Careers in Science, research and development at Susquehanna International Group Limited


Founded in 1987, SIG has grown from an options trading firm on the Philadelphia Stock Exchange to one of the world’s largest privately held financial institutions. Today, with offices around the world, we trade almost every major financial product. We are recognised for our disciplined and quantitative trading approach and our leading-edge trading systems. Our European headquarters was established here in Dublin 16 years ago, and we now have over 400 employees working in Trading, Technology, Research, Operations, Compliance and Risk, Legal, Finance and HR.

Assistant Trader Programme

Assistant Traders work within a trading team, sourcing information that may affect trading strategies and conducting quantitative analysis of potential trading opportunities. They learn about making trading decisions, and participate in twice weekly interactive mock trading and game theory sessions, a highlight of the programme. Successful Assistant Traders are invited to enter SIG’s formal ten week training class in our global head office in Philadelphia.

Technology Associate Programme

Our software engineers design, build, maintain and support event driven systems that are fundamental to success in the changing marketplace. They are also responsible for maintaining our competitiveness in the current trading environment. The core component of the software development (TA) programme includes a three month visit to our global head office in Philadelphia. TAs participate in classroom sessions and technical rotations, working with experienced engineers on the development, delivery, support and enhancements of our trading systems and infrastructure.

Operations Analyst Programme

Our Operations Analysts are embedded in various rotations within SIG’s financial operations teams to gain in-depth knowledge of key business areas such as trade support, trading operations, settlements, equity finance and risk. The twelve month programme also incorporates classroom training sessions focused on developing company-specific knowledge and technical skills, in both our home office and our global head office in Philadelphia. At the end of the programme, our Operations Analysts will have a clear insight into SIG’s financial operations and be ready to join a team that best aligns with their skills, interests, and SIG’s business needs.


SIG offers year round internship opportunities which provide a stepping stone to becoming an Assistant Trader, Technology Associate or Operations Analyst at SIG. If you have a background in mathematics, physics, actuarial, engineering, computer science or finance, as well as exceptional analytical and probability skills and an interest in financial markets, we’d love to hear from you.
