Contract Duration: Approximately two years, with the possibility of extensions

ECMWF currently offers exciting and unique opportunities for Computational Scientists to help shape Destination Earth (DestinE) developments in collaboration with partners across Europe. These roles contribute to the provision of massively improved prediction capabilities for environmental extremes and deriving climate change adaptation measures. You will develop a web -based environment to enable researchers to create and run ultra-high-definition Earth- system workflows applicable on advanced Exascale HPC architectures, and interact with the results produced by the workflows. 

This position offers a unique opportunity for a Web Developer to design a full suite of web services for scientists to control and monitor their experiments on the Digital Twin and interact  with the results using advanced processing, rendering and visualisation techniques with a possibility of exploring immersive technologies. This open, flexible and scalable framework will be deployed on the DestinE infrastructure, offering a modern web environment and innovative tools for researchers to manage their workflows.

The successful candidate will join the Web Services Team in ECMWF’s Development Section in the Forecast Department. The team currently develops and maintains the ECMWF web services: data portals to access archived data and interactive applications to access ECMWF’s latest forecasts. You will closely work with other teams across ECMWF to produce  a successful, weather-induced extremes digital twin which is the major result of the first phase  of DestinE. 

You will also work with ECMWF’s DestinE partners ESA and EUMETSAT, interact with external contractors and contribute to communications and outreach activities with partners contributing to the DestinE implementation, stakeholders and user communities. , Contributing to progress reports to the European Commission is also part of the role.

Whilst this position is based in Bonn, Germany, there high level of interaction with staff based at the ECMWF offices in Reading, UK, and Bologna, Italy, and it is anticipated that visits to the HQ in Reading may be required.

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 34 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. For additional details, see

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.
