高级材料工程师 Sr. Materials Engineer，Thermal Management

Materials design (primary)

• Design and develop new thermal materials and the manufacturing processes that make them, starting from first-principles

• thermal performance, mass, cost, robustness, and process compatibility.
• Build process-structure-property understanding for metal thermal solutions, including alloying, sintering, joining, surface condition, porosity, and interfaces, and validate hypotheses with targeted experiments.
• Take a material from concept through launch with design, manufacturing, and supply chain partners.

Selection

• Help designers choose the best thermal material for the application by boiling the problem down to fundamental requirements and material-property relationships.

Characterization

• Provide the properties and models the analysis community needs to virtually validate designs with minimal physical testing.
• Define and lead characterization and reliability campaigns, including thermal conductivity, interface resistance, temperature cycling, damp heat, vibration, and other methods as required.
• Perform root-cause analysis of thermal-material failures using tools such as SEM, XPS, and TGA, and close the issue with an engineering solution.

Specifications and qualification

• Own material specifications that define allowable variation, inspection methods, and requirements so that material delivered to Tesla matches what was selected and characterized.
• Build processes that allow Qualification of suppliers and processes. Empowering appropriate teams to close the loop when production material drifts from the qualified state.

Issue resolution

• Own thermal-material issues on products and in the factory. Resolve emergencies quickly, then run an after-action review so the same class of problem does not recur.

Requirements:

• Master's degree or above (PhD preferred) in Materials Science, Metallurgy, Thermal Engineering, or a related field.
• Solid process-structure-property understanding. Fluent in the underlying thermodynamics, heat transfer, chemistry, and statistics.
• 3+ years developing thermal materials, not only selecting, testing, or failure-analyzing them. Metals experience strongly preferred. Proven ability to work outside the home material family when the problem requires it.
• Hands-on characterization: can design a test, run or direct the equipment, and interpret the data. Familiarity with thermal-conductivity methods (for example laser flash, ASTM D5470, ISO 22007-2) is valued.
• Able to write a specification, qualify a supplier, and defend a material selection to design and manufacturing.
• Strong communication. Manage projects independently. Influences without authority. This is not a people-manager role; you must still be able to lead technicians and vendors on characterization campaigns.
