Polymer Chemist / Materials Scientist

Your Next Challenge in Polymer Chemistry

Are you a polymer chemist or materials scientist who enjoys turning new ideas into real-world products? Do you have experience developing polymer formulations and working directly with manufacturing teams to solve problems and improve production?

Purosil is looking for an experienced, hands‑on Polymer Chemist / Materials Scientist to help develop new materials, improve existing products, and support our manufacturing operations.

This is a role for someone who understands both the science behind polymer materials and the practical challenges of manufacturing them. You will work closely with our CTO, engineers, laboratory staff, and production teams to develop formulations, troubleshoot manufacturing issues, improve product quality, and bring new products from the lab to production.

Purosil manufactures polymer composite products, and our work brings together polymer chemistry, materials science, rubber technology, and technical fabrics.

The ideal candidate has experience in polymer formulation development and at least five years of polymer manufacturing experience. Knowledge of silicone and/or organic rubber compounds is especially valuable.

If you enjoy solving technical problems, supporting manufacturing teams, and seeing the results of your work in finished products, we would like to hear from you.

What You'll Do

• Develop new polymer formulations and compounds for new and existing products.
• Work with technical leadership to research new materials and product opportunities.
• Improve material properties, product performance, and manufacturing consistency.
• Test new formulations and determine whether they meet product and customer requirements.
• Help move new materials from laboratory development into full-scale production.
• Work directly with manufacturing teams and production operators to solve material and processing problems.
• Troubleshoot formulation issues, inconsistent material properties, and production quality concerns.
• Identify the causes of manufacturing problems and recommend practical solutions.
• Work with Engineering to improve production processes, processing methods, and product consistency.
• Help establish and maintain production formulations, processing guidelines, and material controls.
• Support manufacturing teams when introducing new formulations or making changes to existing materials.
• Identify opportunities to improve efficiency, reduce material waste, and improve product quality.

Testing, Quality, and Materials Specifications

• Develop testing methods to evaluate raw materials, compounds, and finished products.
• Analyze test results to confirm material performance and product quality.
• Create and maintain material specifications and quality requirements.
• Investigate product performance issues and recommend corrective actions.
• Compare materials and products with customer requirements and competing products.
• Maintain accurate records of formulations, test results, and material performance.
• Work closely with scientists, engineers, manufacturing personnel, suppliers, and customers.
• Explain material requirements and processing recommendations to production teams.
• Prepare technical reports and summarize research, testing, and manufacturing results.
• Coordinate supplier qualification and formulation testing with our sister company in India.
• Coordinate annual round-robin testing with suppliers and sister-company laboratories.
• Attend intercompany “Chemists Only” meetings every six weeks and prepare the Annual Research Report.
• Maintain material databases, formulation records, testing procedures, and technical documentation.
• Ensure materials and products meet applicable specifications and regulatory requirements.
• Stay current with developments in polymer chemistry, materials science, and manufacturing technology.
• Perform other duties as required.

What You Bring

• A master's degree or higher in Chemistry, Materials Science, Chemical Engineering, Polymer Science, or a related field.
• At least 5 years of polymer formulation development experience.
• At least 5 years of polymer manufacturing experience.
• Experience working directly with manufacturing teams to resolve production and material issues.
• An understanding of how polymer formulations behave during processing and manufacturing.
• Experience improving material performance, product quality, and manufacturing processes.
• Strong analytical skills and the ability to interpret technical data.
• Excellent technical writing and reporting skills.
• The ability to manage projects, solve problems, and work independently.

Experience
