We're The Gym Group, one of the UK's leading fitness businesses. Our mission is simple: to break down barriers to fitness for all. 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.

What you'll be doing...

  • Creating SDKs, APIs, prompt libraries, agent harnesses and golden paths that make AI-native engineering the easy default for our technology teams.
  • Building and running the shared AI platform: model access and routing, identity, secrets, monitoring and connectors to enterprise data and collaboration systems.
  • Building the integrations and shared context that make enterprise AI services genuinely useful to colleagues across the business, with access that respects existing permissions.
  • Designing and implementing technical guardrails and security controls - including audit logging, data isolation and action limits for agentic use - rather than relying on policy alone.
  • Providing cost, usage and vendor visibility, and planning for model and provider change so we are never locked in to a single dependency.
  • Partnering with the Applied AI Engineer, Tech Leads and AI Ambassadors to turn recurring needs into reusable platform capabilities.
  • Keeping the platform to clear reliability and recovery standards, with observability, alerting and runbooks maintained with Site Reliability Engineering.
  • Documenting what you build and sharing ownership across the team so the platform never depends on one person.

What we're looking for...

  • Practical, hands-on experience with AI tooling in production: coding agents, enterprise AI assistants, model APIs, retrieval-augmented generation and evaluation frameworks.
  • Proven experience building and operating production platforms in platform engineering, cloud engineering, DevOps or site reliability, with a developer-experience focus.
  • Strong technical skills in Microsoft Azure or equivalent cloud, containers and Kubernetes, infrastructure as code and CI/CD.
  • Experience building developer-facing products - SDKs, APIs, templates, golden paths - and measuring their adoption and impact.
  • Experience integrating enterprise systems through APIs and connectors with identity, secrets management and role-based access control built in.
  • Proficiency in Python and at least one other production language.
  • Experience managing cloud cost, capacity and vendor relationships, including FinOps principles.

We also want to put it out there that we actively encourage applications from a diverse demographic and we are passionate about your culture and value alignment.
