Procedures for personnel recruitment




Computer Analyst at EGO (Ref. TE-IT-19-1)

Context
The European Gravitational Observatory (EGO) opens a call for a one+one-year position in the context of the project ESCAPE. EGOis a French-Italian consortium founded by INFN and CNRS to foster European collaboration in gravitational wave research. EGO is located in Cascina, near Pisa, Italy and hosts the Virgo gravitational wave detector. The Virgo project involves the collaboration of about 25 laboratories with near 300 scientists, engineers and technicians from France, Italy, the Netherlands, Poland, Hungary and Spain. ESCAPE (European Science Cluster of Astronomy and Particle physics ESFRI research infrastructures) is an EU funded project in the context of the Horizon 2020 Work Program. The chief objective of ESCAPE is to establish a single collaborative cluster of next generation ESFRI facilities in the area of astronomy-and accelerator-based particle physics in order to implement a functional link between the concerned ESFRI projects and the European Open Science Cloud (EOSC).

Assignment
The successful candidate would have as a main task to develop, implement and operate, in cooperation with other participants in the ESCAPE project, the gravitational wave part of an ESFRI Science Analysis Platform (ESAP) to enhance the scientific community’s ability to access and exploit gravitational wave data and services. In particular (s)he should build, based partially on existing software, a science analysis platform that supports data discovery and integration, provides access to software and services, enables user customized processing and workflows, interfaces with the underlying distributed, large-scale computing infrastructure, and adds analytics and visualization capabilities tuned to the needs of the Gravitational Wave Antennas (GWA) (EGO/Virgo, LIGO, KAGRA etc) and other related ESFRI projects, in particular those related in the multimessenger study of the Universe (e.g. CTA, KM3Net,…).

The following are the main tasks and activities are foreseen during the project:

  • Data aggregation and staging. This task will provide users of the science platform with the capability to access and combine data from multiple collections of GWA data and stage that data for subsequent analysis;


  • Software deployment and virtualization. A key component will be the availability of readily accessible versions of the codes, tools, scripts, and packages developed by GWAs and their communities. It will include work on the containerization of software, provenance and versioning metadata, and specifically the deployment of packages available in the ESCAPE-EOSC software repository to user workspaces;


  • Analysis interface, work flows, and reproducibility. The analysis interface task combines a number of elements to form the working surface for the user of the GWA and EOSC science platforms. It integrates the data access and staging elements along with the access to the EOSC software repository and containers described in the two previous tasks into an interactive workspace. In addition, this task will provide tools and services that simplify the porting of customized analysis and processing workflows to the GWA and overall ESFRI science platform environment. Work in this task will include:

      a) the setting up and operation of functional analysis interface supporting both interactive and batch analysis jobs;

      b) the customization of the platform to several specific user scenarios incorporating experience from existing GWA and other ESFRI platform developments;

      c) the creation of tools supporting the construction of user developed workflows and pipelines including metadata;

      d) the development of representative GWA workflows based on current analysis needs; and e) the development and integration of visualization, machine learning, and advanced analysis tools into the ESAP;


  • All those tasks will require coordination with the projects and activities already ongoing in the LIGO-Virgo Collaboration in particular in the fields of: bulk data handling, multi-messenger astronomy, data-analysis tools and pipelines and public data dissemination for open science.


    Qualifications and Experience

  • Doctorate degree or equivalent in one of these fields: Physics, Astrophysics, Cosmology, Computing.
  • A few years of work experience related to computing and analysis aspects of Physics, Astrophysics, Cosmology or related subjects.
  • Good command of the English language; basic knowledge of Italian and/or French.
  • Experience with some of those technologies will be highly beneficial:
  • Containerization (such as Docker or Singularity)
  • Software development and distribution supporting tool such as: the Conda package and environment manager, the GitLab collaborative toolchain
  • File system based software distribution services such as the CernVM File System (CVMFS)
  • Distributed computing frameworks providing support for bulk data transfer, file catalog and workload management such as Dirac, Rucio and HTCondor
  • Grid middleware and services supported by EGI and OSG

  • Personal skills
    Ability to work in a team within an international and multidisciplinary environment, strong sense of team spirit and leadership capabilities.

    Vacuum Engineer (Ref. ENG-V&M-18)

    Context
    The European Gravitational Observatory (EGO) is a French-Italian consortium founded by INFN and CNRS to foster European collaboration in gravitational wave research. EGO is located in Cascina, near Pisa, Italy and hosts the Virgo gravitational wave detector.
    The Virgo project involves the collaboration of about 20 laboratories with more than 250 scientists, engineers and technicians from France, Italy, the Netherlands, Poland, Hungary and Spain.
    The vacuum system of Virgo consists of two 3 km long straight tubes, 1.2 m in diameter, and 10 vertical cylinders, called 'towers' (2 m in diameter and up to 11 m high) containing optical elements suspended to anti-seismic attenuators.
    Vacuum is needed to isolate the sensitive parts of the experiment from several disturbances directly affecting the performance of Virgo; the system has been designed and tested to reach a base pressure of 10-9 mbar after bake-out.
