SC Cleared AI Engineer (Advanced / GenAI / LLMs)
Contract | UK Remote | £550-£700/day
We're working with a client building advanced AI capabilities in secure, high-assurance environments. They are looking for highly technical AI engineers with strong academic backgrounds and proven experience building complex AI systems in production.
This is not a general ML role or a software engineering role with AI exposure. We are specifically looking for engineers who can design and build advanced AI solutions from first principles.
What you'll be doing:

• Building advanced AI systems including RAG, GraphRAG, and agent-based workflows
• Designing and deploying end-to-end AI pipelines
• Working on complex retrieval, reasoning, and optimisation problems
• Evaluating and improving model performance beyond baseline approaches
• Contributing to architecture decisions for scalable AI systems

What we're looking for:

• Active SC clearance (or recently lapsed, eligible for reactivation)
• Strong academic background (Computer Science, Mathematics, Engineering, AI or similar)
• Proven experience building production-grade AI systems
• Deep understanding of:
  • LLMs and their limitations
  • retrieval systems (RAG, embeddings, hybrid search)
  • agent frameworks or orchestration (LangGraph or similar)
• Strong Python skills and experience with modern AI tooling

Nice to have:

• Experience with GraphRAG or knowledge graph-based systems
• Experience with evaluation frameworks or model benchmarking
• Background in regulated environments (government, defence, finance)

This role is suited to engineers who can build and own complex AI systems, not just integrate existing tools.
If you're an experienced, technically strong AI engineer with SC clearance, we'd like to hear from you.
