Über diese Senior Battery Systems Simulation & Validation Engineer Stelle bei Pivotal
About the Job
The Battery Engineering team at Pivotal is seeking a Senior Battery Systems Simulation & Validation Engineer to develop predictive battery models, define verification strategies, and correlate analytical results with laboratory and flight-test data. This role will support cell and pack development for electric aircraft and will work across battery, aeromechanical, electrical, systems, manufacturing and flight-test teams.
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.
Qualifications
-
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.
Preferred Qualifications
-
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.
Ideal Candidate
-
Uses first-principles reasoning while remaining pragmatic about schedule, hardware, and available evidence.
-
Is equally comfortable working independently on analysis and collaborating at the test article or aircraft.
-
Communicates assumptions, uncertainty, correlation quality, and technical risk clearly.
-
Thrives in rapid development cycles and converts incomplete information into focused learning plans.
