Our Team
You'll join our Manufacturing Engineering team, owning the full injection molding lifecycle — from mold qualification through steady-state production — to ensure our processes and tooling consistently deliver quality parts on time. This role involves optimizing production efficiency, ensuring product quality, and driving continuous improvement initiatives in molding operations
What You Will Do
- Develop, optimize, and validate injection molding processes for new and existing products, balancing cycle time, quality, and cost
- Evaluate mold designs for manufacturability and partner with mold makers on tool builds, modifications, and repairs
- Troubleshoot process- and tooling-related defects on the production floor, driving root cause analysis and corrective actions
- Lead mold sampling, first-article inspection, and process/tool qualification for new and revised programs
- Run DOEs to establish robust process windows and reduce variation across shifts and machines
- Plan and oversee preventive maintenance schedules to maximize tool life and minimize unplanned downtime
- Collaborate with product design, quality, and production teams during new product introduction (NPI)
- Maintain process and tooling documentation, including work instructions, control plans, and mold records
Who You Are (Basic Qualifications)
- Bachelor's degree in Mechanical, Plastics, Manufacturing Engineering, or related field
- 3+ years of experience in injection molding process engineering, tooling engineering, or a combined role
- Working knowledge of thermoplastic materials and mold construction (cold runner, hot runner, multi-cavity)
- Experience with process validation (IQ/OQ/PQ) and mold qualification activities
- Proficiency with CAD software for mold/part review (e.g., SolidWorks, Moldflow, or similar)
What Will Put You Ahead
- Proficiency with Siemens NX software
- Hands-on machining or mold-building experience (CNC, EDM, grinding)
- Familiarity with mold flow simulation and scientific molding principles
- Experience with plastic injection molding, hot runner systems and advanced gating techniques
- Background in automotive, medical device, or consumer electronics manufacturing
- Six Sigma or lean manufacturing certification
