A leading global financial institution is undergoing a major transformation programme to prepare for mandatory U.S. Treasury clearing and the move to FICC‑sponsored repo. They're looking for a high‑calibre Senior Business Analyst with deep expertise in securities operations, repo, and regulatory change to drive delivery across a critical, high‑visibility programme.

This is a hands‑on, delivery‑focused role perfect for someone who thrives in fast‑paced environments, can work autonomously, and loves solving complex operational and systems challenges.

✅ Creating clear, structured requirements & user stories (Jira), ensuring full traceability
✅ Mapping current vs. target state and defining the full Target Operating Model (TOM)
✅ Building detailed test packs, executing testing, and supporting UAT
✅ Analysing data flows, system interactions, dependencies & operational bottlenecks
✅ Supporting readiness for clearing cycles, netting, depot transfers, and CCP obligations
✅ Acting as a bridge between Ops, Front Office, Technology, Network Management & external clearing participants
✅ Contributing to project governance, RAID management & milestone tracking

To excel in this role, you'll bring:

Strong experience in securities operations, repo, or derivatives lifecycle
A track record of delivering regulatory change, migrations, or large‑scale transformations
A BA first mindset with the ability to operate in hybrid BA/PM mode
Excellent technical literacy knowledge of data models, APIs & system behaviours
Experience working closely with Front Office, Technology & external clearing brokers
Ability to communicate clearly with senior stakeholders and influence decisions
