Compliance Surveillance Officer

Are you a surveillance or markets professional who has spent the last few years turning large, complex datasets into answers? Someone who investigates unusual trading, understands why a pattern looks off, and won't stop digging until the picture is clear? If you want to bring that experience to a team that pairs deep data analysis with automation to keep markets clean, and to a collaborative environment where success is shared, we'd love to hear from you.

What you’ll do

Your role in the Compliance Department at Optiver in Sydney will be crucial in ensuring adherence to regulatory requirements and best practices by leveraging expertise and driving innovation. Your key responsibilities may include:

• Investigating trade surveillance alerts end-to-end: reconstructing order and trade activity from market data, and reviewing related communications, to identify risk factors, potential market abuse and undesired conduct, and to establish what actually happened and why.
• Analysing large sets of market and trade data, using SQL, Python and AI-assisted workflows, to detect, evaluate and explain unusual trading patterns and assess potential risk.
• Building and automating detection logic, tooling and data pipelines, including AI and machine-learning driven systems, that make surveillance faster, sharper and more scalable.
