Scientific Software Engineer (AI-based Weather Forecasting)
In recent years, AI-based weather forecasting models have demonstrated impressive speed and skill. However, most existing systems operate at relatively coarse spatial resolutions, limiting their usefulness in regions with complex terrain. Switzerland’s topography and the demand for precise, frequently updated forecasts require models that operate at very high resolution and integrate seamlessly into operational forecasting workflows.
Project background
In collaboration with Center for Climate Systems Modeling (C2SM) at ETH Zurich and various European weather centers, MeteoSwiss is leading an initiative to develop and deploy a next-generation, high-resolution AI-based weather forecasting system. The project aims to build a forecasting system capable of producing predictions across multiple temporal scales, from short-range to up to 10 days ahead, using recent advances in deep learning. A central component of this effort is Anemoi, a framework developed by the European Centre for Medium-Range Weather Forecasts (ECMWF) to support AI applications in weather and climate science.
* Join the post-processing and verification team at MeteoSwiss as a Scientific Programmer / Software Developer
* Contribute to the implementation of a state-of-the-art, ML-based forecasting system
* Focus on data processing pipelines, post-processing, and verification workflows
* Collaborate closely with scientists, ML researchers, and operational teams
* Ensure forecast outputs meet the needs of diverse users
* Support reliable integration of forecast products into production environments
* Design and implement new forecasting products
* Contribute to the evolution and long-term sustainability of the system
* Tackle complex problems and collaborate across disciplines
* Contribute across multiple stages of the workflow as the system matures
The position is limited to two years.
