Senior Battery Systems Simulation & Validation Engineer

About the role

Responsibilities

• Develop and maintain cell and pack-level thermal, electrical, and performance models.
• Simulate charging, discharging, heat generation, cooling, environmental exposure, aging, and off-nominal operating conditions.
• Evaluate battery performance across ambient-temperature extremes, solar loading, rapid charging, ground turnaround, and representative flight missions.
• Plan model-correlation activities and use bench, environmental, and flight-test data to improve model accuracy and engineering confidence.
• Define verification methods, and evidence for battery-system requirements.
• Define performance test objectives, test profiles, and acceptance criteria in partnership with the test team.
• Author and review engineering analyses, verification plans, test plans, test reports, and technical decision records.
• Support pack-architecture trades involving cell selection, packaging, cooling approaches, venting, sensing, and protection features.
• Analyze battery degradation, state of charge, state of health, energy capability, power capability, and thermal margins.
• Partner with the Battery Management System, electrical, and software teams on models, interfaces, diagnostics, and data quality.
• Partner with mechanical engineers on thermal-management design, structural interfaces, installation constraints, and aircraft integration.
• Identify technical risks early and recommend practical mitigation, validation, or redesign actions.
• Improve reusable simulation, data-processing, requirements-traceability, and verification workflows.

Requirements

• Bachelor's degree in Mechanical, Aerospace, Electrical, Chemical Engineering, or a related technical discipline.
• Five or more years of relevant experience in battery modeling, simulation, validation, testing, or system development.
• Experience developing equivalent-circuit and thermal models of lithium-ion cells and packs.
• Strong understanding of lithium-ion cell behavior, heat transfer, battery-pack operation, and test-data interpretation.
• Experience developing and validating engineering models against measured data.
• Proficiency with MATLAB, Python, Simulink, or comparable engineering analysis tools.
• Experience with CFD, thermal-network modeling, electrothermal modeling, or multiphysics tools such as STAR-CCM+, ANSYS, Simcenter, or COMSOL.
• Experience defining verification activities and producing clear technical documentation.
• Strong analytical, troubleshooting, and cross-functional communication skills.
• Experience with electric aircraft, electric vehicles, UAVs, aerospace systems, or other high-power battery applications.
• Experience with battery-aging, degradation, state-estimation, or mission-performance models.
• Exposure to battery abuse testing, thermal-runaway analysis, and propagation-mitigation concepts.
• Familiarity with aerospace verification, environmental qualification, requirements management, and configuration control.
• Experience with high-voltage battery systems and battery-management-system data.
