Senior AI Engineer (Python, LLM, RAG) - £850 per day (Inside IR35) - Remote (Some occasional office visits - London)

Are you an experienced software engineer who knows how to move generative AI beyond novelty demos and turn it into robust, production-grade enterprise software?

We are seeking a Senior AI Engineer to partner directly with key business leaders and build high-impact, production-ready AI solutions across our global organisation. Sitting at the intersection of business strategy and core engineering, you will lead discovery, architect end-to-end architectures, write production code, and take total ownership of systems in live environments.

The Role

• Build & Deploy: Architect, ship, and operate production generative AI systems—including enterprise copilots, intelligent search experiences, and complex agentic workflows.
• Advanced RAG Pipelines: Design end-to-end retrieval-augmented generation architectures, managing chunking strategies, embeddings, vector stores, and prompt design.
• Agentic Workflows: Build autonomous agents that plan and execute multi-step tasks within auditable boundaries and strict guardrails.
• Eval-Driven Development: Establish rigorous testing frameworks up front to evaluate correctness, manage latency, eliminate hallucinations, and prevent regressions.
• Enterprise Integration: Integrate modern AI tooling with existing data pipelines, APIs, and MLOps platforms while embedding strict security, privacy, and compliance controls (IAM, encryption, audit logging).
• Operational Excellence: Apply sound FinOps principles to manage inference spend and token usage effectively as solutions scale.
