Materials Design and Reliability Engineer, Energy Products

Role details

What to Expect

Tesla is seeking a Materials Design and Reliability Engineer to support our Energy product line. You will own material design for reliability, including failure analysis, testing, proposing and implementing mitigation actions, to identify and qualify materials so our designs meet electrical, thermal, mechanical, and production requirements at the same time.

This role spans dielectric materials, adhesives, potting, encapsulation, coatings, and composite insulation systems. You will work across materials, processes, interfaces, and part geometries, using first principles to drive engineering trade-offs among reliability, manufacturability, and cost. You will integrate material degradation, long-term reliability, and manufacturing process as one engineering problem and solve it.

What You'll Do

• Lead DFMEA and PFMEA activities by identifying material-related design and process risks and driving mitigation plans
• Define and execute accelerated test methods; lead technical investigations of materials and components under aging to identify failure modes and mechanisms, including partial discharge, dielectric breakdown, delamination, hydrolysis, environmental stress cracking (ESC), and other thermo-mechanical degradation
• Characterize and evaluate adhesion, surface delamination, dielectric strength, partial discharge behavior, dielectric loss, thermal and mechanical properties, environmental robustness, and long-term reliability
• Translate application-level functional requirements into critical material properties and structure–property relationships
• Drive mitigation actions and material and process selection decisions that improve product reliability and manufacturability
• Partner with Mechanical Engineering, Electrical Engineering, Manufacturing, Quality, and Supply Chain to develop and optimize reliable prototyping and manufacturing processes for dispensing, potting, molding, encapsulation, coating, and assembly
• Help establish and review internal standards and validation methods for materials and component reliability assessments

What You'll Bring

• Degree in Polymer Science, Materials Science, Mechanical Engineering, Electrical Engineering, or a related discipline, or equivalent practical experience
• 5+ years of experience performing and leading mechanical, thermal, and reliability assessment of polymeric materials for energy storage and conversion devices, such as transformers, bushings, sensors, capacitors, cables, or power modules
• Strong understanding of polymer structure–property relationships, dissimilar-material interfacial failures, insulation degradation mechanisms, and thermo-mechanical degradation; experience with thermo-mechanical analysis or modeling of insulation systems under thermal cycling and other reliability testing is a plus
• Hands-on experience with one or more polymer processing methods: mixing, compounding, potting, casting, molding, coating, encapsulation, and impregnation
• Hands-on experience in material characterization, reliability testing, and failure analysis for elastomers, coatings, adhesives, and composites, including viscosity, rheology, hardness, physical and mechanical properties (glass transition temperature, compressive strength, tensile strength, elongation, adhesion strength etc.), coefficient of thermal expansion (CTE), thermal conductivity, and related analytical techniques
• Experience translating material behavior and failure mechanisms into practical design rules, validation plans, and process controls
• Experience working cross-functionally to solve technical problems across design, manufacturing, reliability, and supply chain
• Detail-oriented, able to work independently and in a collaborative, project-focused environment; dependable, with excellent communication skills
