System Identification Engineer

About UsHarmattan AI is a next-generation defense prime building autonomous and scalable defense systems. Following the close of a $200M Series B, valuing the company at $1.4 billion, we are expanding our teams and capabilities to deliver mission-critical systems to allied forces. Our work is guided by clear values: building technologies with real-world impact, pursuing excellence in everything we do, setting ambitious goals, and taking on the hardest technical challenges. We operate in a demanding environment where rigor, ownership, and execution are expected. About the roleEvery airframe Harmattan AI flies starts with a model. System identification turns flight data into the verified dynamics that guidance and control are designed, tuned and trained on. It is the foundation of an autopilot that adapts across multirotors, fixed wings, VTOLs and missiles. As a System Identification Engineer, working out of Paris, you will own the path from flight test to identified model. You will design and run your own experiments, build a repeatable identification pipeline, and deliver models the G&C team can trust.  Responsibilities Experiment Design & Flight Test: Plan and run your own identification tests, from excitation design to flight tests, including coordinating with the . Model Identification: Identify rigid-body, aerodynamic, propulsion and actuator dynamics using frequency and time-domain methods, including closed-loop identification on vehicles flown under a controller.
