The posting

Role: Applied AI Engineer

Location: Hybrid (3 days per week in Clapham Junction)

We’re The Gym Group...

We’re one of the UK’s leading fitness businesses. With more than one million members, 265+ gyms and ambitious plans to keep growing, we’re the UK’s second-largest gym operator by membership and the fourth largest in Europe.

Our mission is simple: to break down barriers to fitness for all. We’re large enough to make a meaningful difference, but agile enough for individuals to influence how we grow. Technology, data and new ideas play a central role - and you’ll have the opportunity to take ownership, challenge how things are done and see the impact of your work.

Just as importantly, we’re a people-first business where everyone is encouraged to be themselves. We’ve been named one of The Sunday Times Best Places to Work and awarded Investors in People Gold, alongside a host of other awards recognising our culture and our people.

About the role...

This is a rare opportunity to be the first dedicated Applied AI Engineer at The Gym Group - a role with real scope, real ownership and real impact. You will build production AI solutions that change how our teams work and how our members experience fitness, working across the business as a hands-on engineer who ships code, not just ideas. If you want to shape how a major UK business adopts AI from the inside, this is the role.

What you'll be doing...

  • Designing and building production-ready agents, copilots and workflow automations that integrate with our existing systems, data and processes.
  • Embedding with business and product teams to identify, scope and deliver high-value AI solutions from prototype to production, with clear measures of success and defined handover points.
  • Contributing AI-enabled features to member-facing products alongside our Product Engineers, owning your work through deployment and incidents.
  • Evaluating and monitoring AI solutions in production and reporting impact honestly - including cost, error rates and what did not work.
  • Coaching team members while building real solutions so that capability stays with the team after each engagement, and creating reusable playbooks and standards shared across the business.
  • Working daily with the AI Platform Engineer, Tech Leads, Product Leads and AI Ambassadors to use approved models and tooling and contribute reusable components back to the platform.
  • Keeping human oversight and clear accountability at the centre of every solution, working with Information Security and Data Protection throughout.

What we're looking for...

  • Practical experience building applied AI solutions with large language models, including retrieval-augmented generation, agents and workflow automation.
  • Substantial experience building and deploying production software end-to-end, owning outcomes through deployment and support.
  • Hands-on experience with LLM APIs, prompt and context engineering, retrieval and vector search, and agent workflows involving tool use and human oversight.
  • Experience building and deploying secure solutions using cloud infrastructure, CI/CD and appropriate controls for data access.
  • Experience working directly with non-technical stakeholders to turn ambiguous problems into scoped, working solutions.
  • Proficiency in Python as a primary production language, with working knowledge of at least one additional language.
  • Experience integrating APIs, systems and data sources into existing business processes in real-world environments.
  • Experience evaluating and monitoring AI solutions in production, including observability and impact measurement.
  • A collaborative, low-ego approach and evidence of coaching others so that technical capability stays with the team.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
