Senior AI Platform Engineer

UK Remote role

Salary up to £130,000 plus equity

This is a rare opportunity to join a growing SaaS business at a pivotal point in its technical evolution. They are investing heavily in AI and platform capability, looking for someone who can take ownership of agentic AI systems and shape how intelligent workflows are embedded across a complex product used by large, design-led organisations.

The Company

They are a well-established SaaS business building a platform that helps teams design, govern and scale design systems more effectively. Their software is used by global enterprises working with complex, large-scale systems. Operating as a product-led organisation, they work in small, autonomous squads and place a strong emphasis on thoughtful engineering, usability and long-term product quality.

The Role

As a Senior AI Platform Engineer, you will act as the AI and platform specialist across the engineering organisation, working closely with product, design and engineering teams. Your responsibilities will include:

  • Designing and building agentic AI workflows that integrate deeply into an existing product platform.
  • Developing systems that allow design changes to propagate intelligently across tools and documentation.
  • Working across multiple squads to embed AI capability rather than isolating it in a single team.
  • Making architectural decisions around cloud infrastructure, cost optimisation and scalability.
  • Collaborating closely with product and design to ensure AI features deliver real user value.

Your Skills and Experience

You will bring:

  • Strong commercial experience building AI-driven systems using LLM frameworks such as LangChain or LangGraph.
  • Proven experience designing or contributing to impactful platform-level engineering work.
  • A solid software engineering background, with exposure to backend systems and modern frontend frameworks such as React.
  • Experience working with cloud infrastructure, ideally AWS, and an understanding of system design and cost efficiency.
  • A product-focused mindset, with evidence of seeing features through from concept to production and iteration.

What They Offer

  • The chance to define AI capability in a product used by some of the world's largest organisations.
  • Clear technical influence and ownership in a growing engineering team.

How to Apply

If you are interested in building agentic AI systems within a product-focused SaaS environment, apply now to learn more about this opportunity.

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.
