What you will do

• Develop, integrate, validate, document, and release reusable component, plant, and system models for inverters, integrated power electronics, accessory power modules, onboard chargers, power inverter modules, charging systems, and high-voltage buses.
• Define model architecture, variants, initialization, signals, interfaces, and integration practices across internal, supplier, electrical architecture, controls, and co-simulation models.
• Debug model and integration issues involving voltage and current reporting, relays, precharge, derating, fault handling, thermal interactions, and charging or discharging.
• Establish model-release, regression-testing, defect-triage, documentation, standard-work, scripting, and automated workflow practices.
• Perform power-electronics and high-voltage analyses covering efficiency, losses, thermal performance, ripple, resonance, stability, EMC/EMI, transient response, and system-level behavior.
• Collaborate with engineering teams, suppliers, and program stakeholders to support design decisions, issue resolution, validation, and milestone readiness.

Requirements

• Bachelor’s degree in Electrical Engineering, Computer Engineering, or a related discipline.
• At least three years of relevant experience in power electronics, electrified vehicles, model-based engineering, simulation integration, controls, or a related technical field.
• Hands-on experience developing, integrating, validating, debugging, correlating, or releasing MATLAB/Simulink or equivalent engineering models.
• Experience with Python, MATLAB, or another scripting language for automation, analysis, data processing, or testing.
• Working knowledge of power conversion, inverter operation, electric drives, high-voltage vehicle systems, filtering, resonance, transient response, and thermal limits.
• Ability to correlate simulation results with physical-test data and apply structured root-cause analysis to product, model, software, controls, or vehicle-level issues.

Nice to have

• Master’s degree or Ph.D. in Electrical Engineering or a related discipline focused on power electronics, power systems, electric drives, power semiconductors, or systems modeling.
• Five or more years of relevant experience and knowledge of integrated power-electronics architecture, variant commonization, modularization, or reusable modeling.
• Experience with FMI/FMU, SIL, HIL, real-time simulation, virtual calibration, automated regression testing, plant models, virtual ECUs, or vehicle-level co-simulation.
• Experience with charging, bidirectional power flow, precharge, high-voltage protection, fault insertion, thermal management, EMC/EMI, supplier models, inverter firmware, controls, or calibration.
• Experience applying data analytics, optimization, or AI/ML to engineering design, validation, or virtualization.

Culture & Benefits

• Collaborative work across power electronics, controls, software, validation, electrical architecture, vehicle systems, suppliers, and global engineering teams.
• Engineering capabilities support earlier design decisions, faster issue resolution, improved prediction accuracy, and program milestone readiness.
• Benefits and total rewards support employee well-being at work and at home.
• Inclusive workplace with equal employment opportunities and reasonable accommodation support.

Hiring process

• Role-related assessments and pre-employment screening may be required where applicable.
