AI Engineer | Hybrid | Python | AWS | LLMs | Agentic AI

We're working with a fast-growing technology business investing heavily in AI-driven product development and intelligent automation.

They're looking for an experienced AI Engineer to help build scalable, production-grade AI systems that deliver real commercial impact across their platform.

This is not a research role. It's a hands-on engineering position focused on designing, building and deploying AI capabilities into live products used by customers globally.

You'll be working across modern AI tooling, backend engineering and cloud infrastructure to develop intelligent workflows, LLM-powered features and agentic systems that improve automation, decision-making and user experience.

What you'll be doing
  • Building and deploying production AI applications using LLMs
  • Designing agentic workflows and multi-step AI pipelines
  • Developing scalable backend APIs and cloud-native services
  • Creating RAG pipelines, embeddings and AI retrieval systems
  • Improving AI reliability through testing, evaluation and guardrails
  • Working closely with engineering, product and business teams
  • Contributing to architecture decisions and AI best practice
  • Helping shape the future direction of AI capability across the business
Tech environment

Python, AWS, APIs, LLMs, RAG, Docker, Kubernetes, microservices, cloud-native architecture and modern AI engineering tooling.

What they're looking for
  • Strong Python backend engineering experience
  • Experience building and deploying LLM-based applications
  • Good understanding of APIs, distributed systems and cloud platforms
  • Hands-on experience with RAG, embeddings and AI orchestration
  • Experience with Docker/Kubernetes and modern engineering practices
  • Someone comfortable operating in a fast-moving product environment
Nice to have
  • Experience with agentic AI frameworks
  • AI evaluation and guardrail implementation
  • Fine-tuning or hosting LLMs
  • Reinforcement learning or planning systems
  • MSc or PhD in a relevant discipline
Why apply?
  • Opportunity to work on genuinely cutting-edge AI products
  • High-impact engineering role with real ownership
  • Modern tech stack and AI-first environment
  • Fully remote flexibility
  • Strong growth plans and long-term AI investment

If you're interested in building production AI systems rather than just experimenting with them, this is a genuinely strong opportunity to join a business putting AI at the centre of its product strategy.

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.
