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 recent or upcoming PhD and research master’s graduates to join our quantitative research graduate programme.  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 graduate programme is that our classroom-based education is complemented by hands-on trading games and project work. Through this work, graduates gain exposure to all phases of the work of quantitative researchers including problem conceptualisation, modelling, strategy back-testing and iteration, implementation, and monitoring.  

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.  

Soon-to-be research master’s/PhD graduate or post-doc: You have completed research in a quantitative discipline and are available to join the graduate programme in June 2026.  

What’s in it for you: 

Education: Our industry-leading education programme is designed to facilitate researchers’ transition to the world of quantitative trading. 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 graduates. 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.
