Do you have experience in Software development?, Do you have a Master's degree?, 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., * MSc or PhD in natural sciences (e.g. physics, meteorology), data science, computer science or a related field
