Polymer Developer information

What is a Polymer Developer?

A Polymer Developer is a software engineer who specializes in building web applications using the Polymer library, an open-source JavaScript library developed by Google. Polymer allows developers to create reusable custom elements and leverage web components to build fast, modular, and scalable web applications. Polymer Developers often work on front-end development, focusing on creating user interfaces that are both responsive and maintainable. They typically need strong skills in JavaScript, HTML, CSS, and an understanding of modern web standards.

What are the key skills and qualifications needed to thrive as a Polymer Developer, and why are they important?

To thrive as a Polymer Developer, you need a solid background in materials science, chemistry, and polymer engineering, often supported by a relevant degree. Familiarity with laboratory analysis tools (like DSC, FTIR, and GPC), polymer processing equipment, and knowledge of industry standards or certifications is typically required. Strong problem-solving abilities, attention to detail, and effective teamwork distinguish top performers in this field. These skills are vital to ensure the development of innovative, high-quality polymer materials that meet performance and safety requirements.

What are some common challenges Polymer Developers face when integrating web components into large-scale applications?

Polymer Developers often encounter challenges with compatibility and interoperability when integrating web components into large-scale applications, especially if the project involves legacy code or third-party frameworks. Ensuring consistent styling and behavior across different browsers can require additional polyfills and testing. Collaboration with front-end and back-end teams is crucial to establish clear component APIs and maintain code modularity. Successful developers proactively address these issues through thorough documentation, robust testing, and regular communication with cross-functional teams.

What is the difference between Polymer Developer vs Front-End Developer?

AspectPolymer DeveloperFront-End Developer
Required SkillsProficiency in Polymer, JavaScript, HTML, CSS, Web ComponentsProficiency in HTML, CSS, JavaScript, frameworks like React, Angular, Vue
Work EnvironmentDeveloping custom web components using Polymer for modern web appsBuilding user interfaces across various frameworks and technologies
Industry UsageUsed in companies adopting Polymer for web component developmentCommon across industries for general front-end development

Polymer Developers specialize in creating web components using the Polymer library, focusing on custom, reusable UI elements. Front-End Developers have a broader role, working with multiple frameworks and technologies to build complete user interfaces. While both roles require HTML, CSS, and JavaScript skills, Polymer Developers focus on Polymer-specific skills, whereas Front-End Developers have a wider tech stack and project scope.

Summary

This position can be based at our Wilmington, OH or Fontana, CA plant

The Senior Research Engineer / Scientist - Polymer Materials will support the development, optimization, and deployment of PVC material technologies for highperformance, durable building products. This role requires deep fundamentals in polymer science and polymer engineering, with emphasis on PVC chemistry, physics, processing, and structure-property-process relationships, bridging laboratory research and manufacturing implementation.

What You'll Do:

Key Responsibilities

Polymer Formulation & Materials Development

Develop, optimize, and evaluate PVC formulations, including base resins, stabilizer systems, lubricants, impact modifiers, process aids, fillers, and pigments. Apply fundamental polymer science and engineering principles (polymer thermodynamics, viscoelasticity, molecular weight effects, phase behavior, and degradation mechanisms) to guide formulation design. Demonstrate strong understanding of PVCspecific behavior, including fusion/gelation, thermal stability, shear sensitivity, rheology, and morphology development. Establish and interpret structure-property-processing relationships to balance durability, mechanical performance, surface quality, and manufacturability. Conduct laboratoryscale compounding, extrusion, and molding to support new product, cost, and sustainability initiatives. Drive AI assisted material characterizations and formulation development. 

Process & Manufacturing Support

Support PVC extrusion and compounding processes, including formulationdriven troubleshooting of surface defects, instability, degradation, dimensional control, and throughput limitations. Apply polymer processing fundamentals (heat transfer, shear and elongational flow, residence time, die swell, cooling, and orientation effects) to diagnose and resolve manufacturing issues. Partner with manufacturing, quality, and process engineering teams to scale laboratory formulations to robust, highyield production. Support pilotscale and plant trials. 

Testing & Characterization

Design and execute experimental plans using thermal, mechanical, rheological, and environmental characterization techniques (DSC, TGA, DMA, rheometry, weathering, impact, tensile, flexural). Interpret data using firstprinciples understanding of polymer behavior and PVC material response. Maintain high standards for documentation and technical rigor. 

Project Management & Technical Communication

Plan and execute technical projects with defined scope and milestones. Communicate complex polymer concepts clearly through written reports and presentations. Collaborate with suppliers and internal stakeholders. 

What You'll Bring:

Required Qualifications 

PhD in Polymer Science, Polymer Engineering, Materials Science, or Chemical Engineering with 0-7 years of experience, or MS with 3-10 years of experience.  

Strong fundamental knowledge of polymer chemistry and polymer engineering. Deep understanding of PVC materials including stabilization chemistry, fusion behavior, degradation mechanisms, and extrusion processing.  

Experience in AI assisted material characterizations and formulation development for composite materials. 

Strong written and verbal communication skills. 

Travel -35% (mainly domestic) 

Preferred Qualifications 

Handson experience with PVC compounding, extrusion, or formulation development. Experience supporting highvolume manufacturing or pilotscale operations. Familiarity with building materials and durability requirements.
