Provn are proud to be partnered with an international investment manager as they look to hire an Business Analyst to join their technology transformation programme.
Our client currently delivering a major systems transformation, migrating from legacy platforms. It’s a genuinely large-scale programme: alongside the current migration, the client has a further system upgrade and two additional migrations planned for 2028, meaning this is the start of sustained transformation work rather than a single, isolated project.
The role sits across two strands. First, mapping legacy workflow and integration points as the business transitions to the new platform - understanding how systems currently talk to each other and defining what needs to happen in the new world. Second, working directly with business users on the specifications.
Key Responsibilities
- Produce business requirements documents for legacy system integration points
- Map current-state workflow and integration points, and define what’s required to replicate or improve them in the target platform
- Work directly with technical SMEs to define specifications
- Translate business requirements into clear, testable specifications for delivery teams
- Build and maintain relationships with business stakeholders across the organisation
- Support the wider migration programme in identifying and de-risking legacy integration dependencies
- Work alongside other integration BAs on the programme, contributing to a shared, consistent approach
- Provide input into programme-level planning as scope expands across future migrations
Role Requirements
- Proven senior BA experience producing business requirements documents for system-to-system data integrations
- Experience with data warehousing, data migration, or legacy-to-target integration mapping
- Confidence working to data item level detail alongside business and technical stakeholders
- Experience with regulatory systems
Why Apply
- Join a large-scale, multi-year transformation programme at an early, high-impact stage
- Direct exposure to a newly implemented enterprise data platform — rare experience in the UK market
- Genuine potential for extension beyond the initial six months as the programme scope grows
- High-visibility role working directly with actuaries and senior business stakeholders
This is a chance to shape a platform that’s still actively growing, with genuine ownership over technical direction rather than just execution.
