Starion Group

Starion is a European engineering services company providing expertise for space, defence and other critical infrastructures. Its services cover the complete satellite lifecycle — space systems engineering, space security, ground segment systems, mission operations, Earth observation, space science and positioning, navigation and timing — alongside digital engineering capabilities such as data engineering, concurrent design and model-based systems engineering (MBSE). The company cites over three decades of experience in professional engineering services, is part of CS Group, and in April 2026 was acquired by Sopra Steria as part of a move to create a leading European player in the space and cybersecurity sectors.

In Spain, Starion has an office at Edificio Madrid 92 in Las Rozas de Madrid, and its careers site lists vacancies filtered by Spain location, currently including a Space Weather Engineer role. The company actively invites candidates from across Europe to join its teams and accepts open applications from those whose skills do not match a listed vacancy, which is relevant for international professionals targeting Spain's space sector.
