• Monitor live strategy performance, distinguishing genuine signal decay from noise and normal drawdown from something broken.
• Work with engineers to improve execution logic, reduce latency, and close the gap between theoretical and realised fills.
• Manage position sizing, exposure limits, and risk controls across a live automated book.
• Investigate anomalies in fills, slippage, or venue behaviour as they happen, not after the postmortem.
