Agentic AI Engineer (LangChain LangGraph RAG LLM) London / WFH to £90k

Do you want to work on cutting edge AI technology being used in the real world?

You could be progressing your career as an Agentic AI Engineer at a successful and growing technology company that have recently received £40 million of series B funding.

The product enables business users to capture data via integrated mobile services utilising video analytics and speech recognition to analyse and categorise information within the workflows of large field workforces (surveyors, field engineers, health-and-safety, property sales, etc.); customers are typically large multinationals: utilities, telecoms, manufacturing and facilities management companies.

As an Agentic AI Engineer you’ll join a small cross functional team focussed on building the GenAI capabilities at the application layer, orchestrating decision making rather than training models. Typical use cases include video data extraction to analyse equipment details and observed health and safety issues to customer recommendations, for example triaging and dispatching personnel.

Responsibilities will encompass building and maintaining production LLM applications (prompt engineering, context design, guardrail development), development and optimisation of inference pipelines for accuracy, reliability and enterprise grade consistency and running evaluation workflows using automated tools (DeepEval, Langfuse) and human-in-the-loop review.

You’ll also support RAG and retrieval based features including vector databases and document processing pipelines. Collaborating with product and engineering team you’ll help to define use cases, set KPIs and ship AI features whilst providing subject matter expertise to both technical and non-technical stakeholders on GenAI capabilities and responsible adoption.
