Senior Data Architect (Enterprise Data & Analytics)

La Fosse are supporting a large, complex organisation undergoing a major business separation and transformation programme, and are looking for a Senior Data Architect to take ownership of its enterprise data landscape.

This is a senior, hands-on architecture leadership role, responsible for defining and governing how data is designed, integrated, validated and reported across the organisation - both during and after separation from a parent company.

What you'll be responsible for

• Acting as the design authority for enterprise data architecture across finance, HR, payroll, planning and operational domains
• Assessing a complex, partly undocumented current-state data landscape and defining a clear target-state architecture
• Ensuring Day 1 and TSA continuity, while laying foundations for long-term modernisation
• Designing and governing data flows across SaaS platforms, cloud analytics environments and bespoke systems
• Establishing data governance, quality, lineage and standards that work across multiple vendors and platforms
• Leading data validation, reconciliation and cutover activities during separation
• Challenging and coordinating multiple SI and vendor teams
• Providing leadership and guidance to data engineers, BI developers and analysts

What we're looking for

• Strong experience in enterprise data architecture across complex, multi-system environments
• Experience across modern cloud and SaaS data technologies, such as Oracle Fusion (Finance/HR/EPM), Microsoft Azure data platforms (Fabric, Synapse, Data Lake, Power BI), and enterprise integration tools (e.g. Azure Data Factory, Oracle Integration Cloud or equivalents).
• Proven involvement in carve-outs, demergers, TSAs or large-scale transformations
• Deep understanding of data integration, modelling, analytics and governance
• Experience working with cloud data platforms and SaaS applications (tool-agnostic mindset preferred)
• Comfortable making architectural decisions with incomplete information and tight timelines
• Confident communicator able to translate complex data topics for senior stakeholders

Why this role is different

• You'll be filling a critical gap in the organisation
• You'll have genuine architectural authority, not just advisory input
• You'll shape both short-term continuity and long-term data strategy
• You'll work at the intersection of business risk, data quality and transformation

This is an excellent opportunity for a highly experienced Data Architect to contribute to a high-profile carve-out programme within a leading organisation, operating on a 12-month contract at £800 per day, outside IR35.
