• Perform sizing of air systems (pressurization, air conditioning, anti-icing) to meet aircraft requirements.
• Model and simulate the thermodynamic performance of the system to ensure airworthiness and energy efficiency.
• Define and verify performance requirements (flow rates, pressures, temperatures) with interfaced systems and suppliers.
• Analyze the impact of technical modifications on overall performance and certification margins.
• Support flight and ground test campaigns by analysing data to correlate performance models.
• Present analysis results and design justifications to various management levels and authorities.

• Bachelor's degree in mechanical engineering, aeronautical engineering, or a related field.
• Minimum of five years of relevant experience in sizing, thermodynamics, or performance analysis of aeronautical systems.
• Proficiency in air systems (ATA 21, 30, 36) and fluid/thermal simulation tools.
• Knowledge of FAR 25/CAR 525 certification processes related to system performance.
• Ability to work autonomously in an international environment with professional proficiency in French and English.
