Job description

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.

Key Responsibilities

• Investigate and resolve production incidents impacting front‑office trading, execution, and risk systems.
• Analyse logs, databases, and system metrics to identify root causes and drive permanent fixes.
• Partner directly with traders, quantitative teams, and software engineers during business‑critical incidents.
• Support order flow, market data, execution platforms, and the wider trade lifecycle.
• Enhance monitoring, observability, automation, and operational tooling to improve platform reliability and efficiency.

Key Skills

• Strong experience supporting trading, execution, OMS/EMS, market data, or front‑office technology platforms.
• Advanced troubleshooting skills across Linux/Unix environments, SQL, and production systems.
• Experience with monitoring technologies such as Geneos, Splunk, Dynatrace, or similar platforms.
• Scripting and automation skills using Python, Bash, or comparable technologies.
• Understanding of trading workflows, FIX protocol, messaging technologies, exchange connectivity, or electronic trading environments is highly advantageous.
