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

Where to Advertise Data Science Jobs in the UK (2026 Guide)

Where to advertise data science jobs UK in 2026: the specialist boards, communities and channels that actually reach senior and lead data science talent. Data science spans a broad and often misunderstood spectrum — from statistical modelling and experimental design through to machine learning engineering, product analytics and AI research. The strongest candidates identify firmly with specific subdisciplines and are frustrated by adverts that conflate data scientist with data analyst, business intelligence developer or machine learning engineer. General job boards produce high application volumes for data roles but consistently fail to match specialist data science profiles with the right opportunities. This guide, published by DataScienceJobs.co.uk, covers where to advertise data science roles in the UK in 2026, how the main platforms compare, what employers should expect to pay, and what the data says about hiring across different role types.

Data Science Jobs UK 2026: What to Expect Over the Next 3 Years

Data Science Jobs UK 2026: roles, salaries and the trends shaping UK data science hiring over the next three years — from MLE crossover to GenAI workflows. Data science has spent the past decade being described as the sexiest job of the twenty-first century. By 2026, the reality is both more nuanced and more interesting than that label ever suggested. The discipline has matured, fragmented, deepened, and in some respects reinvented itself — and the jobs market has changed with it in ways that create genuine opportunity for those who understand what employers actually want, and genuine difficulty for those still operating on assumptions formed five years ago. The data science jobs market of 2026 is not simply a larger version of what it was three years ago. The generalist data scientist — equally comfortable wrangling data, building models, and presenting insights to the board — is giving way to a more specialised landscape where employers know exactly what problem they are trying to solve and are looking for candidates with the specific depth to solve it. Machine learning engineering, causal inference, experimentation, AI product development, and domain-specific applied science have all emerged as distinct career tracks within what was previously a single, loosely defined profession. At the same time, the arrival of large language models and the broader AI capability wave has both threatened and created data science roles in equal measure. Some of the work that junior data scientists spent their early careers doing — data cleaning, exploratory analysis, basic model building — is being partially automated by AI tooling. But the demand for practitioners who can evaluate AI systems rigorously, apply statistical thinking to complex business problems, and build the data foundations on which AI depends has grown considerably. The candidates who will thrive over the next three years are those who understand where the discipline is heading — which specialisms are attracting the most investment, which technologies are reshaping what data scientists are expected to build and know, and how to position a data science career that will remain valuable as the field continues to evolve around them. This article breaks down what the UK data science jobs market is likely to look like through to 2028 — covering the titles emerging right now, the technologies driving employer demand, the skills that will matter most, and how to position your career ahead of the curve.
