Materials Processing:

• 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.

Materials Development:

• 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.

Qualifications:

• 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.
• Hands-on experience working directly with polymeric and additive materials, prototypes, and lab-scale equipment.
• 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.
• Experience in commercialization of products (or product sub-components) through stage-gate processes in regulated industries (e.g., life sciences, automotive, health care,…
