Senior AI / RAG Engineer — Applied LLM & Retrieval

This is a deeply hands-on role for an experienced engineer who wants to spend their time building. A big part of the job is growing our fleet of AI sub-agents — designing current specialized agents and wiring them into complete, end-to-end multi-agent agentic workflows and architecture. You'll design, implement, and harden our RAG, agent, and LLM features end-to-end — the retrieval pipelines, the agent orchestration, the model-gateway routing and fallback logic, the AI automation pipelines, and the evaluations that keep quality high — all inside a GDPR-first, EU-only data boundary.



Your work ships to production and you own it through to it working reliably.

What you'll do
- Grow our fleet of AI sub-agents — design and build more and more specialized agents, and wire each into a complete multi-agent, agentic AI-driven workflow and architecture, from single-purpose agents up to orchestrated end-to-end flows.
- Build and improve RAG pipelines — chunking, embeddings, vector storage and retrieval, re-ranking, grounding and citation — over proprietary data such as work orders, rate cards, and uploaded documents.
- Build LLM features on cloud-hosted large language models — classification, extraction, summarisation, structured/JSON output, prioritisation, and multimodal (text + image) reasoning — from prototype through to production.
- Extend the internal Model Gateway — task/tier model routing, retries, fallback, cost estimation, and per-tenant usage limits.
- Build adversarial validation agents — AI agents that critique and stress-tes
