Our team is international with activities across the U.K., the Netherlands, North Macedonia, Belgium, Luxembourg, France, Germany, Italy and Spain.


The Candidate will provide system engineering support to the Future Missions and Instruments Division (EOP-FM) for Missions and System Studies. The tasks will include:


  • Support the definition and monitoring of activities for the preparation of future ESA Earth Observation (EO) missions, in particular for Copernicus Sentinels, new Earth Explorer/Earth Watch missions, Opportunity Missions, F-sats and Scout missions and operational meteorology missions;
  • Provide system engineering support to InCubed missions;
  • Review Technical Notes and actively participate to progress meetings and reviews related to EO future mission and system studies;
  • Support elaboration of SoWs, system requirements documents (SRD) and other applicable and reference documents for future mission and system studies;
  • Contributing to ensure the technical coherency of the system design of future EO missions, including, as needed, functional analysis and design, overall system concept, system level budgets, system performance analyses, definition of spacecraft and/or payload subsystems and related data processing, and interfaces between payload/platform and launcher and ground segment;
  • Perform internal studies for future EO missions, in particular to assess the results of external activities or to prepare the formulation of new mission concepts, including preliminary sizing of platform/payload, first estimation of the system engineering and performance budgets, with a focus on the space segment and its interfaces with the launcher and the ground segment;
  • Perform internal studies to evaluate the complementarity between ESA EO future missions and other missions (existing or planned by other space organizations), including mission analysis and assessment of potential synergy or overlap of mission capabilities.
  • Support work in the area of modelling of system or sub-system aspects for end-to-end performance simulation and system engineering tools for future EO missions.

  • At least 4 years of relevant working experience
  • Good general knowledge of ESA Earth Observation missions
  • Strong and demonstrated background in space system engineering and mission analysis, in particular for Earth Observation missions
  • Experience in space projects, preferably in the Earth Observation field and/or in preparatory activities (phase 0 and A)

  • Teamwork
  • Good communication and technical writing skills with capabilities to synthesize
  • Good organization skills
  • Methodical and proactive, with initiative and capability to work autonomously
  • Problem-solving and creativity-oriented attitude
  • Experience in space system design, mission analysis and small platform sizing is an asset
