Job Description

XTX Markets is a leading algorithmic trading firm which uses state-of-the-art machine learning technology to produce price forecasts for over 50,000 financial instruments across equities, fixed income, currencies, commodities and crypto. It uses those forecasts to trade on exchanges and alternative trading venues, and to offer differentiated liquidity directly to clients worldwide. The firm trades over $250bn a day across 35 countries and has over 250 employees based in London, Singapore, New York, Paris, Bristol, Mumbai, Yerevan and Kajaani.

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 OTC Dev team is currently looking to hire an experienced developer focused on trading system development.

The Team:

  • Architects, implements and maintains a diverse set of trading systems, including prop trading on venue and OTC liquidity provision platforms across asset class (primarily Equities, FX and Crypto).
  • Receives reference implementations of models from quants, hard control requirements from Risk and Compliance, and system ergonomics requests from Trading Analysts, often working closely with those teams to find the best direction.
  • Is highly autonomous in how we work, maximising safety and velocity. We build and maintain multiple trading systems with a fraction of the headcount of our competitors, so it's critical we can eliminate bureaucracy.
  • Is composed of 10 very experienced developers from a range of backgrounds and disciplines, of which 6 currently focus on trading systems.
  • Operates entirely from our King's Cross office in London.


The Technology:

  • Consists of high-performance trading venue integrations, fair value generation, trading algorithms, risk controls and real time UIs implemented from business requirements.
  • Is predominantly implemented in Kotlin, with limited amounts of C++. Older parts of the codebase may use Python or Java, this is a decreasing minority.
  • Is tailored to a wide range of latency and throughput requirements. Where necessary we use a thread-per-core architecture, implement large parts of the network stack and integrate with network card APIs directly.

Attributes
Someone that would be an excellent fit:

  • Is an experienced coder, with a solid understanding of Computer Science fundamentals.
  • Has several years of experience working in Kotlin or other object-oriented languages like Java, C++, or C#.
  • Knows how to build technology quickly and safely using a variety of testing methods.
  • Unblocks the team with code reviews that prioritise correctness over style preferences.
  • Has experience in systems with requirements of microseconds per request or gigabits per second per thread.
  • Has experience coding to Linux APIs: Our preferred development environment is IntelliJ on Linux.
  • Is interested in financial markets but doesn't necessarily have professional experience.
  • Onsite gym, sauna, and fitness classes at no charge.
  • Extensive medical benefits including an on-site doctor and therapist at no charge.
  • Breakfast and lunch provided daily.
  • Various supports for caregivers, including emergency dependent care.
  • 25 days paid holiday per year + statutory holiday and paid sick days.
  • Generous Pension contributions.
  • We work 4 days per week in the office, 1 from home unless stated otherwise.
