Senior Business Analyst - Finance Transformation

London | Hybrid - 50% office based | 9-Month FTC | c.£100k - £110k

We are supporting a specialist financial services organisation looking to appoint a Senior Business Analyst to play a key role across a major Finance transformation roadmap. Sitting at the intersection of Finance, Data and Technology, you will take ownership of translating complex Finance priorities into clear, structured and delivery-ready requirements.

This is a high-visibility role suited to someone who combines strong Business Analysis capability with a Product Owner mindset and can independently drive change from initial requirements and business design through to delivery and testing.

Key Responsibilities

Lead requirements gathering, definition and documentation across a portfolio of Finance transformation initiatives.

Act as the key bridge between Finance, Data, Technology, external vendors and delivery teams.

Translate complex Finance requirements into clear, sequenced and actionable change requirements.

Own business design and review solution design documentation, ensuring proposed solutions meet Finance requirements.

Take ownership of UAT planning and execution, maintaining clear traceability between requirements and testing.

Improve delivery quality by ensuring requirements are complete, validated and signed off before development.

Work closely with senior Finance stakeholders while reducing reliance on SMEs for day-to-day delivery.

Help improve and modernise the approach to Finance change within a predominantly waterfall environment.

Experience Required

Strong Senior Business Analyst experience within Finance Transformation - this is not suited to a generic BA without significant Finance experience.

Strong understanding of Finance processes, data flows and reporting, ideally across Financial Control, FP&A and/or Treasury.

Experience operating with a Product Owner mindset, taking genuine ownership of change rather than solely documenting requirements.

Strong process and data-flow mapping skills, with the ability to visualise end-to-end processes and system interactions.

Experience working across Finance, Data and Technology teams and managing relationships with third-party vendors.

Strong stakeholder management skills with the confidence to challenge, influence and align senior stakeholders.

Experience owning UAT and testing activity through to completion.

Particularly Relevant Experience

The upcoming roadmap includes a significant General Ledger transformation, making previous GL implementation or transformation experience highly desirable. Experience improving month-end close processes would also be particularly relevant.

Experience in any of the following would also be valuable:

Finance Data & Reporting transformation, including working closely with BI/Data teams.

Treasury transformation or Treasury Management System implementations.

Workday or Oracle Finance.

Tableau or wider BI/reporting environments.

Finance automation or AI use cases.

This is an opportunity to take genuine ownership across a significant Finance change roadmap, with exposure to senior Finance stakeholders and major programmes spanning General Ledger, Finance Data & Reporting and Treasury. The initial appointment is a 9-month FTC, with potential for extension and the possibility of a longer-term permanent opportunity.
