QUANTITATIVE STRATEGIST INTERNSHIP Virtu's internship program offers graduate students an extraordinary opportunity to learn about the firm and the world’s financial markets. We have built a thoughtful and challenging curriculum with projects that introduce students to the many complex and ever changing problems to solve. Students can expect a company-curated global training week for our interns, real quantitative problems to solve throughout the program and engaging social events to get to know our team and culture. Location : Dublin Dates: 10 week program, 21 June 2027 - 27 August 2027 (with flexibility if needed) Training : Ongoing training throughout the summer Projects : Interns will work on real-world research and engineering problems throughout the program. Students will select from a portfolio of projects and receive mentorship from several senior team members. Projects may span quantitative research, algorithm development, machine learning, and deep learning applications for trading and market analysis. Perks : Daily catered lunches, onsite gym & workout classes, onsite barista, laundry service, breakfast & lunch, games room Our Quantitative Strategists and Researchers are an integral part of the algorithmic research team, working to improve Virtu's trading algorithms by transforming large data sets into robust trading models. Successful researchers enjoy working both independently and collaboratively, are excited to learn and apply modern quantitative, machine learning, and deep learning techniques, and are motivated by seeing their ideas translated into real production systems. Interns will work directly with senior members of the team on research that supports Virtu's customer market making business. Depending on the project, interns may apply quantitative analysis, statistical modeling, machine learning, or deep learning techniques to identify patterns in large-scale trading data and develop models that improve our trading algorithms. Through these projects, interns will gain exposure to market making, work with large and complex datasets, and be encouraged to think creatively about novel research ideas. Each intern will complete one or two projects, potentially working with different mentors and research groups.
