Principal Data Architect

Location: Remote

Salary: $210,000 - $240,000 + benefits

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 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.
