Lead Cell Simulation Engineer @JLR

Gaydon, GB

1.) Designed 1D–3D multi-physics simulations for Li-ion and Si-anode battery systems (P2D/P3D models) using MATLAB, Simulink, COMSOL, ABAQUS, and Star-CCM+ to predict performance, swelling, and thermal behavior under variable drive cycles and C-rates.2.) Develop and validate electrochemical-mechanical integrated models (CAE durability), combining P2D and 3D swelling simulations for stress, expansion, and safety venting studies.3.) Design thermal models and perform thermal runaway, CFD heat transfer, and gas flow analysis across cell and module architectures.4.) Execute calendar/ cycle aging and DCIR prediction models for ultra-range EV platforms (Defender, Jaguar, Range Rover); deliver validated overpotential and degradation trends.5.) Engineer cell-to-pack integration and module architecture with composite enclosures, optimized adhesives, and cooling systems achieving Cpk > 1.67 in production validation.6.) Lead cross-functional teams developing swelling-resistant casings, vent designs, and nonlinear fatigue joints; apply DFM, FMEA, PV & DV validations under Agile/JIRA frameworks.7.) Conduct battery degradation and SEI/lithium plating analyses, optimizing electrochemical parameters through cycling and calendar aging algorithms.8.) Manage NPI (Tier 1 battery cell & pack supplier consultations - A to D sample FAT, PPAP) and R&D projects integrating electrochemical, mechanical, and thermal domains — achieving and securing APC-UK grant funding for circular and recycling initiatives.9.) Skilled in system engineering, cell safety, simulation-driven design, and end-to-end battery product development from materials to pack-level validation and lead a skilled engineers in achieving system target objectives
