This is a rare opportunity to shape an AI native data platform from the ground up within a scaled, well funded fintech. You will have genuine greenfield ownership, designing the foundations that enable customer facing AI products, while working in an environment that values quality, autonomy and long term impact.

The Company
They are a well established B2B fintech providing mission critical lending and decisioning software to regulated financial institutions. Backed by private equity, the business is investing heavily in R and D and is undergoing a company wide AI transformation. Operating at significant scale on highly sensitive data, they combine the stability of a mature SaaS business with the ambition and pace of a startup style AI programme.

The Role

Own the full end-to-end design of a modern, AI-native data foundation built on lakehouse principles, enabling scalable and flexible data management. This involves unifying fragmented enterprise data models into cohesive, harmonised customer and product data assets. Additionally, design and implement robust enterprise data models, along with metadata and contextual layers, ensuring that data is both accessible and interpretable for AI systems and business users alike.

  • Define data layers, governance, lineage, sensitivity classification and access controls for regulated financial data.
  • Build customer 360 views and master data capabilities to support analytics, AI agents and LLM driven use cases.
  • Lead data ingestion and mapping strategies, including batch, streaming and CDC pipelines.
  • Work as a hands on individual contributor, influencing engineering, product and leadership teams without direct authority.
  • Enable AI workspaces and data products that support customer facing AI experiences.

Your Skills and Experience

  • Strong commercial experience as a Data Architect or Principal Data Engineer within FinTech or SaaS.
  • Deep expertise in data architecture, enterprise data modelling and AI ready data platforms.
  • Hands on experience with Databricks, PySpark and Azure based lakehouse architectures.
  • Proven background in data governance, metadata management and regulatory compliance.
  • Experience designing dimensional models and modern data layers for analytical and operational use.
  • Exposure to Informatica or similar enterprise ingestion and integration tooling.
  • Confidence working with complex, sensitive financial data in regulated environments.
  • Must have eligibility to work in the U

What They Offer

  • Greenfield ownership of a strategic AI native data platform.
  • Direct access to senior leadership and influence over long term data and AI strategy.
  • The chance to build data products that directly power next generation AI capabilities.

How to Apply
If you are excited by the challenge of building an AI first data foundation within a scaled fintech, apply now by emailing resumes if interested or pass on if you know someone who'd be a great fit.

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

Where to advertise data engineering jobs UK in 2026: the specialist boards and channels that reach Spark, dbt, Snowflake and platform engineering talent. Data engineers occupy a distinct discipline that sits between software engineering, data science and cloud infrastructure — and the strongest candidates identify firmly with the data engineering community rather than with adjacent roles. General job boards consistently conflate data engineering with data analysis, data science and BI development, producing high application volumes but low candidate quality for specialist pipeline and platform roles. This guide, published by DataEngineeringJobs.co.uk, covers where to advertise data engineering 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 Engineering Jobs UK 2026: What to Expect Over the Next 3 Years

Data Engineering Jobs UK 2026: roles, salaries and the trends shaping UK data engineering hiring over the next three years — Spark, dbt, lakehouse and AI. Data engineering has become one of the most strategically important disciplines in the entire technology sector — and one of the most reliably in-demand. Every organisation that wants to use data to make decisions, train AI models, personalise products, manage risk, or understand its customers depends on data engineers to build the infrastructure that makes any of that possible. Without well-designed, reliable data pipelines, the most sophisticated machine learning model is worthless and the most ambitious analytics strategy is undeliverable. That foundational importance has made data engineering hiring remarkably resilient through the technology market corrections of the past few years. Where headcount reductions fell heavily on some engineering disciplines, demand for data engineers held firm — because the work of building and maintaining data infrastructure cannot be deferred in the way that some product development can. The data keeps coming. The pipelines need to work. But the data engineering jobs market of 2026 is not simply a stable version of what it was three years ago. The discipline has undergone a series of architectural shifts — from batch to streaming, from on-premise data warehouses to cloud-native lakehouses, from hand-rolled pipelines to declarative transformation frameworks, and most recently toward AI-augmented data engineering workflows that are beginning to reshape what the role looks like in practice. The employers hiring data engineers today are asking for a meaningfully different skill set than those hiring three years ago. The candidates who will thrive over the next three years are those who understand where the discipline is heading — which architectural patterns are becoming standard, which technologies are defining the modern data stack, and how the definition of a data engineering career is evolving toward a richer intersection of infrastructure, analytics, and AI enablement. This article breaks down what the UK data engineering 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.
