ECMWF is seeking an enthusiastic Machine Learning Scientist - ArcX Climate Change to help deliver a step change in the use of machine learning methods for sub-seasonal to seasonal prediction over Africa.
Under the EU Global Gateway programme for Africa Regional Centres of Excellence (ArcX), you will bring in the scientific and technical expertise into SEWA and ArcX-Climate Change Resilience on the use of AI/ML in sub-seasonal to seasonal forecasts time scales, in coordination with scientists and operators at African regional climate Centres (RCCs). In addition, your role will be to bridge research and innovation with specific users’ needs in an African context.
Working closely with ECMWF scientific and technical experts, as well as European and African partners, you will coordinate and contribute to research adapting Anemoi and ECMWF’s Artificial Intelligence/Integrated Forecasting System (AIFS) to produce the most skilful and reliable forecasts for weeks 3 and 4 over Africa, You will work in the Sub-seasonal Team in the Predictability Section as well as other machine learning experts across ECMWF. This will enable development of the best possible machine learning models for Africa that exploit the full potential of machine learning and high-performance computing while still being tested and evaluated by domain scientists who check for physical consistency and limits in predictability. You will also coordinate and deliver related activities, including ECMWF training focused on AI/ML in close collaboration with technical and scientific colleagues.
The role sits within the ECMWF Predictability Section. You will join a small, dynamic project team working on SEWA and ArcX within a matrix-managed structure, while collaborating widely with colleagues across ECMWF’s scientific, operational and administrative sections.
The European Centre for Medium-Range Weather Forecasts (ECMWF) is a world leader in Numerical Weather Predictions providing high-quality data for weather forecasts and environmental monitoring. As an intergovernmental organisation, we collaborate internationally to serve our members and the wider community with global weather predictions, data and training activities that are critical to contribute to safe and thriving societies.
The success of our activities depends on the funding and partnerships of the 35 Member and Co-operating States who provide the support and direction of our work. Our talented staff together with the international scientific community, and our powerful supercomputing capabilities, are the core of a 24/7 research and operational centre with a focus on medium and long-range predictions. We also hold one of the largest meteorological data archives in the world.
ECMWF has also developed a strong partnership with the European Union and has been entrusted with the implementation and operation of the Destination Earth Initiative and the Climate Change and Atmosphere Monitoring Services of the Copernicus Programme and the Strengthening Early Earning in Africa (SEWA) Programme. Other areas of work include High Performance Computing and the development of digital tools that enable ECMWF to extend provision of data and products covering weather, climate, air quality, fire and flood prediction and monitoring.
Our vision: The strength of a common goal
Our mission: Deliver global numerical weather predictions focusing on the medium-range and monitoring of the Earth system to and with our Member States
ECMWF is a multi-site organisation, with its headquarters in Reading, UK, a data centre in Bologna, Italy, and a large presence in Bonn, Germany, as a central location for our EU-related activities. ECMWF is internationally recognised as the voice of expertise in numerical weather predictions for forecasts and climate science. For more details, see www.ecmwf.int.
ECMWF has initiated a new activity in January 2026 focused on African Regional Centres of eXcellence (ArcX) on Climate Change Resilience, implemented on behalf of the European Commission DG INTPA. It runs for 4 years in partnership with the JRC and complementing other Regional Centres of Excellence in Africa, focused on Agro-ecology, Water, Ocean, Biodiversity & forest.
Activities in ArcX focus on science, technology and innovation and aim to establish a bridge with EU's Digital Agenda, including DestinE and the use of AI/ML techniques, and advancements on climate change services, including Copernicus Climate Change Service (C3S) and ClimSA. A selection of self-contained, portable "forecast-in-a-box” pilots shall be co-developed as a partnership between European and African partners, including the meteorological communities and the private sector. The applicability will be tested on its use at sub-seasonal to seasonal timescales through regional pilots and sector- and science-oriented demo cases.
The activities will come with a strong pillar on training and knowledge transfer, as well as dedicated innovation challenges, linked to ECMWF’s Code for Earth and AI Weather Quest. ArcX Climate Change Resilience builds on top of investments in digital tools and AI/ML by ECMWF and its Member States and the European Commission through DestinE. The plans support UN EW4All and WMO’s plans on the Climate Digital Innovation Hub and the Action Plan on Artificial Intelligence.
ArcX-Climate Change Resilience closely connects with ECMWF’s activities on Strengthening Early Warning in Africa (SEWA), including on AI/ML activities to deploy AIFS and other global models in an African context in support of early warnings.
Candidates must be able to work effectively in English; knowledge of one of the Centre’s other working languages (French or German) is an advantage.
If you feel that you have the relevant profile and motivation to join us but don't meet precisely all of the skills above, we still encourage you to apply!
Grade remuneration: The successful candidates will be recruited according to the scales of the Co-ordinated Organisations. Details of salary scales and allowances are available on the ECMWF website at www.ecmwf.int/en/about/jobs.
Starting date: as soon as possible.
Candidates are expected to relocate to the duty station, either to Bonn, Germany, or to Reading, UK. As a multi-site organisation, ECMWF has adopted a hybrid organisation model which allows flexibility to staff to mix office working and teleworking, including away from the duty station (within the area of our member states and co-operating states).
Interviews by videoconference (MS Team) are expected to take place within a month of the vacancy closing date.
Successful applicants and members of their family forming part of their households will be exempt from immigration restrictions.
