Research Software Engineer – ML Framework Development

The role 

We are in search of a highly motivated Research Software Engineer (A2) to work with ECMWF’s Member States on the next generation of machine-learned weather forecasting models. This role is an integral part of a dynamic team, consisting of scientists and software engineers contributing to building ECMWF’s next generation of weather forecasting systems. 

At ECMWF, you will join a passionate community collectively aiming to bring novel technology and science to the cutting-edge of numerical weather prediction. With the recent breakthrough in Artificial Intelligence (AI) and the progress made in AI-driven weather forecasting, it becomes clear that AI will play a key role in the next generation of forecasting systems. To this end, ECMWF built a dedicated multi-disciplinary group to tackle these challenges. ECMWF has been the first operational weather centre to publish results of its own global machine-learned weather model – the Artificial Intelligence Forecasting System (AIFS). 

We are working with our Member States to build a high-level machine learning framework to train data-driven weather forecasting models, called Anemoi . For ECMWF, the AIFS is one possible product from this system, which will enable meteorological organisations to provide data sources and recipes to train forecasting models. This concept has already been demonstrated . 

In this role, you will work closely with our Member States and provide them with support to build machine-learned forecasting models tailored to their needs. You will also gather feedback and requirements to improve the ECMWF software stack. The position may require frequent travels to our Member States and work closely with their teams to develop and improve their machine-learned tools and workflows. 

The team

The role sits in the Data Processing Services Team, within the Development Section in the Forecasts and Services Department. The team ensures the scalability, performance, and robustness of the operational weather forecasting pipeline. Effort is dedicated to navigating challenges posed by future model upgrades. This is done by exploring new technology, such as accelerators and novel storage hardware, and new algorithmic methodologies, including machine learning. We aim to be ahead of the curve, in order to maintain ECMWFs world-leading position for global weather prediction. 

About ECMWF 

The European Centre for Medium-Range Weather Forecasts (ECMWF) is a world-leader in weather and environmental forecasting. As an international organisation we serve our members and the wider community with global weather predictions and data that is critical for understanding and solving the climate crisis. We function as a 24/7 research and operational centre with a focus on medium and long-range predictions, holding one of the largest meteorological data archives in the world. The success of our activities builds on the talent of our scientists and experts, strong partnerships with 35 Member and Co-operating States and the international community, some of the most powerful supercomputers in the world, and the use of innovative technologies and ML across our operations. 

ECMWF has also developed a strong partnership with the European Union and has been entrusted with the implementation and operation of the Climate Change and Atmosphere Monitoring Services of the EU Copernicus Programme. We also contribute to the Copernicus Emergency Management Service. 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.

ECMWF is a multi-site organisation, with a main office in Reading, UK, a data centre/supercomputer in Bologna, Italy, and a large presence in Bonn, Germany. While we expect staff to relocate to the duty station we appreciate the need for flexibility in the way our staff work – and allow a staff to alternate office and telework up to 10 days/month.
