Test Engineer, Materials Engineering

What To Expect
You will be an integral part of the Materials Engineering organization, pursuing our mission to deliver new materials and manufacturing processes that revolutionize Tesla’s products and accelerate the world’s transition to sustainable energy. As a Materials Test Engineer, you will lead materials-level testing, prototyping, characterization, test specification development, and failure analysis. The position will be based in Fremont (California, USA) at one of our three global Materials Engineering Labs.

What You'll Do

Oversee corrosion testing for a wide variety of materials, components, and vehicles across all Tesla products. Assess risk within upcoming projects and ensure applicable tests are completed within demanding project timelines

Support off-site corrosion testing, including coordination with 3rd party test providers and internal test teams, performing detailed component and vehicle inspections, and documenting findings

Design and execute experiments to characterize material properties and solve high-impact engineering challenges, while maintaining robust data-driven documentation to enable fast iteration

Perform and coordinate a wide range of materials testing and prototyping, examples can include: Environmental Aging (e.g., salt fog, UV exposure, temperature/humidity cycling, electrochemical corrosion), Material Characterization (e.g., microscopy, SEM/EDS, DSC, TGA, FTIR, profilometry, rheometry), Lab-Scale Materials and Processes prototyping, (e.g., melting, molding, heat treatment)

Validate computational models and processing–structure–property–performance relationships through rigorous experimental testing

Develop and author test specifications, aligning with both Tesla and international standards. When necessary, create and validate new test methods to improve test-to-field correlation

Lead failure analyses and root cause investigations, translating insights into design or process changes

Work with test technicians to ensure efficient setup, execution, and interpretation of results

Communicate findings clearly through detailed reports and presentations to both technical and non-technical stakeholders

Support lab operations and continuous improvement by establishing protocols, maintaining equipment readiness, and fostering a culture of safety and innovation

What You'll Bring

Degree in Materials Science, Chemistry, or a equivalent experience

2+ years of hands-on experience in materials testing, characterization, or experimental development in a lab environment

Broad knowledge of materials science principles and automotive-relevant materials: metals, polymers, composites, coatings, textiles, etc.

Proven experience with materials testing equipment, sample prep, and analysis techniques across mechanical, thermal, environmental, electrical and optical domains

Strong problem-solving skills, with a hands-on mindset and a passion for learning and innovation

Excellent communication and project coordination skills, with the ability to collaborate across disciplines and drive outcomes independently

Organized, detail-oriented, and committed to delivering high-quality data and insights under tight timelines
