Job description

At Susquehanna, quantitative researchers drive innovation from the centre of our trading floor. Leveraging expertise in probability, statistics, numerical analysis, stochastic optimisation, and machine learning, they play a pivotal role in developing and refining our trading strategies.

We are looking for PhD and research master’s students in their penultimate year of study to join our 10-week quantitative research summer internship. Run by a team of dedicated senior traders and quantitative researchers, our education programme is widely recognised as being the best in the industry. Don’t worry if you don’t come from a finance background – we will teach you everything you need to succeed.

A core strength of our internship is that our education is complemented by hands‑on trading games and project work. Interns are immersed in a real‑world algorithmic trading problem, learning about our proprietary dataspaces, novel modelling approaches, and strategy implementation.

Join us this summer to see why so many interns decide to return for a full‑time career in quantitative research.

What we're looking for
  • Research-minded: You enjoy diving deep into a question and building mathematical models to reveal patterns in vast amounts of data.
  • Analytical & detail-oriented: You approach problems with a curious and analytical mindset – building models, interpreting data, and uncovering insights with precision.
  • Clear communicator: You enjoy building relationships with those you work closely with and are comfortable sharing ideas, expressing your thoughts, and listening to the views of others.
  • Class of 2027 or 2028: PhDs (in penultimate or final year) in quantitative fields such as Mathematics, Physics, Statistics, Electrical Engineering, Computer Science, Operations Research, or Economics
What's in it for you:
  • Education: Throughout the internship you will attend classes covering a vast range of topics (Options Pricing, Machine Learning, Data Analysis Techniques, Game Theory… the list goes on!) from some of the most experienced employees in Susquehanna.
  • Collaboration: You will get to work with a wide range of people in the classroom and through your project work; people who share a passion for mathematics, problem‑solving, game theory, and technology.
  • Culture: Our non‑hierarchical, casual, and collaborative culture allows employees of every level to thrive.
  • Perks: We offer a highly competitive compensation package to our interns. Located in Ireland’s Financial Services Centre, in the heart of Dublin’s city centre, our office features free onsite catering, a games room, and a fully equipped in‑house gym. Throughout the summer, interns enjoy weekly social events. For those joining us from outside Dublin, we also provide accommodation for the duration of the internship.
