Repsol is committed to our internship program and helping students enhance their academic studies with real-world, hands-on projects. As an intern, you’ll work on real projects that deliver tangible benefits and measurable results. At the same time, you’ll have the opportunity to learn about and help to solve some of the most important issues we face. You will experience genuine teamwork, and work alongside highly qualified and experienced colleagues, while you work on live projects and operations. At the end of your internship, you will present your summer project to trading, risk, and finance leadership. Your project will be scoped within risk analytics, independent valuation, or Middle Office control automation, and is intended to produce a deliverable the desk continues to use. We encourage candidates who challenge the status quo and continuously drive improvement and innovation.

• Apply AI and machine learning techniques to energy market problems — supervised learning for price and spread forecasting, feature engineering from fundamentals and weather data, dimensionality reduction (PCA) of forward curves, and generative or simulation-based scenario construction — with appropriate attention to overfitting, validation, and model explainability in a risk control setting
• Gain exposure to the stochastic modeling of energy prices — mean-reverting and jump-diffusion processes, correlation and basis structures — and to the numerical and machine learning methods used to value physical optionality such as gas storage, transport, and tolling agreements, including Least Squares Monte Carlo and its regression-based extensions (regularized and neural network continuation-value estimation)
• Identify control gaps and enhancements to existing processes
• Liaise between internal company departments
