    Job summary 

    ECMWF has exciting opportunities for Computational Scientists and Research Software Engineers to help shape DestinE developments in collaboration with partners throughout Europe. These roles contribute to the provision of much improved prediction capabilities for environmental extremes and for deriving climate change adaptation measures, by developing supporting software components for ultra-high definition Earth system workflows applicable on advanced Exascale HPC architectures.

    To manage its operational workflows, ECMWF and other organisations use ecFlow, a software package developed in-house for the purpose of advanced scheduling, dispatching and monitoring of tasks. It features a client-server architecture with the code-base written in modern C++ interfaced with a thin Python layer.

    This role offers a unique opportunity to develop new functionality in ecFlow and contribute to its evolution. This will include adding multi-threading capability to its server, improving server-to-server coordination and improving its Python interface. These steps will contribute to the software’s ability to work at scale, enabling the complex workflows required to support the production of the Digital Twins.

    The successful candidate will join the Software Applications Team in ECMWF’s Development Section in the Forecast Department that currently develop the software components which handle ECMWF time-critical operational workflows. They will strongly collaborate with other teams across ECMWF to ensure that workflows are correctly and efficiently served by the new architecture.

    Whilst this position is based in Bonn, Germany, there will be strong collaboration with staff based at the ECMWF HQ in Reading, United Kingdom, so it is anticipated that visits to the HQ in Reading may be required.

    Main duties and key responsibilities 
    Develop, maintain and test ecFlow server.
    Participate in planning for the future of ecFlow and ECMWF’s workflow management.
    Support the development, maintenance and testing of complex workflows for DestinE.
    Ensure the quality of service of the DestinE services.

    About ECMWF 
    ECMWF is the European Centre for Medium-Range Weather Forecasts. It is an intergovernmental organisation created in 1975 by a group of European nations and is today supported by 35 Member and Co-operating States, mostly in Europe. The Centre’s mission is to serve and support its Member and Co-operating States and the wider community by developing and providing world-leading global numerical weather prediction. ECMWF functions as a 24/7 research and operational centre with a focus on medium and long-range predictions and holds one of the largest meteorological archives in the world. The success of its activities relies primarily on the talent of its scientists, strong partnerships with its Member and Co-operating States and the international community, some of the most powerful supercomputers in the world, and the use of innovative technologies such as machine learning across its operations.

    Over the years, ECMWF has also developed a strong partnership with the European Union, and for the past seven years has been an entrusted entity for the implementation and operation of the Climate and the Atmosphere Monitoring Services of the EU’s Copernicus component of its Space Programme, as well as a contributor to the Copernicus Emergency Management Service. The collaboration does not stop there and includes other areas of work, including High Performance Computing and the development of digital tools that enable ECMWF to extend its provision of data and products covering weather, climate, air quality, fire and flood prediction and monitoring.

    ECMWF has recently become a multi-site organisation, with its headquarters based since its creation in Reading, UK, its new data centre in Bologna, Italy, and new offices in Bonn, Germany.

    It has also recently adopted a hybrid organisation model which allows its staff to mix both office working and teleworking. This generous and flexible model provides our staff with considerable flexibility to spend time outside or away from their duty station and decide how they wish to manage their professional working time at ECMWF. ECMWF is an organisation that values the whole being and both understands and values the need for flexibility in the way its staff work.

    About DestinE 
    ECMWF is a major partner in the implementation of the Destination Earth (DestinE) initiative, together with ESA and EUMETSAT as partners. The objective of the European Commission DestinE initiative is to deploy several highly accurate thematic digital replicas of the Earth, called Digital Twins.  The Digital Twins will help monitor and predict environmental change and human impact, in order to develop and test scenarios that would support sustainable development and corresponding European policies for the Green Deal.

    DestinE will thus contribute to revolutionising the European capability to monitor and predict our changing planet, complementing existing national and European efforts such as those provided by the national meteorological services and the Copernicus Services. It will be run in several phases, of which the first, the implementation phase, covers the period end-2021 – mid-2024. Future phases are foreseen (subject to funding) that will operationalise the digital twins, scale-up system production and add applications and new twin options.

    DestinE covers several demanding digital technology aspects required to develop, implement and operate the two high-priority digital twins on weather induced and geophysical extremes and on climate change adaptation. ECMWF will be responsible for the delivery of these digital twins, which will rely on complex Earth-system simulation models, data assimilation methods for fusing simulations and observations through inverse modelling and the integration of observations and models from sectors such as water and food management, renewable energies and socio-economic risk and disaster management.

    These science components require advanced digital technology solutions to maximize the efficient computing and data handling on extreme-scale infrastructures, and to adapt and operate these infrastructures across different heterogeneous architectures within a federated framework. This federated framework includes the Core Platform and Data Lake developed, deployed and operated by ESA and EUMETSAT respectively.

    The DestinE developments take forward the long-term investments of the ECMWF Member States in building a unique European prediction capability and will support the further advancement of member states services and Copernicus Services.
