Execute physical, mechanical, thermal, and rheological testing on raw, compounded, and recycled plastic resins.

Interpret analytical test data to release production batches, generate Certificates of Analysis (COAs), and quarantine out-of-spec materials.

Maintain, calibrate, and troubleshoot analytical equipment, including Melt Flow Indexers (MFI), Differential Scanning Calorimeters (DSC), FTIR spectrometers, and Universal Testing Machines (UTM).

Lead root-cause investigations for quality non-conformances, customer returns, and processing defects alongside production teams.

Author, update, and validate Standard Operating Procedures (SOPs) in compliance with ISO 9001 and ISO/IEC 17025 standards.

Assist R&D and application teams with new resin formulation trials, compounding optimization, and competitive benchmarking.

Monitor Statistical Process Control (SPC) trends to identify degradation in resin quality before defects occur.

Enforce chemical safety, hazardous waste disposal, and PPE compliance across the laboratory facility.
