Tesla is looking for a Battery Cell Simulation Engineer to develop multi-physics simulation models that connect battery cell manufacturing processes with electrochemical, mechanical, and thermal failure modes. This role involves predictive quality assurance and process optimization to enhance next-generation battery cells.

• Master’s or PhD in Mechanical Engineering, Materials Science, Chemical Engineering, Physics, or a related field, or equivalent experience
• 8+ years of experience in battery cell simulation or manufacturing process modeling (preferably in lithium-ion batteries)
• Proficiency in simulation tools such as ANSYS, COMSOL Multiphysics, Abaqus, FEniCS, or OpenFOAM
• Strong understanding of electrochemical reaction kinetics, solid-state diffusion, and thermal-mechanical behavior in battery cells
• Experience with Multiphysics coupling (thermal-electrochemical-mechanical) modeling
• Familiarity with battery cell manufacturing processes (coating, drying, calendaring, winding, sealing, electrolyte injection)
• Strong programming skills in Python, MATLAB, or C++ for automation, post-processing, and model calibration
• Demonstrated ability to interpret experimental data and use it to validate and refine simulation models

• Develop and validate finite elements (FE), computational fluid dynamics (CFD), and electrochemical-thermal (EC-TH) simulation models
• Establish digital twins of battery cell manufacturing processes to simulate process variability and its downstream effects on cell reliability
• Correlate simulation results with experimental data from lab-scale and pilot-line production
• Identify and model root causes of common failure modes such as lithium plating and internal short circuits
• Collaborate with process engineers, materials scientists, and test teams to translate simulation insights into actionable process improvements
• Lead the development of simulation-based design of experiments (DoE) frameworks to optimize manufacturing parameters

• Employees at Tesla are often offered day-one coverage with multiple medical options (some at $0 paycheck cost), dental/vision, company HSA contributions, a 401(k) match, and equity programs. Most roles also include paid time off and holidays, family-building support, employee assistance, commuter and childcare benefits, and access to discounts and wellness programs.
