Performs mechanical, physical, and properties testing on Polyolefin and Specialty Products, including resins, films, and molded parts (e.g., tensile/secant, hot tack, dart, puncture, tear, melt index, density, coefficient of friction (COF), oxygen transmission rate (OTR), water vapor transmission rate (WVTR), heat sealing, Differential Scanning Calorimetry (DSC), and Thermogravimetric Analysis (TGA)). Testing may include solid, liquid, and intermediate materials across polymeric and chemical systems. Prepares and tests samples by reading and strictly following detailed ASTM, ISO, and site-specific standard methods to generate high quality, reliable data. Operates, maintains, and troubleshoots analytical, physical properties, and process development equipment, including large industrial-scale fabrication equipment (e.g., film and molded parts fabrication). Conducts advanced, controlled testing and scientific experiments to support product development, business decisions, and customer requests; may perform work in fume hoods or dry boxes. Provides analytical testing and technical support for multiple ExxonMobil business lines, including polymer, specialty materials, Proxxima™, and selected chemicals applications. Interfaces daily with internal customers, including PhD. scientists and engineers, and engages external customers as requested by business groups. Calculates, analyzes, interprets, and documents test results; uploads data to digital lab management and work order management systems for technical review. Ensures data integrity and compliance through adherence to quality objectives, site requirements, and safety standards; develops and maintains method documentation, SOPs, and supporting materials. Performs methods and analytical development work as needed to support new products, technologies, and evolving business needs. Solves analytical and technical problems and leads or supports efforts to introduce new testing methods, instrumentation, or technologies. Stewards third party instrument calibrations and performs internal calibrations, equipment verifications, gauge testing, and SQC chart monitoring to ensure quality compliance. Efficiently manages work requests, prioritizes tasks, and maintains turnaround times in alignment with business expectations. Operates and maintains sample inventory systems, including sample handling, tracking, storage, shipping, and proper disposal. Demonstrates strong safety awareness and actively uses Exxon safety tools to enhance personnel and process safety safeguards.
