Position Overview:

The Quality & Materials Engineer will lead the development, documentation, and implementation of all material testing and quality control systems for Supersede’s recycled and extruded plastic products. This role will be responsible for creating standardized testing procedures, analyzing data, and ensuring product compliance with internal and external standards.

The ideal candidate will have a strong background in plastics testing, materials characterization, and product design. They will play a critical role in qualifying new formulations, supporting extrusion and compounding operations, and validating finished product performance. This position requires a hands-on, detail-oriented engineer who can independently manage a quality lab environment while collaborating across engineering, production, and product development teams.

This position is based in Phoenix, Arizona, and will require travel (up to 25%) to our Elkhart, Indiana facility for equipment commissioning, testing support, and quality audits.

Key Responsibilities

• Develop, document, and implement testing procedures for various plastics properties in accordance with ASTM and ISO standards.

• Establish and maintain Supersede’s quality laboratory, including equipment calibration, maintenance, and operator training.

• Conduct materials testing and data analysis to support material qualification, product development, process validation, and production.

• Design and execute Design of Experiments (DOE) to evaluate process variables and optimize material properties.

• Design and execute Design of Experiments (DOE) to evaluate end use applications and assemblies.

• Collaborate with R&D, extrusion, and production teams to ensure consistent quality of recycled and compounded materials.

• Lead quality control initiatives across raw materials, in-process production, and finished goods.

• Develop control plans, maintain documentation, sampling procedures, and acceptance criteria for production quality systems to meet all required certification criteria (ISO, ICC, USCG, etc.)

• Support product certification efforts by preparing test reports, data packages, and technical submissions to accrediting bodies.

• Utilize CAD software to assist in product and tooling design, testing fixtures, and custom fixture setups.

• Lead project management of material certifications including defining requirements, coordinating vendors, conducting testing, recording results, and maintaining required records to maintain certifications.

• Continuously improve testing processes, documentation, and data integrity through lean and Six Sigma methodologies.

Qualifications:

• Bachelor’s degree in Mechanical Engineering or Materials Engineering required.

• Minimum 3 years of experience in materials testing, product development, or quality engineering — preferably within plastics extrusion, compounding, or building materials industries.

• Hands-on experience performing physical and mechanical tests (e.g., tensile, flexural, impact, hardness, melt flow).

• Proficiency in Design of Experiments (DOE), statistical analysis, and test data interpretation.

• Experience working with or preparing for accreditation and compliance under ISO, ICC, USCG, or similar standards.

• Strong understanding of polymer materials, mechanical properties, and failure modes.

• Experience designing products and fixtures in CAD software (SolidWorks or AutoCAD preferred).

• Familiarity with quality management systems (QMS), control plans, and process validation.

• Excellent technical writing and documentation skills.

• Ability to work independently, manage multiple projects, and communicate effectively across departments.

• Willingness to travel up to 25% between Phoenix, AZ and Elkhart, IN.
