Execution Sales Trader - GBM Securities

Location: London

Function: Sales Trading / Electronic Execution

Role Summary

We are looking for an Execution Sales Trader to cover European and US equity markets in a front‑office, desk‑based role with flexible coverage across trading hours. The role is focused on DMA execution support, including real‑time monitoring of order flow, FIX connectivity, routing, and OMS/EMS and algorithmic execution workflows, while also handling a subset of client orders that require high‑touch execution and judgement. Working closely with brokers, technology, risk, and compliance teams, the position ensures stable market access, strong controls, and high execution standards, with scope to develop into a broader execution and flow‑trading role as the business grows.

Key Responsibilities

• DMA & Real‑Time Execution Support
  • Provide real‑time, desk‑based support, actively monitoring European and US electronic order flow throughout the trading session.
  • Ensure continuity and stability of DMA connectivity, routing configurations, and exchange access.
  • Configure and support FIX order, execution, and drop‑copy sessions.
  • Diagnose and resolve issues such as rejects, connectivity interruptions, or latency anomalies in coordination with brokers and venues.
• High‑Touch Execution
  • Handle selected European and 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.
• OMS/EMS & Platforms
  • Configure and maintain OMS/EMS workflows, routing tables, user profiles, and execution paths.
  • Work with platforms including Bloomberg EMSX/TOMS and Trafix.
  • Support UAT cycles, system upgrades, and production release testing.
• Algorithmic Execution
  • Test and validate execution algorithms (VWAP, TWAP, POV, liquidity‑seeking).
  • Monitor algorithm performance, venue selection, and routing logic during live trading.
  • Identify and elevate anomalies such as unexpected slippage or routing deviations.
• 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 elevate execution anomalies or system irregularities.
  • Work with Technology, brokers, and vendors to resolve issues efficiently.
  • Produce execution metrics, incident reports, and performance analytics.
• Client Onboarding Facilitation
  • Support the onboarding team in coordinating new client setups and ensuring a seamless end‑to‑end process.
  • Facilitate communication between front office, compliance, and operations to ensure timely completion of onboarding requirements.
  • Assist in collecting and submitting required client documentation and public record materials.
• Risk and Compliance Adherence
  • Ensure trading activities comply with internal risk limits, regulatory guidelines, and compliance standards while promoting good customer outcomes.
  • Identify, analyse and escalate potential operational or market risks, proposing solutions to mitigate exposure.
  • Collaborate with risk and compliance teams to ensure trades and positions meet applicable risk policies and frameworks.

Qualification & Experience

• Experience in equity execution trading, execution sales, or DMA support, covering both European and US markets.
• Strong understanding of DMA workflows, electronic order flow monitoring, and FIX connectivity.
• Hands‑on experience with OMS/EMS platforms such as Bloomberg EMSX/TOMS, Trafix, or comparable systems.
• Familiarity with algorithmic execution strategies and how orders are routed across exchanges, dark pools, and auction mechanisms.
• Working knowledge of pre‑trade risk controls and relevant regulatory frameworks, including FCA, SEC, and exchange rules.
• Ability to handle high‑touch orders alongside electronic execution in a fast‑paced trading environment.
• Clear communication skills and flexibility to rotate between European and US trading hours.
