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 Support to Science Operations Gaia. This work package is intended to provide a number of specialised services to support ESA in developing the Gaia missions Science Operations Centre at ESAC. ESAs Gaia mission is designed to create an accurate and complete astrometric catalogue which will serve for decades to come More than 1000 Million objects mostly stars in our Milky Way down to apparent magnitude 20 will be repeatedly observed from the second Lagrange point L2 during the satellites nominal lifetime of 5 years. This will yield a raw data volume of about 100 TB 1 PB total from which each stars position, trigonometric parallax, and proper motion for a smaller subset also radial velocity th will be determined to microarcsec accuracy typically 25 as for parallax at 15 magnitude. The data processing and catalogue creation is carried out by the Gaia Data Processing and Analysis Consortium DPAC formed by around 400 individuals and six main data processing centres distributed across Europe. The Gaia SOC at ESAC is an integral part of DPAC and plays a key role in designing the overall system architecture and developing and operating parts of the Core Processing systems viz. Initial Data Treatment IDT, First Look FL, and the Astrometric Global Iterative Solution. ESAC will also form the hub for data exchange via the Main Database MDB. This MDB will form the input for all processing and will be augmented with the output of all processing to arrive at a new version. The production of processing software for Gaia will continue through operations to final catalogue production around 2019. The SOC maintains core software but also receives packages from external entities to be integrated and run in SOC. The final and all intermediate catalogues will be served from ESAC and the corresponding database and access system is developed by a dedicated science archive team SAT in close cooperation with the SOC. In addition to software engineering for core SOC tasks the service is expected to cover some SATSOC interfacing and supportive work in this area. For any service provider experience in interacting with the science community would be an advantage. The selected provider must be willing render the service in a team environment and to travel. Good interpersonal and communication skills are an advantage. The service provider should be comfortable in an international working environment and be fluent in written and spoken English, one of the official languages of ESA. Service Support Positions SSCO091213 Support to Gaia Software Development and Operations. Service Specific Tasks Generic Tasks native to Software Development and Maintenance Maintain and develop and modules, applications, libraries and tools specific to SOC product generation In particular, maintain issue fixing, optimisation existing and develop new code for the common Gaia Tools Java library Optimise code infrastructure and scientific in view of runtime and memory usage Ensure timely delivery of SW releases and relative increments Perform SW architectural design as needed Prepare and maintain SW documentation Develop and maintain unit test harnesses Report on progress and problem areas Participate in the Configuration Control Boards applicable to the development and operation of the software Followingup and tracking the correction and resolution of problem reports Implement approved software enhancement requests Output and Service Performance Monitoring ESA will formally define the service delivery in terms of delivery times, performance targets and similar measurable parameters Key Performance Indicators. This shall be agreed with the service provider and shall be assessed, and modified as needed, during regular progress meetings typically monthly. The service provider shall manage the service provision and provide ESA with the necessary data and corresponding evidence. The service provider shall be measured and assessed on the basis of Periodic software releases including at least annual major releases of the software, interleaved with minor versions when applicable System and Software engineering documentation i.e. Architectural and system design, software test plan and reports Software architecture, design documentation Software documentation interfacing to user as well as developer Software source and object code Software unit tests with an approved test coverage Timely and efficient resolution of issues data, software arising Definition of Interface Control Documents ICDs and file interchange formats with external coordination units Attendance in approved groups and meetings Participation in software integration, validation, product validation and verification campaigns Progress reports Interactions Free interaction is expected with all members of the Data Processing and Analysis Consortium DPAC. Specific Qualification Requirements The service to be provided requires that the personnel should possess a university education in a scientific or technical subject and relevant professional experience in line with the requirements of the job class. In particular, possess the following experience, knowledge and proficiency in o ECSS standards for software development o JDK 1.71.8 RMI Generics o OO design o Distributed processing o Numerical programming in Java o JUnit Eclipse Ant o JDBC DBMS interaction o Subversion o Large Databasesdata processing 1TB Location It is expected that the service is provided predominantly onsite at ESAC.
