Data Migration Lead

Data Migration Lead

London (Hybrid)
£75,000 - £90,000 + benefits

We're partnering with a fast-growing fintech organisation building a modern, cloud-native banking platform used by financial institutions across the UK. Following continued client growth and major transformation programmes, they are looking to hire a senior data leader to own and drive data migration and broader data delivery initiatives across complex banking environments.

This is a high-impact, business-critical role sitting between data, product, and programme delivery. The successful candidate will act as the primary owner for all migration and data-related activity across client implementations, while also helping shape the wider data capability including reporting, governance, pipelines, and operational MI.

The environment is fast-paced, highly collaborative, and suited to someone who enjoys taking ownership, working directly with stakeholders, and leading from the front.

The Role

This role combines elements of:

• Data Migration Leadership
• Data Product Ownership
• Client & Stakeholder Management
• Data Delivery / Programme Leadership

You will lead end-to-end migration workstreams across banking transformation programmes, while also owning broader data responsibilities across warehousing, reporting, governance, and operational data capabilities.

The position requires someone commercially minded and highly communicative - not purely technical, and not purely project-management focused.

Key Responsibilities

Data Migration & Delivery

• Own and lead end-to-end data migration initiatives across client programmes
• Define migration strategy, governance, mapping standards, validation processes, and cutover plans
• Oversee all migration phases including discovery, mapping, reconciliation, rehearsal, cutover, and post-go-live support
• Ensure strong data quality, auditability, governance, and reporting throughout delivery
• Manage migration risks, dependencies, RAID processes, and stakeholder escalation points

Data Product Ownership

• Take ownership of broader data capabilities including:
• Data warehouse
• Data lake
• MI & reporting
• Power BI outputs
• Data pipelines
• Help shape how data is structured, governed, surfaced, and consumed internally and externally
• Work closely with engineering and product teams to define scalable data solutions
• Explore opportunities to improve automation and efficiency across data processes and apply AI-aware thinking to all areas.

Stakeholder & Client Management

• Act as the senior client-facing lead for all data-related discussions
• Translate complex technical concepts into clear, business-friendly language
• Build trusted relationships with both technical and non-technical stakeholders
• Lead workshops, delivery discussions, and governance meetings

What They're Looking For

Essential Experience

• Strong background within banking or financial services
• Proven experience leading large-scale data migration initiatives
• Experience operating in senior data leadership, data product, or programme ownership roles
• Strong understanding of:
• Data mapping
• Transformation
• Validation
• Governance
• Reconciliation
• Reporting & MI
• Experience working with cloud-based data environments and modern tooling

Soft Skills & Leadership

• Excellent communication and stakeholder management skills
• Comfortable leading clients and giving clear direction
• Able to bridge the gap between technical teams and business stakeholders
• Strong ownership mentality with the ability to operate autonomously
• Confident working in fast-moving, ambiguous environments

Nice to Have

• Exposure to Power BI and modern reporting ecosystems
• Awareness of AI/ML concepts within data platforms
• Experience working within fintech or digital banking environments

Team & Environment

• Flexible hybrid working model at the London office
• Occasional client travel for workshops or programme meetings

Package:

• £75,000-£90,000 base salary
• Annual bonus
• Equity/share scheme
• Strong pension contribution
• Private medical cover
• Electric vehicle scheme
• Hybrid/flexible working environment
