Responsibilities
Lead resin characterization, resin qualification, and change management activities to ensure continuity of supply and performance
Evaluate and screen new supplier materials for performance, quality, regulatory compliance and cost
Oversee resin grinding, sieving, conveying milling, blending, dust-collection, compounding and preparation steps required for downstream processing
Conduct pilot trials, scale-up trials and full-scale production trials, including data capture, risk assessment, and validation
Develop and optimize polymer processing equipment including sintering, melt extrusion, melt blowing, compression molding, injection molding, and post-processing operations
Establish structure-processing-property relationships to guide formulation and process selection
Troubleshoot processing issues, yield loss, and field performance deviations using structured root cause analysis
Partner with operations to transition materials and processes from lab to manufacturing and to optimize cycle time, throughput, scrap and material utilization
Qualify new tooling, equipment, and suppliers to meet product and manufacturing requirements
Generate technical documents including processing specifications, control plans, validation protocols, and reports
Formulate and evaluate polymer materials for porous media, filtration, separation, or other performance-critical applications
Translate customer needs into material attributes, specifications, and test plans. Conduct lab-scale experimentation including resin selection, additives, surface treatments, and coating strategies
Apply material characterization tools such as laser diffraction, bulk density measurements, DSC, TGA, DMA, FTIR, SEM, rheology and porometry to establish structure–property relationships
Drive material down-selection and qualification based on manufacturability, performance, durability, safety and cost
Engage directly with resin suppliers to understand chemistries, stabilizers, regulatory aspects and long-term supply considerations
Support trial planning, application testing, validation, and documentation needed for commercialization
Contribute to intellectual property where novel materials or processes deliver differentiating value
Qualification
Required
Bachelor's or master's degree in engineering (e.g., chemical, materials science, mechanical, industrial or a closely allied field) is required
5+ years of experience in polymer materials development, polymer processing, and/or product development
Must be highly hands-on and comfortable working directly with polymeric and additive materials, prototypes, and lab-scale equipment throughout the development
Strong experience in polymeric materials related products and test methods, preferably in technologies encompassing filtration, separation, or purification
Proficiency in statistical software/analysis and Microsoft Office Suite is needed
Experience in commercialization of products (or product sub-components) through stage-gate processes in regulated industries (e.g. life sciences, automotive, health care, diagnostics, air care markets)
Strong communication, problem-solving and interpersonal skills
Willingness to travel 10-20% as needed for supplier or customer visits
Preferred
Product development and launch experience in an ISO9001 and/or ISO13485 environment would be a plus
