2. About ECMWF

ECMWF is both a research institute and a 24/7 operational service, producing and disseminating numerical weather predictions to its Member States. ECMWF carries out scientific and technical research directed to the improvement of its forecasts, collects and processes large amounts of observations, and manages a long-term archive of meteorological data. Satellite and in situ observations provide the information for up-to-date global analyses and climate reanalyses of the atmosphere, ocean and land surface.

For details, see

ECMWF has been entrusted to operate the Copernicus Atmosphere Monitoring Service (CAMS) and the Copernicus Climate Change Service (C3S) on behalf of the European Commission until the end of 2020. Copernicus is the European Union (EU) flagship Earth-observation programme. The Copernicus programme aims to ensure operational monitoring of the atmosphere, oceans, and continental surfaces, and to provide reliable, validated information services for a range of environmental and security applications.

Based on the exploitation of space based and in situ observations and models, Copernicus will provide information services for land, marine, atmospheric and climate monitoring, as well as emergency management and security.

3. Summary of the role

The C3S Climate Data Store (CDS) is the cornerstone of the C3S infrastructure. It provides Essential Climate Variables (ECVs), climate datasets, reanalyses, projections and indicators at temporal and spatial scales relevant to adaptation and mitigation strategies for various sectoral and societal benefit areas. The infrastructure will also support the provision of CAMS datasets.

Along with the data, the CDS includes a set of tools for analysing the evolution of the climate and predicting the impacts of climate change. Users of the CDS can access these tools to develop their own applications online. The CDS has been designed to support a wide range of users with different needs, by facilitating the processing of large data volumes as well as the creation of simple visualisations based on multiple data sources. CDS data and tools form the backbone of the C3S Sectoral Information System (SIS), which provides tools and applications for dealing with climate change impact in different industrial sectors, including energy, water management and agriculture.

The successful candidate will join the Climate Data Store team, located in the Copernicus Production Section of ECMWF’s Forecast Department. She/he will report to the CDS Manager and will work closely with the members of the CDS and Copernicus teams, as well as the C3S users, providers and suppliers, to develop CDS Toolbox applications through the CDS. She/he will become an expert in the understanding, use and limitations of the CDS Toolbox, to provide and maintain a high-quality data service to the end-users.

Due to the increasing number of CDS Toolbox experts (i.e. those users utilising the CDS Toolbox editor and related Python scripting language to create workflows and applications), there is a need to provide support to applications development, as a compulsory component of the C3S service. Whilst the CDS Toolbox editor has been made as user friendly as possible, it still requires a certain level of expertise in data and tools handling (the CDS datasets and the CDS Toolbox tools) to create complex workflows and applications. In addition, some ‘expert’ users (i.e. the CDS Toolbox developers) may want to add new tools into the CDS Toolbox framework, so that they can be used in workflows by other users.

4. Main duties and key responsibilities

  • Developing CDS Toolbox applications;
  • Developing and implementing (or supporting the development of) new specialised tools for the CDS Toolbox;
  • Providing support to expert users developing applications, using the CDS Toolbox;
  • Developing and implementing a process for validating applications and/or workflows developed by third parties (suppliers, service providers, users) to be added to the C3S catalogue or shared for expert communities;
  • Following-up and managing work that ECMWF may outsource to external contractors in the area of CDS applications and tools development;
  • Contributing to the definition of the mid and long-term development of the C3S toolbox functionalities;
  • Gathering and sharing relevant user needs and service feedback with the Copernicus teams;
  • Providing regular training to ECMWF/C3S technical resources (including C3S contractors and users) required to acquire an in-depth knowledge of the CDS Toolbox.

5. Personal attributes

  • Very good communication and interpersonal skills to work collaboratively with members of a small team;
  • Ability to work with subject matter experts in other fields to explain technical issues and understand their needs and translate them into deliverable requirements;
  • Very good analytical and problem-solving skills;
  • Ability to work under pressure in a time critical environment;
  • Flexible approach to adapt to changing work priorities;
  • Practical and reliable with the drive to ensure that plans are completed as efficiently as possible.

6. Qualifications and experience required


  • University degree or equivalent in a relevant subject.


  • Strong experience in geospatial data handling within a Linux and Python environment;
  • Experience with geospatial metadata and related standards.

Knowledge and skills (including language)

  • Strong working knowledge of Python fundamentals is essential;
  • Very good demonstrated knowledge of data structures and algorithms;
  • Solid knowledge of netCDF format (additional knowledge of GRIB format would be a distinctive advantage);
  • Candidates must be able to work effectively in English and interviews will be conducted in English;
  • A good knowledge of one of the Centre’s other working languages (French or German) would be an advantage.

7. Other information

The successful candidate will be recruited at the A2 grade, according to the scales of the Co-ordinated Organisations and the annual salary will be £59,228.40 net of tax.

This position is assigned to the employment category STF-PS as defined in the Staff Regulations.
