Senior Materials Engineer - Metals

About the role

The Senior Materials Engineer, Metals will lead material selection, validation, and problem solving across ferrous metal systems with secondary support for light-metal applications. This engineer must operate with meaningful autonomy, manage multiple technical inputs, and drive decisions across design, manufacturing, quality, and supply chain teams internal and external to Rivian.

Responsibilities

• Lead material selection and technology development for steel and ferrous alloys on all Rivian products.
• Provide light-metal materials support when necessary within a broader team of metallurgical experts.
• Define material requirements, specifications, validation plans, and acceptance criteria for components, assemblies, and manufacturing processes involving metals.
• Partner with design, CAE, manufacturing, quality, corrosion, durability, purchasing, and supplier development teams to ensure material performance targets are achieved.
• Drive failure analysis and root cause investigations related to mechanical properties, microstructure, corrosion, coating performance, heat treatment, joining, and forming of metallic components.
• Evaluate tradeoffs across performance, cost, manufacturability, mass, and supply base capability to arrive at best for Rivian metal technology and processing solutions.
• Support development and release of material standards, test methods, design guidelines, and best practices for engineers, fabricators, production, and service technicians.
• Review and approve supplier technical packages including material data, PPAP-related deliverables, control plans, and process capability data for key metals products.
• Translate laboratory and production findings into clear technical recommendations for engineers, program teams, and leadership.
• Influence cross-functional decisions through concise communication, strong ownership, and data-driven problem solving.

Qualifications

• Master’s degree in Materials Science, Metallurgical Engineering, Mechanical Engineering, or a closely related field.
• 5+ years of experience in automotive related product development environments.
• Experience with automotive steel sheet grades such as advanced high strength steels, HSLAs and their processing such as hot rolling, cold rolling and finishing.
• Strong metallurgical background in steels, including phase transformations, heat treatment, hardenability, microstructure-property relationships, weldability, coatings, corrosion mechanisms, and failure modes.
• Working knowledge of aluminum and other light-metal systems including casting, extrusion, sheet, forming, joining, and corrosion considerations.
• Experience supporting end-to-end product development.
• Hands-on experience with microscopy, formability testing, mechanical testing, corrosion evaluation, and interpretation of materials lab and failure analysis report data.
• Familiarity with manufacturing processes such as stamping, hemming, casting, forging, machining, welding, brazing, heat treatment, and surface finishing.
• Proven ability to independently work cross-functionally in fast-moving engineering environments.
• Strong written and verbal communication skills with the ability to explain complex technical issues clearly to varied audiences.

Preferred Qualifications

• Master’s or PhD in Materials Science, Metallurgical Engineering, or related discipline.
• Experience with automotive body, chassis, powertrain, battery enclosure, or structural component materials.
• Knowledge of AHSS, UHSS, martensitic steels, stainless steels, aluminum sheet and extrusion alloys, and associated joining strategies.
• Experience with supplier development, APQP/PPAP, DFMEA/PFMEA, control plans, and validation documentation.
• Familiarity with corrosion, environmental durability, and coating systems for vehicle applications.
• Experience developing internal material standards or design requirements.
