Senior Materials Engineer - Metals

Rivian Rivian · Auto · Tustin, CA +2 · Quality

Senior Materials Engineer focused on ferrous metal systems (steels) with secondary support for light metals in automotive product development. Responsibilities include material selection, validation, problem-solving, defining requirements, driving failure analysis, and collaborating with cross-functional teams. Requires deep metallurgical expertise and experience navigating full product lifecycles.

What you'd actually do

  1. Lead material selection and technology development for steel and ferrous alloys on all Rivian products.
  2. Provide light-metal materials support when necessary within a broader team of metallurgical experts.
  3. Define material requirements, specifications, validation plans, and acceptance criteria for components, assemblies, and manufacturing processes involving metals
  4. Partner with design, CAE, manufacturing, quality, corrosion, durability, purchasing, and supplier development teams to ensure material performance targets are achieved
  5. Drive failure analysis and root cause investigations related to mechanical properties, microstructure, corrosion, coating performance, heat treatment, joining, and forming of metallic components.
