ROLE OVERVIEW
We are looking for a hands-on Senior AI Engineer to build production-grade AI systems using Generative AI, RAG, GraphRAG , knowledge graphs, vector search, LLM orchestration and computer vision. You will work on real-world AI products across healthcare, enterprise software and data platforms, taking solutions from experimentation to production.
The ideal candidate has strong software engineering fundamentals, hands-on experience with LLMs and RAG systems, and the ability to work across AI, backend, data and cloud technologies.
KEY RESPONSIBILITIES
AI & GenAI Engineering
Build production-grade RAG and GraphRAG systems combining LLMs, vector search, knowledge graphs and structured data.
Develop LLM workflows using LangChain, LangGraph, LlamaIndex or equivalent frameworks.
Build AI agents, tool-calling workflows and stateful AI pipelines.
Implement embeddings, semantic search, chunking, reranking and hybrid retrieval.
Develop text-to-SQL, text-to-Cypher and natural-language query systems.
Build LLM evaluation pipelines and optimise accuracy, latency and cost.
Work with LLM APIs and batch processing using models such as OpenAI, Anthropic and other foundation models.
Knowledge Graphs & Data
Design and work with Neo4j knowledge graphs, including graph modelling and Cypher queries.
Build semantic enrichment pipelines including entity extraction, entity linking and relationship extraction.
Develop data pipelines using Apache Airflow or equivalent orchestration tools.
Work with PostgreSQL, Redis, Qdrant and other vector databases.
Process and index large-scale enterprise datasets for AI applications
Platform & Data Engineering
Architect multi-tenant SaaS platforms with strong data isolation across database, storage, API and orchestration layers.
Build and maintain data pipelines with Apache Airflow, including ETL, DAG orchestration, data quality checks and real-time synchronisation.
