Senior AI Engineer, Knowledge Graph & GenAI

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.
• Design scalable APIs and services in Python (FastAPI) and Node.js / TypeScript, backed by PostgreSQL, Neo4j, Redis and vector stores.
• Deploy and operate workloads on AWS and GCP using serverless, containerised and event-driven patterns.
Security & Compliance • Enforce HIPAA-grade controls: encryption with KMS, RBAC, JWT/OAuth authentication, audit logging and per-tenant key management.
• Translate regulatory and client compliance requirements into concrete architecture and engineering standards.
Leadership & Delivery (Nice to Have) • Lead and mentor a team of 2 to 4 engineers through architecture reviews, code reviews, sprint planning and delivery milestones.
• Act as the primary technical point of contact for clients: gather requirements, propose solutions, report progress and manage expectations.
• Raise the bar on code quality, documentation, testing and engineering practices across the team.
REQUIRED SKILLS & EXPERIENCE • 5+ years of software engineering experience with significant hands-on experience in AI/ML or GenAI.
• Strong Python skills and experience with FastAPI.
• Hands-on experience building RAG, LLM and AI agent applications.
• Experience with LangChain, LangGraph, LlamaIndex or equivalent.
• Strong understanding of embeddings, vector search and semantic retrieval.
• Experience with Qdrant, Pinecone, ChromaDB, pgvector or similar.
• Experience with Neo4j and Cypher is highly desirable.
• Strong PostgreSQL / SQL skills and experience with Redis.
• Experience with Node.js / TypeScript; Next.js / React is a plus.
• Experience with AWS and/or GCP, Docker and CI/CD.
• Strong understanding of APIs, asynchronous processing, testing and debugging.
• Good communication skills and ability to independently own technical problems.
GOOD TO HAVE • Experience with LLM or vision model fine-tuning workflows, GPU-backed training and model registries.
• Computer vision with PyTorch / TensorFlow, OpenCV, YOLO or U-Net.
• Payment and real-time integrations such as Stripe, Razorpay, Socket.io or Pusher.
• Comfort with AI-assisted development tools such as Cursor or Claude Code.
QUALIFICATIONS • Bachelor’s degree in Engineering (IT / Computer Science) or equivalent practical experience.
