Polymer Research Engineer information

What does a polymer research engineer do?

A Polymer Research Engineer specializes in the study, development, and testing of new and existing polymer materials. They work to improve the properties of plastics, rubbers, and other polymers for various applications, such as packaging, automotive parts, or medical devices. Their responsibilities often include conducting experiments, analyzing data, and collaborating with other scientists and engineers to innovate or enhance polymer products. Additionally, they may be involved in scaling up laboratory findings to industrial production processes.

What are the key skills and qualifications needed to thrive as a polymer research engineer?

To thrive as a Polymer Research Engineer, you need a solid background in polymer science, materials engineering, and analytical chemistry, typically supported by a relevant bachelor's or advanced degree. Familiarity with laboratory instrumentation, polymer characterization techniques (such as DSC, FTIR, and GPC), and experience with software for data analysis are commonly required. Strong problem-solving, collaboration, and communication skills help you effectively design experiments and present findings. These competencies are crucial for developing innovative polymer materials and driving advancements in materials science.

What are the most common challenges a polymer research engineer faces when developing new polymer materials?

Polymer Research Engineers often encounter challenges such as balancing material performance with cost-effectiveness, ensuring scalability from laboratory to industrial production, and meeting strict regulatory and safety standards. Additionally, they must stay updated with advances in polymer chemistry and processing technologies while collaborating closely with cross-functional teams like manufacturing, quality assurance, and product development. These challenges require strong problem-solving skills, adaptability, and effective communication to drive innovation and achieve project goals.

Job description

Syensqo is all about chemistry. We're not just referring to chemical reactions here, but also to the magic that occurs when the brightest minds get to work together. This is where our true strength lies. In you. In your future colleagues and in all your differences. And of course, in your ideas to improve lives while preserving our planet's beauty for the generations to come.
We are looking for:
The Polymer Sr. Additives Application Scientist (Polyolefin Stabilization & Formulations) will provide technical application leadership to develop, validate, and support polymer additive solutions for polyolefins, with deep expertise in functional additives and formulation development. Also the purpose of the role is to generate high-quality application data, translate customer needs into robust formulations, and support commercial growth across key segments including automotive, agriculture, building & construction, wire & cable, durable goods, and molding applications.
We count on you for:
Application & Formulation Development
  • Design and optimize polyolefin stabilization packages (UV stabilizers, UV absorbers and antioxidants) for PP/PE and related resin systems.
  • Able to formulate with complementary additives (e.g., pigments, flame retardants, slip/antiblock agents, fillers) to meet performance and regulatory requirements for targeted applications.
  • Build "Cause and Effect" understanding linking additive chemistry, processing history, and end-use performance.

Polymer Processing & Sample Preparation
  • Plan and execute polymer processing trials using extrusion (single/twin-screw), injection molding, compression molding, and related compounding/conversion methods.
  • Define processing windows and assess effects of shear/temperature/oxygen exposure on stabilization performance (melt stability, color, odor, die build-up, etc.).

Testing, Characterization & Data Generation
  • Lead accelerated weathering and durability evaluations (e.g., UV exposure, thermal aging), including test plan definition, controls, and interpretation.
  • Conduct, analyze, and interpret test results. (e.g., MFR/MFI, DSC/OIT, TGA, tensile/impact/flexural, hardness, color/ΔE, gloss, haze, density; as relevant).
  • Develop statistically sound application datasets and technical documentation to support product positioning, claims, and customer trials.

Technical Support & Troubleshooting
  • Provide expert technical support to internal teams and customers: troubleshoot formulation, processing, and performance issues; propose corrective actions and validate solutions.
  • Troubleshoot and maintain key lab/testing instruments; coordinate repairs/calibration with vendors and internal resources as needed.

Cross-Functional Collaboration
  • Partner with R&D, Product Management, Sales, Manufacturing, Quality, Regulatory, and Supply Chain to align on priorities, launch readiness, and customer support.
  • Contribute to innovation pipelines by identifying unmet needs and proposing new additive concepts, test methods, or application platforms.

External Visibility & Knowledge Sharing
  • Prepare and deliver technical presentations at customer meetings and industry conferences; contribute to papers/posters where appropriate.
  • Capture competitive intelligence and market trends; share learnings internally to improve products and messaging.

You can count on us for:
  • We offer the opportunity to join an exciting growth company
  • A full range of benefits as expected of a successful company
  • Opportunities for growth and learning
  • Encouraging a diverse and inclusive workplace culture that values and respects individual differences and backgrounds

You will bring:
  • PhD or MSc in Polymer Science, Chemistry, Chemical Engineering, Materials Science, or related field (or equivalent experience).
  • 10+ years of experience in polymer additives application development, with strong focus on polyolefin stabilization and formulations.
  • Demonstrated expertise in UV stabilizers/HALS, UV absorbers, antioxidants, including interactions and performance trade-offs (process vs. long-term stability).
  • Solid knowledge of polyolefin end-use requirements in automotive, agriculture, building & construction, wire & cable, durable goods, and molding applications.
  • Hands-on experience with polymer processing: extrusion, injection molding, compression molding (compounding/conversion experience strongly preferred).
  • Experience with accelerated weathering and durability testing and interpreting failure modes.
  • Competency in polymer characterization and physical testing; ability to design test plans and draw clear, defensible conclusions.
  • Familiarity with additional additives: pigments, flame retardants, slip/antiblock agents, processing aids, etc.
  • Strong communication skills: clear technical writing, data storytelling, and conference-level presentation capability.

Preferred Qualifications
  • Experience with customer trial support and stage-gate development projects.
  • Knowledge of relevant standards/methods (e.g., ISO/ASTM; weathering standards and durability requirements).
