The Role

The Trading Data Technology is a new team at XTX Markets: it is responsible for the design, implementation, and operation of the firm’s Trading Data platform. The platform is an early stage / greenfield build. Its initial projects will be centred around standardising the capture of the firm’s order data, as well as how we make it available to systems and users.

This system is designed to be highly available, handling hundreds of millions of messages a day in real time. There will also be multiple forms of storage to support the platform’s various stakeholders, including kafka, column-store databases, and S3-like files.

Developers at XTX are engaged in the entire software development lifecycle of software development. Developers work closely with other teams to gather requirements, before implementing, delivering and supporting their solutions. The Trading Data Technology team will be based in London. However, stakeholders to the platform exist in multiple locations including London, New York & Singapore.

There is currently a shared support rota with the Post Trade Technology team, which includes weekend on call every 10 weeks.

Responsibilities

• Back-end services are built in Go with some additional web-based GUI development in React. Engineers at XTX adopt a tech agnostic approach, opting for the best tool for each specific task. We do not expect candidates to have prior experience in front-end programming, or Golang, but it is essential that you are open-minded to using new technologies as appropriate.
• Communicate across front and back-office teams and users of the platform to understand wider business requirements and convert them into scalable, technical solutions.
• There is currently a shared support rota with the Post Trade Technology team, which includes weekend on call every 10 weeks.

Essential Attributes

• A solid grounding in academic CS fundamentals, algorithms and data structures. Demonstrated commitment to rigorous software engineering discipline.
• Strong proficiency in a statically typed language. Prior experience with Golang is desirable, but certainly not required. Similarly, experience with front-end programming is not required.
• Desire to take ownership over projects and complex technical challenges.
• Familiarity with concurrent programming techniques and exposure to asynchronous, distributed systems.
• Understand database performance characteristics including indexing, query execution, with experience designing and optimising schemas and queries.
• Finance experience is not required, but the role will rapidly entail becoming a subject matter expert in the domain.
• We are targeting approximately 3 to 5 years’ experience. We view applications holistically and do have some flexibility around exact experience level. Please note that, whilst this role will involve significant ownership over projects; it is likely not suitable for those targeting a leadership position.
