Trade Surveillance Specialist - G MASS Consulting

G MASS Consulting are partnered with a leading Hedge Fund, as they seek a Trade Surveillance professional to join its Compliance and Surveillance team in London.

This role is ideal for someone who combines hands-on trade surveillance experience with strong data manipulation and transformation skills. The role has a combination of BAU surveillance responsibilities, as well as process and data transformation initiatives to enhance detection capabilities, data quality, and automation.

Equally important is mindset. The team is small, fast-moving, and highly commercial, and the successful candidate will be someone who takes ownership from day one, works without hand-holding, and actively looks for ways to make the surveillance framework better.

Responsibilities:

• Monitor and review daily surveillance alerts across both client-facing and proprietary business flows, ensuring timely and accurate disposition.
• Investigate potential market abuse, insider trading, and other trading anomalies across multiple asset classes, escalating issues where necessary.
• Conduct deep-dive analysis of the trading activity underpinning alerts, synthesising transactional data, market data, market context, client risk profiles, execution timing, and other potential risk factors.
• Document investigation findings in line with compliance procedures.
• Feed into and drive change initiatives to refine alert parameters, tune detection logic, and where necessary rewrite alert definitions outright - covering risk while aggressively minimising noise.
• Collaborate on the design and development of internal tooling to streamline governance, automate operational workflows, and stand up auxiliary monitoring platforms.
• Work with technology teams to optimise the data feeds, logic, and infrastructure supporting surveillance tools.
• Take ownership of process and data improvement initiatives end to end, identifying opportunities proactively rather than waiting for direction.
• Assist with periodic reviews, regulatory requests, and audit queries.
• Contribute to ongoing enhancements of the surveillance framework and data architecture.

Requirements

• A genuine ownership mindset. The team is deliberately lean and does not operate with close supervision: you will be expected to identify what needs doing, drive it to completion, and hold yourself accountable end to end.
• Hands-on experience in trade surveillance, compliance monitoring, or control functions at a hedge fund, investment bank, or asset manager.
• Understanding of global market abuse regulations and surveillance practices across asset classes.
• Strong data analysis and data manipulation capability, including SQL, with the ability to interrogate large datasets and turn findings into practical improvements.
• Demonstrated experience balancing BAU surveillance work with data transformation or enhancement projects.
• Comfortable partnering with diverse stakeholders across compliance, technology, trading, and the wider business - writing requirements, supporting UAT, and holding technology teams to account.
• Experience covering both client-facing and proprietary trading flows is strongly advantageous.
• Exposure to surveillance platforms such as Actimize or SMARTS, including scenario and rule design, alert calibration, and threshold tuning, is advantageous.
• Deep curiosity applied to data analysis, and a demonstrable track record of improving the processes you inherit rather than simply operating them.
