Senior Compliance Officer – Surveillance

IMC's APAC Compliance team works closely with our Trading and Technology teams to manage the regulatory risks arising from trading activity across multiple jurisdictions. As IMC expands its systematic equities business in APAC, this role will help build the surveillance coverage, controls and technical analysis needed to support that growth.

As Senior Compliance Officer - Surveillance, you will be a senior individual contributor with broad ownership of APAC trade surveillance. You will remain hands-on across surveillance strategy, alert design, data analysis and investigations, covering equities, derivatives and commodities across multiple markets. Working closely with Trading, Technology, Compliance and Legal, you will develop controls that are practical, technically robust and defensible under regulatory scrutiny.

Your responsibilities will include, but not be limited to:

• →Developing the APAC trade surveillance roadmap, with an initial focus on supporting the systematic equities expansion across new markets, products and trading strategies
• →Identifying market-abuse risks and translating new regulations, exchange updates and changes in trading activity into effective surveillance controls
• →Applying a structured investigation framework to alerts, including documenting the analysis, evidence and rationale for closure or escalation so decisions can be clearly defended
• →Designing surveillance alerts from first principles, including the scenario logic, data inputs, calculations, thresholds, exclusions, testing approach and expected outputs
• →Writing clear functional specifications and working with software developers to implement, validate and enhance alerts, data feeds and internal surveillance tooling
• →Using Python, SQL or equivalent tools to interrogate order, trade and market data; prototype analyses; test hypotheses; and assess alert performance
• →Reviewing model logic and vendor-provided surveillance, challenging systems such as OneTick or SMARTS, and developing bespoke controls where standard coverage is insufficient
• →Managing and prioritising alert queues, including high-volume scenarios, while maintaining investigation quality and improving false-positive rates without weakening risk coverage
• →Working directly with traders to understand strategies and market microstructure, assess potential misconduct and constructively challenge trading activity where required
• →Supporting responses to regulatory and exchange inquiries with clear, evidence-based analysis of trading activity

• Significant hands-on trade surveillance experience, preferably within a proprietary trading firm, market maker, HFT or systematic trading environment
• Demonstrated experience designing surveillance alerts or controls from scratch, rather than solely operating or calibrating vendor-provided scenarios
• Strong practical capability in Python, SQL or equivalent tools, including writing scripts and working independently with large order, trade and market datasets
• Ability to interrogate alert and model logic, validate outputs, identify data-quality issues and challenge technology teams or surveillance vendors with an independent view
• A clear and defensible investigation methodology, with experience distinguishing false positives from matters requiring deeper investigation or escalation
• Strong equities knowledge and a practical understanding of trading strategies, order-book behaviour and market microstructure; front-office, trading or sales-trading exposure is valuable
• Strong understanding of market-abuse typologies, including spoofing, layering, ramping, marking the close, wash trading and insider trading indicators
• Knowledge of relevant APAC regulatory and exchange requirements, such as CSRC program trading rules, the SFC Code of Conduct or ASIC Market Integrity Rules
• Experience across APAC markets, including any combination of Australia, Hong Kong, China, Japan, Korea or Singapore; experience with OneTick, SMARTS, Nice Actimize or equivalent is useful but is not a substitute for independent control design
• Ability to communicate technical surveillance logic clearly to developers and explain and defend investigation decisions to traders, senior stakeholders, exchanges and regulators
