Engineer, Flight Dynamics

Engineer, Flight Dynamics Role description summary The Engineer, Flight Dynamics is responsible for the orbital control, co-location, orbital events prediction, momentum management and propellant lifetime estimation of the SES GEO and MEO satellites, for the development of the orbital and satellite control software and shadowing of transfer orbit mission operations in the Flight Dynamics section. Primary responsibilities Be responsible for a safe and efficient co-location and/or station-keeping of the SES GEO and MEO satellites, while minimizing propellant usage to maximize satellite lifetime, satisfying satellite constraints, and avoiding risk of collision between SES co-located satellites. This responsibility involves following activities: orbit determination, maneuver planning and computation, momentum management (part of attitude control), maneuver performance analysis and calibration.  Design, develop and test software in the orbital or satellite control fields. Manage the appropriate actions in case of large, unexpected orbit perturbations or maneuver execution or performance issues, in order to maintain the satellite in the longitude window and to avoid risk of collision.  Provide on-call support. Determine and maximize satellite propellant lifetime of SES satellites, including propellant tank management.  Provide orbit and related events predictions information to internal sections, external organization (e.g. Teleport) and customers (e.g. for ground antenna pointing, customers of hosted payload like WAAS or GOLD). Perform conjunction analysis, interface with external organization (e.g. US Air Force, satellite operators) and plan corrective maneuvers in case of close approach with another satellite or debris.  Provide on-call support in consequence. For satellites to be launched, review and challenge the mission design, shadow the implementation and lead the maneuver planning during the in-orbit test phase. Design and implement satellite re-locations to meet SES business needs, while ensuring safe separation with other satellites, minimizing propellant consumption, and coping with satellite and interference constraints.   Collaborate with Satellite Engineering to investigate satellite anomalies related to attitude control and propulsion systems. Qualifications & Experience Ability to work under own initiative and without direct supervision Capability to autonomously solve and model problems in mathematical and physics fields Ability to develop medium scale software applications Experience in Python software development is preferred Good negotiation and persuasion skills with internal stakeholders A mathematical and analytical mind Ability to react to contingencies and cope with high stress situations Excellent communication skills and team-spirit, as well as good time management and project planning skills A willingness to be self-critical and learn from…
