The ideal candidate will have hands-on experience in defining, optimizing, and validating molding parameters, reviewing and approving tooling designs, selecting appropriate resin materials, and diagnosing process-related defects. This role will work closely with suppliers to ensure robust, stable, and capable manufacturing processes from tool design through mass production. Key Responsibilities - Responsible for supplier quality plastic injection molded components from development through mass production - Review, evaluate, and approve tooling design (mold design) together with Engineering team to ensure manufacturability, quality, and process robustness - Collaborate with Engineering & suppliers on mold flow analysis, gate location, cooling layout, venting, and shrinkage considerations - Evaluate and approve supplier injection molding processes, including parameter setup and process controls - Determine and validate optimal molding parameters - Lead root cause analysis and corrective actions for molding defects (e.g., sink marks, warpage, short shots, flash, burn marks, cracks, breakage) - Assess and ensure correct resin material selection based on product requirements and application - Conduct supplier audits focusing on molding process capability, tooling condition, and quality systems - Drive continuous improvement initiatives with suppliers to enhance yield, reduce variation, and improve process stability - Responsible for review and approve PPAP, FMEA, Control Plans, and SPC data from suppliers. Technical Requirements - Strong knowledge of plastic injection molding processes and tooling design principles - Experience in tool design review , including:   • Gate type and location selection   • Runner system (hot runner / cold runner)   • Cooling channel design and effectiveness   • Venting and air traps   • Ejection system design   • Shrinkage and warpage considerations - Deep understanding of critical process parameters:   • Melt temperature, mold temperature   • Injection speed and pressure   • Holding/packing pressure and time   • Cooling time and cycle optimization etc - Ability to determine process windows and understand parameter variation impact - Experience diagnosing molding defects and linking them to root causes - Knowledge of resin materials (ABS, PC, PP, Nylon, etc.) - Familiarity with scientific molding, decoupled molding, and/or DOE
