Plan and project manage the migration across desks, including liquidity provider and venue onboarding, client migration sequencing, parallel running, cutover and decommissioning of the legacy platform.

Define and coordinate UAT with traders and Technology, including test scenarios for pricing, execution, order types, credit checks and downstream booking.

Work with Technology on FIX connectivity, integration with internal pricing, risk and booking systems, and market data requirements.

Engage Risk, Compliance and Operations on pre-trade credit controls and the regulatory and control implications of the platform change, including best execution and MiFID II reporting where applicable.

Maintain delivery plans, RAID logs and dependencies, providing progress reporting to the programme lead and steering committee.

Contribute to the wider system rationalisation programme, identifying further opportunities to simplify the eFX technology estate.

Proven experience as a Front Office Business Analyst or BA/PM within eFX, ideally on a trading platform, aggregator or vendor system implementation or migration.
