Job description

G MASS Consulting is engaged by a hedge fund to identify a specialist Business Analyst to support a business-critical Bloomberg-to-Aladdin platform migration. The primary mandate is to stabilise MiFID II transaction reporting processes ahead of a September go-live, ensuring the full reporting chain - from trade capture through ARM submission to FCA output - is robust, accurate, and audit-ready.

This is not a generalist BA engagement. The client requires a hands‑on transaction reporting specialist with demonstrable end‑to‑end MiFID II delivery experience, platform migration exposure, and the ability to diagnose field‑level, logic, and control issues quickly in a live change environment.

The firm is undertaking a significant OMS migration from Bloomberg to BlackRock Aladdin. A core deliverable of this programme is ensuring that transaction reporting obligations under MiFID II are maintained without interruption and that the reporting framework is enhanced to reflect the new platform architecture. The successful candidate will join at a critical juncture; assessing the current state, identifying gaps, and driving remediation in the final stretch before go‑live.

Responsibilities

• Assess the current transaction reporting operating model during and following the Bloomberg‑to‑Aladdin migration, identifying risks and control weaknesses before they become live issues
• Map and validate the full reporting flow end‑to‑end: from trade capture and order management through to ARM submission and FCA output
• Identify and remediate breaks across field mapping, data enrichment logic, exception handling workflows, reconciliation controls, and downstream reporting outputs
• Review and challenge embedded hard‑coded and conditional logic within existing reporting processes, flagging issues that will not survive the platform transition
• Define and prioritise a remediation backlog, producing clearly structured business requirements, issue logs, and target‑state process flows aligned to go‑live timelines
• Act as the primary analytical bridge between Compliance, Operations, the trading and portfolio management business, and Technology — translating complex reporting rules into practical, actionable decisions
• Rebuild and maintain effective working relationships between compliance functions and the front‑office business where these have become strained during the change programme
• Support testing activities and UAT, ensuring reporting outputs are validated against regulatory expectations prior to go‑live
• Provide structured updates to programme leads and governance forums, maintaining clear visibility of risks, dependencies, and remediation progress

Requirements

• Strong, demonstrable MiFID II transaction reporting delivery experience, not regulatory knowledge in isolation, but hands‑on delivery of reporting change from requirement through to live operation
• Direct experience supporting OMS or platform migrations where reporting logic, field mapping, and data flows have been materially affected
• Working familiarity with the Aladdin → ARM → FCA reporting chain, including the specific data requirements, field population rules, and submission mechanics involved
• Proven ability to identify and resolve hard‑coded logic issues, conditional field capture problems, downstream reporting breaks, and exception‑handling failures
• Track record of gap analysis and remediation delivery in a regulatory reporting context, with the ability to triage issues by severity and proximity to go‑live
• Strong stakeholder management across Compliance, Operations, Technology, and front‑office or PM‑facing functions within a regulated investment management environment
• Hedge fund or broader buy‑side experience is strongly preferred; candidates from sell‑side or custodian backgrounds will be considered where buy‑side exposure is demonstrable
