Avionic Subsystem Engineer

Company Details

SITAEL offers turn-key solutions to its customers, facilitating the access to space services and applications through Smart Microsatellite Solutions. The in-house Design and Production of Small Satellites, the leading position in the Electric Propulsion, the use of cost-effective launchers for Low Earth Orbit missions are some of the ingredients to reduce the costs of access to space. Going through all the phases of mission analysis and budget definition, SITAEL helps its Customers to make the right choices for their applications, always driven by a best value over cost criterion.



The Avionic Subsystem Engineer will act as a key reference person for the Avionic design at subsystem level, with focus on architecture and budgets, on data interfaces and data handling, on definition and configuration of data protocols, on definition of the FDIR concept and architecture, on definition of input specifications for the Avionic units (HW, SW and Firmware where applicable, with focus on Avionics ASW baseline definition for the on-board computer). After the design phase, it will either act as technical reference for the Avionic procurement (at subsystem or unit level) or as a technical reference for the Avionics HW and SW development, integration and verification. He will also support testing at the different stages of integration, by the definition of test specification, support of testing activities and review of test reports.
