• Develop and optimize advanced control algorithms for high voltage battery charging and thermal management functionality
• Validate control software through SIL (Software-in-the-Loop), MIL (Model-in-the-Loop), HIL (Hardware-in-the-loop), and aircraft-level integration testing to ensure system reliability under all operating and environmental conditions
• Investigate lab, flight, and field data to troubleshoot complex issues, refine algorithms, and continuously improve charging performance
• Work closely with hardware, software, and systems engineering teams to define charge control subsystem requirements

What You Need:

• Bachelor’s or Master’s degree in Electrical Engineering, Mechanical Engineering, Aerospace Engineering, or a related technical field
• 3+ years of experience with battery management system or charge control development
• Comprehensive understanding of BMS principles, algorithms, and functionalities
• Experience with Model-Based Design tools (MATLAB/Simulink/Stateflow)
• Understanding of closed-loop control theory and thermodynamics
• Familiarity with automotive communication networks such as CAN, LIN, or Ethernet. Experience with Vector tools (e.g., CANalyzer, CANape) is highly preferred
• Self-motivated with the ability to manage and prioritize multiple tasks
• Collaborative mindset, willingness to step in and support where needed
• Passion for learning and problem solving

Bonus Qualifications:

• Understanding of battery cell chemistry behaviors and experience with electrical equivalent circuit models
