We leverage the talent of the people who work here, modern computational techniques and state-of-the-art research infrastructure to analyse large data sets across markets quickly and efficiently, to maximize the effectiveness of our proprietary trading algorithms. We are actively seeking new methods and ideas. The models that drive our trading strategies have evolved considerably over the last 10 years, from econometric methods that gave our company its name, to trees, to neural networks, to modern deep learning architectures.

XTX Markets has an unrivalled level of computational resources in the trading industry, with a growing research cluster currently containing over 25,000 GPUs with 650 petabytes of usable storage. Teams across the firm include world-class researchers with backgrounds in pure math, programming, physics, computer science and machine learning. The firm is also constructing a large-scale data centre in Finland to future-proof its significant computational capabilities.

At XTX Markets technology is our business and we are a diverse organization which attracts outstanding talent from across all industry backgrounds. We are focused on teamwork and our people collaborate on all aspects of the business, working openly and with respect for each other, our clients and the market. Our culture is non-hierarchical and one where everyone is valued. We strive for excellence in everything we do.

The Role

The finance team will host an intern for 10-12 weeks during the summer of 2026. (Flexible on start date).

In the finance team, you will have the opportunity to learn techniques for automating finance processes at scale, with hands-on  support from finance and tech professionals. You can expect a broad experience across all finance functions, engaging with several stakeholders across the business.

Process: Shortlisted candidates will be invited for 2 x 30-minute remote interviews with members of our finance team. If successful in these interviews, they will progress to an interview with our Head of FP&A. She is the person that you would report into if you were to secure an internship.

Essential Attributes

• We will give preference to candidates who are in their penultimate year of studies, preferably in a STEM or finance related subject such as Maths, Physics, Statistics, Computer Science, Economics or related.
• You should have passion for solving problems, and a demonstrable interest in data analysis. We will give a preference to candidates with coding experience, such as Python or R.
• You will be enthusiastic and can demonstrate a willingness to collaborate with multiple teams.
• You will be able to show an interest in a career in finance, with a preference for candidates who demonstrate this via their own personal development projects, previous internships or academic study.

Application Notes

Please prepare a CV and answer all questions on the application form. You’re also welcome to attach a supporting cover letter. We can be slightly flexible on start dates, but all internships will take place in Summer 2026, and we are not able to offer off-cycle internships.

We expect to receive a high volume of applications for our Summer 2026 internships. Whilst we are happy to consider your application for more than one opening, we ask that you only submit one application. We will reallocate you if appropriate based on the preferences listed on your application form.

Please Note – XTX does not run a graduate program, and the successful completion of an internship does not necessarily result in a full-time role upon graduation. We offer internships to provide insight into the inner workings of a leading algorithmic trading firm.

Applications will close on the 21^st September. If your application is shortlisted and the team would like to move forwards with an interview, you will hear back from us during the final week of September.
