About this role

Principal R&D Engineer - TPU Chemistry and Processing San Antonio, TX Job Summary: The Principal Research and Development Engineer will lead and oversee their respective area(s) of development of XPEL's core technology. Core Duties Lead fundamental research into TPU/EPU polymer architecture (soft/hard segment ratios, chain extenders, isocyanates) and their effects on optical, thermal, and mechanical performance. 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
