What are some typical challenges a junior polymer engineer might face when working on new material development projects?

As a Junior Polymer Engineer, you may encounter challenges such as understanding the complexities of polymer behavior under different processing conditions and adapting to rapidly evolving material requirements. Collaborating with cross-functional teams—including chemists, product designers, and manufacturing staff—can also present communication and technical alignment hurdles. Additionally, balancing hands-on laboratory work with data analysis and documentation responsibilities often requires strong organizational skills and adaptability. With mentorship and experience, these challenges become valuable learning opportunities that contribute to your professional growth.

What does a junior polymer engineer do?

A Junior Polymer Engineer assists in the research, development, testing, and production of polymer materials, such as plastics, resins, and composites. They typically support senior engineers by conducting experiments, analyzing materials, and troubleshooting issues in manufacturing processes. Their responsibilities may also include collecting and interpreting data, preparing reports, and ensuring that materials meet quality and safety standards. This entry-level role is designed to build foundational skills in polymer engineering and provide hands-on experience in the field.

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

To thrive as a Junior Polymer Engineer, you need a solid background in polymer science, materials engineering, or chemical engineering, typically supported by a relevant bachelor's degree. Familiarity with laboratory equipment, polymer characterization techniques, and software such as MATLAB or CAD tools is frequently required. Strong problem-solving abilities, teamwork, and effective communication skills help you excel in research and development environments. These competencies ensure precise analysis, successful collaboration, and innovative solutions in the rapidly evolving polymer industry.

What is the difference between Junior Polymer Engineer vs Polymer Technician?

AspectJunior Polymer EngineerPolymer Technician
Required CredentialsBachelor's degree in Polymer Science, Chemical Engineering, or related fieldAssociate degree or technical certification in polymer technology
Work EnvironmentDesign, research, and development labs; collaborative engineering teamsManufacturing plants; quality control labs; hands-on production settings
Employer & Industry UsageResearch institutions, chemical companies, R&D departmentsManufacturers, production facilities, quality assurance teams

Junior Polymer Engineers typically focus on research, design, and development of polymer products, requiring a degree and analytical skills. Polymer Technicians usually work in production and quality control, with technical certifications. Both roles are essential in the polymer industry but differ in responsibilities and work settings.

Job description

We are seeking a Medical Device Engineer with developing to advanced expertise in expanded PTFE (ePTFE) materials and device applications. This role supports and/or leads the design, development, and commercialization of ePTFE-based medical devices and components used in implantable and catheter-based systems.
The role spans from independent contributor (Engineer II) through technical project leadership (Senior Engineer), with increasing responsibility for design ownership, cross-functional leadership, and workstream execution.
This position operates in a regulated ISO 13485 environment and partners closely with R&D, Quality, Operations, Regulatory, and external suppliers to deliver safe, effective, and manufacturable medical products.
Key Responsibilities
Product & Process Development
  • Contribute to or lead design and development of ePTFE-based medical devices and components from concept through commercialization
  • Develop, optimize, and scale manufacturing processes for ePTFE constructs (tubes, films, sheets, grafts, and custom geometries)
  • Translate user needs and design inputs into robust, manufacturable design outputs

Testing & Characterization
  • Design and execute material and device-level test methods including:
    • Tensile and mechanical testing
    • Burst pressure and leak testing
    • Suture retention
    • Permeability and porosity characterization
  • Interpret data and drive design or process improvements based on results

Supplier & Material Management
  • Support supplier engagement, development, and qualification activities
  • Define and maintain raw material specifications for ePTFE and related components
  • Partner with suppliers to resolve material variability and process capability issues

Risk & Compliance
  • Participate in design and process risk management activities (e.g., FMEA, material risk assessments)
  • Ensure design controls and documentation comply with ISO 13485 and applicable regulatory requirements
  • Support audit readiness and regulatory submissions as needed

Technical Documentation & Communication
  • Develop and maintain design history file (DHF) documentation, protocols, reports, and technical summaries
  • Communicate technical findings clearly across R&D, Quality, Operations, and external partners
  • Support customer and internal technical discussions as required

Problem Solving & Execution
  • Lead structured problem-solving activities using data-driven methodologies
  • Troubleshoot product and process issues through root cause analysis and corrective actions
  • Drive closure of technical issues with appropriate urgency and rigor

Competency Framework
Core Technical Competencies
  • Deep understanding of ePTFE structure-property relationships and processing behavior
  • Strong foundation in materials science (especially fluoropolymers)
  • Knowledge of mechanical behavior of porous and expanded polymer systems
  • Ability to design experiments (DOE mindset) and interpret statistical/engineering data
  • Familiarity with medical device design controls and ISO 13485 systems

Engineering Execution Competencies
  • Structured problem solving (root cause analysis, hypothesis-driven investigation)
  • Experimental design and validation of design/process changes
  • Data analysis and technical decision-making under uncertainty
  • Ability to balance design intent with manufacturability constraints

Project & Technical Leadership (Senior Level Emphasis)
  • Ability to independently lead technical workstreams or device development activities
  • Coordinates cross-functional inputs and drives alignment on technical decisions
  • Mentors or guides junior engineers and technical contributors
  • Manages priorities across multiple development activities with minimal oversight

Communication & Collaboration
  • Clear and concise technical writing for regulated documentation
  • Effective communication across R&D, Quality, Operations, and suppliers
