A Spanish leader company in Aerospace Engineering and Scientific services with more than 45 years of experience working for NASA and 35 years working for ESA seeks a candidate for a System and Software Engineering for Science Operations. Work Package Overview This work package defines the tasks involved in providing service support to Mars Express MEX, ExoMars 2016 and JUICE Science Ground Segments SGS and defines the necessary tasks to be developed for the service support. All these activities are based at ESAC. Each of the Science Ground Segments of the three missions are at different stages of their lifetime, with Mars Express in operations, ExoMars in implementation and Juice in early development. The following paragraphs provide a background overview. JUICE is the first large mission of the Cosmic Vision Program to be implemented by ESA. JUICE will perform detailed investigations of Jupiter and its system components in all their interrelations and complexity, with particular emphasis on Ganymede as a planetary body and potential habitat. The investigations of the neighbouring moons, Europa and Callisto, will complete a comparative picture of the Galilean moons and their potential habitability. The mission was adopted in November 2014. The JUICE Science Operations Centre SOC, based at ESAC, is responsible for the implementation of the Science Ground Segment SGS following the requirements defined by the Project Scientist. An important task of the SOC in this early phase is to support the analysis of the operational scenarii defined by the Science Working Team during the mission development to verify the ability of the mission to deliver the expected science return within the operational constraints. ExoMars 2016 is the first mission of the ExoMars programme and it consists of a Trace Gas Orbiter plus an Entry, Descent and Landing Demonstrator Module EDM that will be launched together in January 2016 on a Proton rocket and will fly to Mars in a mated configuration scheduled for arrival after a 9month cruise phase. Three days before reaching the atmosphere of Mars, the EDM will be ejected from the Orbiter, entering the Martian atmosphere and landing on the surface of the planet. The ExoMars Trace Gas Orbiter will be inserted into an elliptical orbit around Mars and will then sweep through the atmosphere during a long aerobraking phase of several months to finally settle into a circular, 400km altitude, orbit ready to conduct its scientific mission starting in late 2017. The main objectives of this mission are to search for evidence of trace atmospheric gases that could be signatures of active biological or geological processes and to test key technologies in preparation for ESAs contribution to subsequent missions to Mars. The Trace Gas Orbiter will also serve as a data relay asset for the 2018 rover mission of the ExoMars programme until the end of 2022. The ExoMars Science Operations Centre at ESAC is responsible for the development and implementation of the SGS and thus the Science Operations and Data Handling Concept following the Science Implementation Requirements provided by the Project Scientist, This covers all the operational activities originating from the mission science objectives defined by the Science Working Team SWT including interactions with the Instrument Teams, the Russian SOC at IKI in Moscow, and the Mission Operations Centre MOC at ESOC, for the routine science operations, and ending in the generation and processing of science data that is then archived in the Planetary Science Archive PSA. The Mars Express mission was launched in June 2003 and has been providing great amounts of data since its arrival at Mars in December 2003, covering a wide range of science objectives at all levels, from the surface and subsurface geology, atmosphere dynamics and composition, up to the interaction with the magnetosphere and the characterization of the Martian system including its two moons, Phobos and Deimos. The Mars Express SOC at ESAC is responsible for the coordination of the scientific requests from the experiment teams and the implementation of the detailed science plan with the pointing and instrument observation timelines, aiming to obtain the maximum scientific return of the mission while respecting the operational constraints. We detail in what follows the different types of services required to cover the needs of all three SGSs. All services listed below are applicable on all three missions. However, not all services will be performed at the same time, as the services needs will evolve with mission and time.
