What are some typical challenges polymer engineers face when working on new material development projects?

Polymer Engineers often encounter challenges such as balancing material properties to meet specific application requirements, ensuring compatibility with manufacturing processes, and addressing cost constraints. Collaborating with cross-functional teams—including chemists, product designers, and manufacturing specialists—is essential to troubleshoot issues and innovate solutions. Additionally, staying current with industry regulations and sustainability trends can add complexity, but also opens opportunities for creative problem-solving and professional growth.

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

To thrive as a Polymer Engineer, you need a solid background in polymer science, materials engineering, and chemistry, typically supported by a relevant bachelor's or master's degree. Proficiency in simulation software (such as MATLAB or ANSYS), laboratory instrumentation, and familiarity with industry standards and testing protocols is crucial. Strong problem-solving skills, attention to detail, and effective teamwork and communication abilities set candidates apart in this field. These skills are essential to innovating, ensuring product quality, and successfully collaborating on multidisciplinary projects in the development of new polymer materials and applications.

What does a polymer engineer do?

A polymer engineer primarily works in plastics development. In this career, you develop and test plastics or related materials. Your responsibilities include the fabrication of new polymers, working with the prototype, and designing new equipment to process these materials. You also provide support for all plastic injection molding techniques and monitor customer issues, working to resolve them quickly. You analyze and evaluate the success of each new plastic or polymer. You also research and analyze ongoing developments in the plastics field and select polymers for new applications and testing. Other duties include maintaining product improvement policies and promoting efficient lab operations.

What is the difference between Polymer Engineer vs Materials Scientist?

AspectPolymer EngineerMaterials Scientist
Required CredentialsBachelor's or Master's in Polymer Science, Chemical Engineering, or Materials ScienceBachelor's or Master's in Materials Science, Chemistry, or Physics
Work EnvironmentResearch labs, manufacturing facilities, R&D departmentsResearch labs, academia, industry R&D
Industry UsagePlastic, rubber, polymer product manufacturingBroad industry applications including metals, ceramics, polymers

Polymer Engineers focus specifically on the development and manufacturing of polymer materials, while Materials Scientists have a broader scope, studying various materials including metals, ceramics, and polymers. Both roles often collaborate and share similar educational backgrounds, but Polymer Engineers are more specialized in polymer applications and production processes.

Job description

Company / Location Information

A.O. Smith is a global leader applying innovative technologies and energy-efficient solutions to products manufactured and marketed worldwide. The company is one of the world's leading manufacturers of residential and commercial water heating equipment and boilers, as well as a manufacturer of water treatment products for residential and light commercial applications. A. O. Smith is headquartered in Milwaukee, Wisconsin, with approximately 12,000 employees at operations in the United States, Canada, China, India, Mexico, the Netherlands, and the United Kingdom. 

Primary Function

The Materials Engineer - Polymers will be a part of our Lloyd R. Smith Corporate Technology Center (CTC) Team in Milwaukee, WI. The CTC contains a multidisciplinary team of engineers and technicians with the purpose of researching, developing, and supporting technologies on a 3-5 year time horizon. This role will serve as the organization's Subject Matter Expert for plastics, rubbers, elastomers, and other polymeric materials used in water heating and water treatment equipment. The engineer will support global business units, manufacturing plants, quality teams, sourcing, suppliers, and product engineering by providing technical guidance on material selection, qualification, failure analysis, root cause investigation, product performance issues, and application suitability. The role will also develop analytical approaches and test methods to assess material performance and will conduct forward-looking research into new materials, additives, compounds, processing methods, and manufacturing technologies.

Responsibilities
  • Serve as the organization's Subject Matter Expert for polymeric materials, including plastics and rubbers, and educate the organization on material behavior, degradation mechanisms, chemical compatibility, processing effects, supplier variation, emerging material technologies, and best practices for material selection and use.
  • Lead materials-related failure analysis and root cause investigations for plastics, rubbers, elastomers, seals, gaskets, molded components, and other polymeric materials, including development of structured investigation plans, use of appropriate characterization methods, interpretation of evidence, documentation of findings, and recommendations for corrective actions.
  • Provide technical support to business units, manufacturing plants, quality teams, sourcing, suppliers, and product engineering teams on polymer-related product complaints, performance issues, material substitutions, and application suitability questions; develop analytical approaches and test methods needed to assess material performance and application suitability.
  • Support business unit needs by making recommendations for selecting, evaluating, and qualifying polymeric materials, including thermoplastics, thermosets, rubbers, elastomers, and composite materials, for water-contact, high-temperature, pressure-bearing, sealing, and chemically exposed applications.
  • Conduct forward-looking research into new polymeric materials, additives, compounds, processing methods, manufacturing technologies, and supplier capabilities that could improve product performance, reliability, cost, sustainability, manufacturability, or competitive differentiation.
  • Work with internal and external testing labs to verify material and product performance, develop new test methods as needed, and translate test data into well-communicated, practical recommendations for design, quality, manufacturing, and supplier decisions.
Qualifications
  • Master's or PhD in Polymer Engineering, Materials Science, Chemical Engineering, Mechanical Engineering, or related field.
  • 7 years of relevant experience. Candidates with less experience may be considered based on depth of expertise.
  • Demonstrated expertise in polymer engineering, materials failure analysis, root cause investigation, and technical problem solving; experience with adjacent materials such as metals, enamels, foams, adhesives, or coatings is beneficial.
  • Significant experience with plastics, rubbers, elastomers, and polymer characterization methods, including mechanical testing, thermal analysis such as DSC, TGA, and DMA, rheology and melt flow evaluation, spectroscopy such as FTIR, microscopy including SEM/EDS, hardness testing, compression set, chemical compatibility and swelling evaluation, aging studies, and other methods used to assess polymer composition, degradation, processing effects, and application performance.
  • Experience evaluating polymer degradation, environmental stress cracking, chemical attack, swelling, embrittlement, creep, fatigue, wear, aging, compression set, sealing performance, and other application-specific failure modes.
