• Perform failure investigations using structured problem-solving techniques and statistical methods to identify root causes and implement effective corrective and preventive actions.
• Author test protocols and execute validation protocols, including IQ, OQ, and PQ activities, to meet ISO and FDA medical device regulatory requirements.
• Verify that all required documents and records are correctly completed and approved prior to process setup and sign-off.
• Provide training, coaching, and technical guidance to peers and Process Technicians on scientific molding, process control, documentation, and best practices.
• Maintain and promote a safe and clean working environment by following established housekeeping, organization, and safety practices.
• Follow all applicable safety procedures and guidelines as outlined in the company safety manual and reinforce safe behaviors on the production floor.
• Support on-the-floor documentation activities, ensuring that process changes, validations, and production records are properly recorded and controlled.
• Contribute to the implementation and support of Lean Manufacturing tools, such as 5S and value stream mapping, to improve workflow and reduce waste.
• Perform other related duties as necessary to support production, quality, and engineering objectives.

Essential Skills

• Hands-on experience in plastic injection molding, including developing and optimizing molding processes.
• At least 1 year of experience implementing decoupled molding processes and applying scientific molding techniques.
• Proficiency with scientific molding methods such as gate freeze analysis, short shot analysis, and related analytical techniques.
