A growing AI SaaS business, where data sits at the centre of everything they build, is looking for a Senior Data Engineer to take ownership of the pipelines that power their platform.

This is an opportunity to work with real world, complex data and turn it into reliable, decision ready datasets used across product, analytics and machine learning.

Python and SQL sit at the heart of the role.

The Opportunity

·You will design, build and maintain scalable data pipelines that support a fast moving AI platform. You will work closely with product, analytics and machine learning teams to ensure data is accurate, accessible and trusted.

·The business works with large volumes of imperfect and inconsistent data, so you will need to be comfortable handling edge cases, improving data quality and solving complex data challenges.

·The environment is modern and cloud based, with exposure to technologies such as Spark, Snowflake and BigQuery across AWS, GCP and Azure.

·You will also have the opportunity to support and mentor other engineers through collaboration, code reviews and sharing best practice.

·The team is supportive, highly collaborative and values different perspectives.

·Engineers are given the space to contribute ideas, challenge thinking and have a genuine impact on the direction of the platform.

Key Responsibilities

·Design, build and maintain scalable data pipelines

·Own data pipelines from source through to production

·Work with messy, incomplete and complex datasets to create clean, reliable outputs

·Improve data quality, performance and reliability as the platform scales

·Collaborate closely with product, analytics and machine learning teams

·Contribute to code reviews, engineering standards and best practice

·Support and mentor other engineers within the team

What We Are Looking For

·Strong Python and SQL expertise gained within large scale production environments

·Experience delivering complex data transformation projects end to end

·Experience with Spark, Snowflake, BigQuery or similar technologies

·Exposure to cloud environments such as AWS, GCP or Azure

·Comfortable working with large, messy and evolving datasets

·Experience taking ownership of pipelines and data engineering solutions from design through to deployment

·A collaborative approach with experience mentoring or supporting other engineers

If you enjoy building the data foundations behind AI products and want to join a business where you can have real impact, this could be an excellent 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.
