Artificial Intelligence Engineer

AI Engineer - Security Clearance Required

We're looking for a capable, curious, and hands-on AI Engineer to help deliver intelligent solutions to our UK-based clients using our in-house agentic AI platform.

This role focuses on configuring, orchestrating, and integrating off-the-shelf LLMs, embeddings, vector databases, and toolchains - not model training or fine-tuning. You'll help build intelligent, explainable, and secure systems that solve real customer problems.

 

What You'll Be Doing

  • Design and deploy LLM-powered solutions on top of our core agentic AI platform
  • Build task-oriented AI workflows using pre-trained LLMs, embeddings, vector search, and tool integrations
  • Extend and adapt platform capabilities using Python
  • Translate business and user needs into orchestrated AI behaviours and workflows
  • Work closely with clients and delivery teams to shape solutions, from prototype to production
  • Ensure solutions are modular, secure, and reliable - while maintaining clarity and traceability in decision logic

 

What You Must Bring

  • UK-based and either hold SC clearance or be eligible and willing to go through clearance
  • 2+ years of experience in applied AI engineering, data engineering, or backend platform work
  • Strong experience in Python - capable of implementing algorithms and working with APIs, data structures, and logic flows
  • Good understanding of machine learning concepts, LLMs, tokenisation, and vector-based semantic search
  • Experience working with vector databases (e.g. Chroma, Weaviate, FAISS), and familiarity with relational or graph stores
  • Hands-on experience using frameworks like LangChain, Haystack, or custom orchestration layers
  • Ability to work independently and collaboratively across delivery and engineering teams

Nice to Have

  • Familiarity with ethical considerations, bias evaluation, and responsible AI deployment
  • Light DevOps or scripting experience to support deployment or debugging

 

Why This Role?

This isn't about training models - it's about making them useful. You'll help real users benefit from safe, practical AI without reinventing the wheel. Expect variety, challenge, and meaningful outcomes.

 

UK-based only. No sponsorship available. SC clearance (or eligibility) is required.
