- Monitor algorithm performance, venue selection, and routing logic during live trading.
- Identify and escalate anomalies such as unexpected slippage or routing deviations.
- High-Touch Execution
- Handle selected US equity orders requiring manual oversight or execution discretion.
- Provide intraday liquidity insight, execution strategy considerations, and market colour.
- Coordinate with brokers, venues, and dark/auction mechanisms to support best execution.
- Risk & Controls (in close cooperation with Risk team)
- Configure and maintain pre-trade risk checks (max order size, price collars, credit limits, restricted lists).
- Participate in market access testing, exchange certification, and periodic control reviews.
- Ensure adherence to SEC, FINRA, exchange rules, and FCA compliance standards.
- Monitoring & Reporting
- Investigate and escalate execution anomalies or system irregularities.
- Work with Technology, brokers, and vendors to resolve issues efficiently.
- Produce execution metrics, incident reports, and performance analytics.
Qualification & Experience
- 3–7+ years of experience in DMA, electronic trading support, FIX connectivity, or execution services.
- Strong understanding of US equities market structure, including Reg NMS, dark pools, routing, and auctions.
- Proficiency with FIX protocol (4.x) and diagnosing FIX workflow issues.
