Aurora is an established supplier of skilled manpower to ESA and in particular at ESTEC and ESAC. Aurora has the opportunity to expand our support within the Science and Robotic Exploration Directorate DSRE. Aurora currently has a team of 20 engineers and scientists at ESAC. ESA require a service to be provided by a software engineer with science operations experience. ESA will award the work to the company with the best proposal and Auroras existing experience on providing support to the Archive and VO team is beneficial to our commitment to produce an excellent proposal to ESA. Overview The work is to provide a number of specialised services to support ESA in System and Software Engineering at ESAC for the Science Archives and Virtual Observatory VO Team during its preparation for operations and the operational phase. The launch is planned for 2020. Euclid is an ESA mission to map the geometry of the dark Universe. The mission will investigate the distanceredshift relationship and the evolution of cosmic structures by measuring shapes and redshifts of galaxies and clusters of galaxies out to redshifts 2, or equivalently to a lookback time of 10 billion years. In this way, Euclid will cover the entire period over which dark energy played a significant role in accelerating the expansion. Within the Science Operations Departments overall responsibility for scientific operations development and execution for astronomy and solar systems missions, the Science Archives and Computer Engineering Unit carries in particular the role of developing science archives, providing easy access to mission data for the scientific community worldwide. The Science Archives Team SAT in ESAC works on various archive projects from old missions ISO, Exosat, Giotto, Smart1, Huygens, Herschel, Planck, Ulysses, current missions XMMNewton, Integral, HST, Mars Express, Venus Express, Rosetta, Soho, Cluster, Gaia and future missions BepiColombo, Euclid, LisaPF, Solar Orbiter, .... All mission science archives are available online through GUI rich client or thin client web interfaces and machine scriptable interfaces, with data distribution either online or via asynchronous FTP. Modular and flexible multitier and clientserver architecture together with the use of an objectoriented approach, Java and XML allows configurability and reuse of software systems across archive projects. Furthermore, ESA, through the ESAC SAT is playing an important role in the VO worldwide to position itself as the main VO actor for all European spacebased astronomical data. A VO is a network of interoperating data archives and software tools that use the connectivity provided by the Internet to form a scientific research environment in which astronomical research programs can be conducted. The vast astronomical archives and databases around the world, together with analysis tools and computational services, are linked together into an integrated facility, not only connecting astronomical data centres and providers but also providing collective capabilities beyond those possible in any individual archive. Within the SAT, people are usually dedicated to a specific archive project, taking care of design, implementation, operations and evolutive maintenance of the archive software systems data repository and database of products metadata, middletier applications, data distribution and interoperability, user and scriptable interfaces. As the archives software systems share a common technical framework, people assigned to one archive project can move to another archive project, ensuring easier and efficient knowledge transfer. Specific tasks would include system and software engineering tasks such as design, development, testing installation, deployment, operations and maintenance with associated documentation according to the ESA software engineering processes. Furthermore, participation to working groups, workshops, conferences and meetings where science archives and virtual observatory standards and practices are discussed might be required.
