Production Support Engineer | Trading Technology | London
Our client is an exceptional global digital trading and technology business searching for a talented Production Support Engineer to join its London-based trading technology team. Operating at the forefront of digital markets and next-generation technology infrastructure, the firm supports large-scale institutional trading activity across global markets. This is a highly visible role sitting close to the trading desk, where you'll be responsible for supporting mission-critical trading and risk systems, ensuring stability, performance, and rapid issue resolution in a fast-moving front-office environment.
The ideal candidate is a technically curious engineer who thrives under pressure and enjoys getting to the root of complex production issues. You're someone who prefers investigating logs, SQL queries, system behaviour, and order flows rather than simply escalating tickets. You have experience supporting trading platforms or electronic execution environments, communicate confidently with traders and developers, and are constantly looking for opportunities to automate processes, improve monitoring, and enhance platform reliability.
