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.
