* Correlate polymer chemistry with durability, weathering resistance, and long-term stability.
* Establish lab-scale extrusion and film casting protocols for transparent and optical-grade films.
* Define critical process–performance relationships, including haze, tensile strength, elongation, tear resistance, and environmental durability.
* Optimize formulation and processing parameters for high clarity, low birefringence, and minimal defects.
* Build and maintain a competitive intelligence database of global TPU chemistries, extrusion processes, and film performance benchmarks.
* Conduct accelerated aging, optical, and mechanical testing to validate long-term performance targets.
* Translate lab-scale polymer synthesis and extrusion processes to pilot and full production scale.
* Collaborate with process engineers, manufacturing teams, and external partners to ensure successful technology hand-off.
* Identify and protect intellectual property opportunities in TPU/EPU chemistries, extrusion processes, and film applications.
* Stay at the forefront of polyurethane and optical polymer science to drive continuous innovation.
* Provide robust technical solutions to new product development initiatives and lend support to sales and product management teams
* Bridge the gap from bench scale testing to industrial manufacturing processes by taking a lead role in the scale up process
* Develop plans and procedures for specifications & fabrication of components, integration of technologies, balancing cost & manufacturability
* Serve as technical interface to vendors and manufacturers
* Continue to improve upon existing process and product through research and development in the specific area of responsibility
* Remain versed and up to date on polymer chemistry, extrusion and other emerging technologies in the film industry
* Develop and execute testing methodology necessary to ensure products meet industry standards
