POSITION TITLE   

Lab Technician – Plastics Additives R&D   

 

POSITION OVERVIEW   

We are hiring a Lab Technician to execute analytical testing, support polymer processing trials, manage sample workflows, and coordinate across R&D, analytical labs, Technical Service & Development, regulatory, shipping, and commercial teams—a high-visibility role where your data directly informs product-release decisions, customer readiness, and commercialization timelines. 

 

JOB RESPONSIBILITIES   

  • Execute analytical testing across polymer characterization and additive-analysis methods, including FTIR, GC, active oxygen, moisture, MFR, DSC, Crystex, SAOS/rheology, gel content, impact, and flexural testing. 

  • Support polymer processing trials, including twin-screw extrusion compounding, injection molding, and blending operations—from material staging and parameter setup through sample collection, evaluation, and troubleshooting. 

  • Manage sample workflows end-to-end—preparation, labeling, safe handling and storage of additives including peroxides and oxidizers, inventory tracking, QC release, and domestic/international shipment with SDS and regulatory documentation. 

  • Coordinate across functions as the operational link between R&D scientists, analytical specialists, TS&D engineers, sales, regulatory, shipping, tolling facilities, and customer technical contacts. 

  • Maintain data integrity across shared project datasets, master data files, QC spreadsheets, laboratory records, and Technical Service Requests (TSRs). 

  • Support method development, validation, and transfer, including documentation, calibration standards, and troubleshooting analytical variability. 

  • Communicate proactively—provide updates, flag risks, close loops, and keep stakeholders informed across concurrent projects. 

 

QUALIFICATIONS - REQUIRED   

  • B.S. in Chemistry, Polymer Science, Materials Science, Chemical Engineering, or related discipline 

  • 2+ years of hands-on laboratory experience in a polymer, plastics, or chemical environment 

  • Proficiency in multiple polymer characterization or analytical chemistry techniques 

  • Working knowledge of sample preparation, handling, and storage for polymer and chemical-additive materials 

  • Proficiency with Microsoft Office (Excel, Word, Outlook, Teams) and a LIMS or lab notebook 

  • Strong organizational, communication, and multi-tasking skills 

 

QUALIFICATIONS - PREFERRED 

  • M.S. in a related field; 3+ years in plastics additives or polyolefin environments 

  • Hands-on experience with polymer processing equipment, including twin-screw extruders, injection molding machines, single-screw extruders, or dry-blending/compounding equipment 

  • Experience with advanced characterization techniques (Crystex, TREF/TGIC, GPC, SAOS, SEM) 

  • Familiarity with method development/validation, DOE, JMP or Minitab, SAP, and international shipping documentation 

 

The successful candidate will have strengths in the following:   

Analytical Rigor 

Produce data people can bet decisions on—accurately and independently 

Problem Solving 

Investigate anomalies and propose next steps, not just report results 

Processing Aptitude 

Understand how materials behave during extrusion, molding, and compounding—and how processing affects performance 

Ownership 

Track work from request to completion; nothing falls through the cracks 

Cross-Functional Fluency 

Speak the language of the lab, the plant, the customer, and the shipping dock
