Systems Engineer for a navigation project | Job Details
WHAT CHALLENGE WILL YOU BE TAKING ON?
The European Space Agency’s (ESA) CELESTE programme aims to define and evaluate a new generation of satellite navigation systems based on low Earth orbit (LEO) constellations, complementing the current GNSS systems in medium Earth orbit (MEO). This programme addresses challenges relating to technology, system architecture, interoperability and the provision of high-precision, resilient and low-latency navigation services. The next phase of the programme is CELESTE In-Orbit Preparation (IOP), a large-scale project covering the end-to-end system and integrating multiple sub-programmes. The Systems Engineer role aims to take on technical responsibility for the CELESTE IOP programme, or one of its sub-programmes, leading the definition of the architecture, requirements management and technical consistency of the system.
Lead the systems engineering for the assigned programme or sub-programme.
Define and maintain the architecture of the LEO navigation system (space segment, signals, links,



ground segment and users).
Manage system requirements, including their definition, breakdown, traceability and verification.
Ensure technical consistency between the various segments and disciplines (payload, platform, navigation, ground segment, operations).
Coordinate system performance analyses.
Lead or contribute to technical reviews (SRR, PDR, CDR) in accordance with ECSS standards.
Identify and manage technical risks and design trade-offs.
Oversee the preparation of technical documentation and system models.
Liaise with ESA and other stakeholders on key technical aspects.
WHAT DO WE NEED IN OUR TEAM?
For this role, we are looking for candidates with a degree in aerospace engineering, telecommunications engineering, physics or a similar discipline. The following knowledge is also required:
Experience in systems engineering applied to complex space systems.
Solid knowledge of GNSS and navi
