Quantitative Research Internship: Summer 2025

2 days ago

Dublin, Dublin City, Ireland Susquehanna International Group Full time

Overview

We're looking for PhD and Research Masters students in the penultimate year of study to join our 2025 Quantitative Research (QR) Summer Internship. The internship is a 10-week programme offering classroom learning, together with guided research into a real-world trading problem, allowing you to apply your knowledge in probability, statistics, stochastic optimisation, numerical analysis, and machine learning as you develop your understanding of financial analytics methods.

Working from our European headquarters in Dublin, you will begin your career by being immersed in our education programme designed to bridge the gap between academic research and real-world problem solving.

Quantitative Researchers are seated at the heart of our trading floor, communicating regularly with traders seeking their insight, and connecting ideas with other quants and the technology team. Through our education programme and exposure on our trading floor, you will be equipped to dive deep into data sets and explore the statistical intricacies within the world of quantitative trading.

What we're looking for

Research Minded : You enjoy diving deep into a question and are interested in exploring the subtleties of the dynamic market conditions. You like building mathematical models to reveal patterns in the vast amount of data and love it when you discover a solution to a difficult problem.

A Communicator : You enjoy building relationships with those you work closely with. You enjoy sharing ideas, expressing your thoughts, and listening to the views of others. You're not afraid to discuss ideas and work with others to find the optimal solution.

Analytical & Detail Oriented : You prefer to explore a question with your analytical mind - crafting and fitting a model, drawing conclusions by carefully interpreting the results. You're not afraid to challenge the assumptions of your model.

Class of 2025 or 2026: You are a PhD or Research Masters student in the penultimate year of study, majoring in mathematics, physics, engineering, computer science, or econometrics. Successful interns are invited back as graduates to join our full-time graduate programme. Depending on when you graduate, you'll be invited to join the QR Programme in either January or September 2026.

What's In It For You:

Education : Throughout the internship you'll have classes covering a vast range of topics (Financial Maths, Game Theory, Tech, Trader Talks, Poker, Speaker Seminars, In-house trading games… the list goes on) from some of the most experienced employees in Susquehanna.

Development: You will get to collaborate with a wide range of people in the classroom and through your project work, allowing you to engage with others that share a similar passion for mathematics, problem-solving, trading and technology.

Culture : Our culture allows employees of every level to thrive. We buck the trend in the financial world – the environment is casual, collaborative and we focus on continuous development, no matter how long you've been in Susquehanna.

Perks : Based in Ireland's Financial Services Centre, in the heart of Dublin's city centre, our employees avail of free onsite catering, a games room, and a large in-house gym, to name but a few of our favourite perks. We organise weekly social activities throughout the summer for our interns and we'll also provide summer interns, who aren't from Dublin, with accommodation for the duration of the internship.

Our Summer Internship is 10 weeks and runs from late June to late August. Applicants must be legally eligible to work in Ireland.

Susquehanna is an equal opportunity employer, and we are committed to diversity and inclusion throughout our recruitment process. If you need assistance and/or a reasonable accommodation due to a disability during the application or recruitment process, please contact us.

Susquehanna does not accept unsolicited resumes from recruiters or search firms.
