Electronic Trading Support Engineer

Electronic Trading Support Engineer

Job Description

[Up to c. £250k Comp Package | Hybrid/Flexible Working]

Role Overview

We’re partnering with a highly regarded proprietary trading firm operating across global derivatives and electronic markets. The firm is seeking a senior Trade Support/Infrastructure Engineer to sit at the heart of its trading ecosystem - ensuring execution platforms, connectivity, and market infrastructure remain stable, performant, and scalable. This is not a ticket-passing support role. The successful candidate will combine strong trading domain knowledge with hands-on infrastructure expertise. You’ll work directly with traders, developers, and core infrastructure teams to diagnose and resolve production issues in real time - often owning problems end-to-end rather than escalating them...

Key Responsibilities

• Oversee the health and stability of electronic trading platforms across multiple markets and asset classes
• Act as a senior escalation point for trading-related incidents, performing deep technical investigations rather than simply routing issues onward
• Analyse order flow, execution behaviour, and exchange connectivity using logs, packet captures, and system diagnostics
• Support and optimise Linux-based production systems running latency-sensitive trading workloads
• Troubleshoot networking issues including TCP/IP stack behaviour, multicast flows, and exchange connectivity
• Work closely with trading desks to onboard new markets, venues, and strategies
• Improve monitoring, automation, and operational tooling to reduce manual intervention and increase resilience
• Partner with development teams to refine system performance, stability, and observability
• Identify recurring operational weaknesses and implement engineering-led solutions to remove root causes

What You’ll Bring…

• 5-9 years' experience in a trading support or trade infrastructure engineering role within an electronic trading environment
• Deep Linux systems knowledge, including performance troubleshooting and production debugging
• Strong understanding of networking fundamentals, particularly TCP/IP and multicast in market data and order routing contexts
• Working knowledge of FIX protocol flows and exchange connectivity
• Practical Python skills used for automation, tooling, or workflow improvement (beyond basic scripting preferred)
• Ability to trace order lifecycles and event streams using logs, diagnostics, and packet capture analysis
• An engineering-first mindset - comfortable owning issues directly and resolving them independently
• Experience operating in high-performance, low-latency environments
• Strong communication skills and comfort working directly with traders in time-sensitive situations
