Sr. Materials Engineer

In this role, you will provide technical guidance for mold-in-color, painted plastics, and finished materials. Partnering closely with Product Development and Color Materials & Finishes (CMF), you will bridge design intent with engineering feasibility guiding materials from early prototyping through validation and production.

Development & Prototyping: Partner with Product Development and CMF to drive material selection, prototyping, and production application for mold-in-color and painted plastics.

Validation & Standards: Author Rivian Materials Standards and Test Specifications, and lead material sign-offs through the Engineering Validation process.

Advanced Materials & Sustainability: Lead materials R&D focused on sustainability, durability, stain resistance, and cleanability.

Production & Issue Resolution: Drive root cause analysis for material-related production issues, working directly with Tier suppliers and material vendors.

Digital Validation: Provide material modeling data to support digital simulation and CAE workflows.

Supplier Collaboration: Work alongside Supplier Quality and Purchasing to evaluate, qualify, and develop material suppliers.

Technical Leadership: Apply a first-principles approach to technical challenges, demonstrate continuous learning, and embody "Rivian Compass" values.

Education: B.S. in Materials Science, Engineering, or a related field (Master’s preferred).

Experience: 5–7+ years of materials engineering experience, with a focus on mold-in-color and painted plastics (automotive experience preferred).

Material Expertise: Knowledge of decorative materials (plated components, real wood, aluminum), polymeric films, textiles, composites, or natural fibers is a plus.

Execution & Problem-Solving: Proven ability to manage multiple complex material projects, solve technical issues using first principles, and work directly with global vendors.

Communication & Detail: Strong written and verbal communication skills across cross-functional, multi-site teams; meticulous in testing documentation and data management.

* Business Acumen & Tools: Sound commercial/financial awareness, proficiency with Google Workspace, and ability to travel up to 10% (domestic and international).
