What you will gain from this experience

We have an exciting 2-month summer Internship opportunity that will provide hands-on experience within our Global Asset Allocation (GAA) Team in Madrid.

Interns will contribute directly to the Systematic/Quantitative pillar of the team, supporting the development of systematic investment models and tools used in multi-asset portfolio construction and monitoring.

You will gain exposure to real investment processes, learn how quantitative research is translated into robust, production-grade tools, and collaborate closely with experienced quants on a broad range of initiatives—from research and backtesting to automation, reporting, and scalable implementation within our Strategic and Tactical Asset Allocation (SAA and TAA) activities.

Internship location

Based in Madrid, you will become part of an international business working with teams across different geographies.
