• Building forecasting models that solve real-world problems in the energy sector with a focus on scalability, robustness, and real-world application.
• Building data pipelines that efficiently handle large-scale, time-series data to support reliable and scalable model development and deployment.
• Exploring and analyzing data to uncover valuable insights, engineer suitable features, and improve forecasting accuracy.
• Experimenting with different techniques to optimize performance - from hyperparameter tuning to innovative algorithmic approaches.
• Implementing your models into Swissgrid’s important operational workflows, ensuring they run reliably, securely, and efficiently at scale.
• Monitoring the deployed models to track performance and handle model drift. 
• Documenting your work clearly and consistently so others can understand, track, and build on your progress - because great science is shared science.
• Collaborating across teams, engaging with stakeholders for feedback, alignment, and continuous improvement, and ensuring your work ties directly into broader business needs.

We are looking for someone who has a strong analytical mindset to develop innovative data science solutions - not someone who checks every box. But here’s what will help you thrive:

• You are studying (or recently finished) a Master’s or PhD in a relevant field like Computer Science, Artificial Intelligence, Data Science, Engineering, Mathematics, Economics, or similar.
• You have strong Python skills and have hands-on experience with MLOps tools (Scikit-learn, PyTorch, MLflow), Apache Spark, and data analytics and infrastructure platforms such as Databricks and Azure.
• You are familiar with time-series data analysis and predictive models. 
• You have a solid knowledge of Git and GitHub, such as resolving merge conflicts, and collaborating via pull requests.
• Knowledge of transmission grid operations and electricity market is a plus.
• You communicate fluently in English.

Above all, we value curiosity, a strong drive to learn, and a problem-solving mindset over prior experience and educational background. If you're eager to tackle complex data science challenges and grow in a dynamic environment, we encourage you to apply – even if you don’t meet every requirement. 

• A comprehensive look behind the scenes of the electricity industry and an understanding of its challenges, as well as in-depth insights into the development of the grid of the future
• Varied and exciting tasks within a company unique to SwitzerlandFlexible working hours as part of a motivated team
• 25–30 days of holiday, as well as company holiday between Christmas and New Year
• A state-of-the-art work environment in the immediate vicinity of Aarau railway station
• After completion of the internship, opportunities for continuing to work for the company can be discussed if desired

Swissgrid is revolutionizing the energy sector through cutting-edge automation and machine learning solutions. Our team Development & Optimization serves as the critical bridge between backoffice functions and real-time system operations, developing innovative forecast models and automation tools that directly support grid operators in their 24/7 mission.
