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.
  • 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

Qualifications & Experience

  • Master’s degree in physics, mathematics or engineering.
  • In-depth knowledge in following specialized fields: astrodynamics, tracking systems, orbit estimation methods, orbital control of GEO and MEO satellites
  • Have a broad and comprehensive knowledge of satellite sub-systems,
  • Capable to autonomously solve and model problems in mathematical and physics fields
  • Understanding of numerical analysis and scientific software development
  • Experience in Python software development required, any additional programming language being an asset
  • Linux/Unix environment and GIT version control is preferred
  • Experience in graphical user interface development or test automation is preferred. We use PyQt5 and Froglogic’s Squish
  • Previous experience with orbital and satellite control software development is considered an asset


  • Able to work under own initiative and without direct supervision
  • Good negotiation and persuasion skills
  • Able to react to contingencies and cope with high stress situations
  • Excellent communication skills and team-spirit
  • Good time management and project planning skills
  • Willing to be self-critical and learn from mistakes
  • Eager to learn new topics, propose and take on new challenges
  • Critical thinker, able to provide constructive feedto improve processes, procedures and tools
