XTX Markets is an algorithmic trading firm that actively trades tens of thousands of instruments on over eighty venues with a daily volume of almost three hundred billion USD. We partner with counterparties, exchanges, and e-trading venues globally to provide consistent liquidity in the Equity, FX, Fixed Income, Commodity & Options markets, helping market participants throughout the world obtain the best prices in the various assets classes we cover.

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 maximise the effectiveness of our proprietary trading algorithms. 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. We are actively seeking new methods and ideas.

At XTX Markets technology is our business and we are a diverse organisation 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 Core Engineering team will host one intern for the duration of their stay.

In Core Engineering, you will work on our technology platform supporting post-trade activities. The platform has been developed in-house using a distributed microservices architecture to provide high throughput (millions of trades per day) and high availability (24x7 operation) while also allowing very agile but well-controlled development practices (multiple production releases per day).  The primary development language for back-end services is Go, with web-based GUI development in JavaScript.

• We will give preference to candidates who are in their penultimate year of studies, preferably in a STEM subject such as Maths, Physics, Statistics, Computer Science or related.
• A solid grounding in academic CS fundamentals (algorithms and data structures) for the Core Engineer role.
• You will be enthusiastic and can demonstrate a willingness to work with multiple teams.
• You will be able to show an enthusiasm for trading, with a preference for candidates who demonstrate this with internships, personal development projects or academic study.

Please prepare a CV and covering letter and apply (here) answering all relevant questions about availability. Please indicate which team you are interested in. We can be slightly flexible on start dates, but all internships will take place in Summer 2025, and we are not able to offer off-cycle internships.

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