What does a polymer engineer do?

A Polymer Engineer specializes in the design, development, and testing of polymer materials, which include plastics, rubbers, and composites. They work on improving the properties of these materials to meet specific performance requirements for various industries such as automotive, aerospace, medical, and consumer goods. Their responsibilities often include research, product development, quality control, and troubleshooting manufacturing processes. Polymer Engineers also collaborate with chemists, material scientists, and engineers from other disciplines to create innovative products and solutions.

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 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 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 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

Amazon Leo is Amazon's low Earth orbit satellite network. Our mission is to deliver fast, reliable internet connectivity to customers beyond the reach of existing networks. From individual households to schools, hospitals, businesses, and government agencies, Amazon Leo will serve people and organizations operating in locations without reliable connectivity.
We are seeking a Sr

Aerospace Hardware Development Engineer to join the Solar Design Team. In this role, you will lead the design, development, and qualification of solar array hardware for next-generation LEO constellation spacecraft. You will own solar array hardware development across the array portfolio, which includes solar power modules, deployable wing structures, secondary structures, and array-level mechanical interfaces.

You will be expected to operate broadly across this hardware and step into ownership of critical subsystems as the team scales.
The ideal candidate is a strong mechanical or aerospace engineer with experience in solar array hardware, deployable structures, or lightweight aerospace assemblies. Experience with composites, adhesive bonding, thin-film polymers, or flexible substrate technologies is highly valued, as the team is actively developing next-generation lightweight array concepts. You are comfortable taking ambiguous hardware problems from requirements definition through qualification, and you maintain a hands-on connection to your hardware throughout the development cycle.
Export Control Requirement: Due to applicable export control laws and regulations, candidates must be a U.S

citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.
Key job responsibilities
Lead the design, analysis, and qualification of solar array subsystems (modules, wing structures, composites, secondary structures, mechanical interfaces) from concept through production readiness.
Drive materials selection, and qualification for lightweight array structures, including adhesive bonding, composites, polymer films, and thin-film encapsulants.
Create and iterate detailed CAD and engineering artifacts including geometry, schematics, ply schedules, material selections, and test methods.
Develop validation and qualification campaigns including environmental testing, materials characterization, and hardware acceptance suitable for mass production.
Perform or direct structural, thermal, and durability analysis to verify design margins and support trade studies.
Lead technical engagements with materials suppliers, cell vendors, and manufacturing partners.
Collaborate with adjacent teams (power systems, structures, thermal, mechanisms, manufacturing) on interfaces and integration.
Lead and participate in design reviews

Present hardware status and trade-offs to technical leadership.
A day in the life
You will operate with significant autonomy, owning the development of array hardware subsystems end-to-end. Your time will split between design and analysis, collaboration with cross-functional partners, and hands-on work in the lab with your hardware. The ideal candidate is self-motivated and comfortable making engineering decisions in a fast-paced environment where priorities and focus areas evolve with program needs.
About the team
The Solar Design team owns the design, qualification, and technology development of the satellite solar array assembly, including solar power modules, secondary structures (wings, frames, blankets), and array-level interfaces and deployment mechanisms

The team supports multiple concurrent programs from production support through next-generation development and advanced R&D. You will work within the Mechanical Engineering organization and collaborate broadly with Power Systems, Structures, Thermal, Mechanisms, Manufacturing, and Mission Operations teams.
