Job description

Celeres is a high-tech company committed to the design, integration and operation of complex, mission-critical applications and systems worldwide.

We deliver turnkey projects, engineering services and product development for our customers, developing state-of-the-art systems in the Space, Aerospace, Energy, Scientific Facilities, and Defence & Security sectors. With an end-to-end approach, we manage the entire service lifecycle, from meticulous validation and ongoing maintenance to effective obsolescence management.

Celeres combines specialised engineering expertise with the capabilities and international reach of a leading technology group.

The role:

Celeres is an engineering company specialised in launch vehicle systems, including the Ariane family, as well as Ground Control & Command systems for launchers and Earth observation satellites, both civil and military.

We develop powerful, reliable and cost-effective software solutions for space transportation, Earth observation and scientific exploration missions.

We are looking for a Junior Engineer for Ground Segment Development to join our engineering team at Celeres, where we design and develop large, complex and safety-critical software applications.

You will join the project team responsible for developing a spacecraft simulator for a new European spacecraft. Working alongside experienced simulation engineers, you will contribute to the design, implementation and testing of high-fidelity simulation models representing different spacecraft subsystems, within the SIMULUS simulation environment and following the ECSS SMP (Simulation Model Portability) standard.

This is an excellent opportunity to develop your software engineering skills while gaining hands-on experience in spacecraft simulation, European space standards and mission-critical systems.
