Battery System V&V Engineer

Outline of the Job

We’re seeking a Battery System Verification & Validation (V&V) Engineer to ensure the safety, reliability, and performance of our advanced battery systems used in electric aircraft. You will be responsible for planning, executing, and documenting verification and validation activities to comply with aviation standards and regulatory requirements.

Key Responsibility

• Validate Battery Performance by updating battery cell voltage and temperature simulation models according to real battery cell test results while accounting for various relevant inputs, e.g. SOC, SOH characteristics and discharging, charging, cooling operations
• Develop and execute verification and validation plans for battery systems (cell, module, and pack levels) used in eVTOL aircraft.
• Propose and review functional, performance, safety, and environmental testing aligned with aerospace and regulatory standards (e.g., DO-311A, RTCA standards, UN38.3, IEC 62660).
• Analyze test data and generate technical reports; identify root causes of issues and propose corrective actions.
• Collaborate with BMS engineers, design teams, system safety, and certification teams to ensure compliance with aircraft certification requirements.
• Support hazard assessments, DFMEA, and risk analysis for high-voltage battery systems.

Essential Skills

• 3+ years of experience in battery system testing, V&V, or certification (cell, module, pack, system and vehicle level).
• Strong knowledge of lithium-ion battery chemistry, high-voltage systems, and BMS (Battery Management Systems).
• Strong knowledge in Battery performance simulation models and coding.
• Proficiency in data analysis tools (MATLAB, Python, or similar).

Desirable Skills

• Experience in aerospace or aviation programs, especially with electric propulsion systems.
• Familiarity with aviation and safety standards (DO-311A, DO-160, RTCA standards, UN38.3, SAE, or EASA Part 21).
• Experience with test equipment (battery cyclers, DAQs, environmental chambers, vibration tables, etc.).
• Knowledge of airworthiness certification processes and compliance demonstration.
• Hands-on experience with Hardware-in-the-Loop (HIL) or system simulation for battery testing.

Skills for Collaborative Success

• Strong problem-solving skills with an ability to analyze complex electrical systems and propose optimized solutions.
• Excellent teamwork and communication skills, with the ability to collaborate across multidisciplinary teams.
• Those who can act on their own initiative
