A leading trading firm is looking for a Front Office FIX Support Analyst to join their high-performance electronic trading technology team. This role sits directly alongside traders, quants, brokers, and external clients — perfect for someone who thrives in a fast-paced, front-office environment and has strong FIX protocol expertise.

The Role

• Provide real-time support for electronic trading systems across Equities / FX / Fixed Income (depending on client).
• Troubleshoot and resolve FIX connectivity issues, drop-copy problems, session disconnects, and trade breaks.
• Monitor order flow, executions, market connectivity, and low-latency trading behaviour.
• Work directly with traders, brokers, clients, and onboarding teams to ensure smooth trading and minimal downtime.
• Analyse logs, FIX messages, and trade data to identify root causes and prevent repeat issues.
• Support client onboarding, certification, and testing of new FIX flows.
• Collaborate with development and infrastructure teams to deploy upgrades, patches, and environment changes.
• Support end-to-end order routing, algo behaviour, and market venue integrations.

What We're Looking For

• Strong understanding of FIX protocol (4.2/4.4) — message types, tags, order lifecycle.
• Experience supporting electronic trading systems within a bank, broker, hedge fund, or trading venue.
• Ability to read logs, parse FIX messages, and troubleshoot connectivity issues confidently.
• Knowledge of order management, market microstructure, and the trade lifecycle.
• Strong problem-solving skills and ability to work under pressure in a front-office environment.
• Exposure to Linux/Unix, SQL, scripting (Python/Shell), or monitoring tools is a plus.
• Clear, concise communication for working with traders and external clients.
