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.
