Capacity to work on on-call work during critical phases (launch, commissioning) ## Description At Exotrail, we're building the technologies that make space mobility more flexible, efficient and sustainable. As part of our In-Orbit Services (IOS) division, you will contribute to the development of SpaceTower, our flight dynamics and mission operations software platform supporting spacecraft missions from mission design to in-orbit operations. As a Flight Dynamics Software Engineer, you will combine astrodynamics expertise and software engineering skills to design, develop and maintain the flight dynamics capabilities used by our teams and customers worldwide. If you enjoy solving complex orbital mechanics challenges, building reliable software products and seeing your work directly support operational space missions, we'd love to hear from you. You will contribute to the design, development and validation of Exotrail's Flight Dynamics System (FDS), supporting mission analysis, orbit determination, maneuver planning, trajectory optimization and operational flight dynamics activities. Working closely with Flight Dynamics, Software, System and Operations teams, you will deliver high-performance software solutions that support spacecraft throughout their entire lifecycle, from mission preparation to routine operations in orbit. Mission Analysis & Astrodynamics - Design and implement orbit propagation, orbit determination and maneuver planning algorithms. - Develop trajectory optimization solutions for spacecraft missions. - Contribute to mission analysis and operational flight dynamics capabilities. - Validate algorithms through simulation, testing and operational data analysis. - Translate mission requirements into robust software solutions in collaboration with multidisciplinary teams.
