Role description summaryAt SES we are passionate about taking our customers stories anywhere and we achieve this through our amazing colleagues. We’d love for you to become a valued member of our team of exceptional engineers who are working on diverse, challenging projects with many opportunities for collaboration with other teams across SES.
As our Engineer, Flight Dynamics, you will be responsible for:
- The orbital control, co-location, orbital events prediction, momentum management and propellant lifetime estimation of the SES GEO and MEO satellites
- The development of the orbital and satellite control software
- Shadowing of transfer orbit mission operations in the Flight Dynamics section
- Providing expertise for any flight dynamics related activity to other stakeholders

- 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.
- Manage large unexpected orbit perturbations or maneuver execution/ performance issues to maintain the satellite in the station-keeping window and to avoid risk of collision.
- Design develop and test software in the orbital and satellite control fields to carry out and support all the above.
- 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.
- 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
- Review and challenge the mission design for satellite launches, 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
- Providing on call support when needed
