# Trade Surveillance Analyst

> G MASS · London, United Kingdom · Contract · Posted 2026-07-30

**Salary:** Up to GBP 150,000

**Workplace:** on_site

## Description

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:**

-   Perform daily trade surveillance reviews, investigating potential market abuse, insider trading, and other trading anomalies across multiple asset classes.
-   Monitor and triage alerts from surveillance systems, escalating issues where necessary.
-   Conduct deep-dive investigations into trading behaviour and document findings in line with compliance procedures.
-   Maintain and refine existing surveillance scenarios and thresholds to improve detection accuracy and reduce false positives.
-   Collaborate with technology teams to optimise data feeds, logic, and infrastructure supporting surveillance tools.
-   Support data transformation projects aimed at improving automation, system scalability, and alert quality.
-   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. This is the single most important criterion for the role.
-   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 operating as the bridge between compliance and technology — writing requirements, supporting UAT, and holding technology teams to account.
-   Exposure to surveillance platforms such as Actimize or SMARTS, including scenario and rule design, alert calibration, and threshold tuning, is advantageous.
-   Curiosity and a demonstrable track record of improving the processes you inherit rather than simply operating them.

## Benefits

Salary: up to £150k

Length: 12 months, with the likelihood of extension or a strong permanent conversion pathway
