Work closely with application, data, platform, security and infrastructure teams to deliver solutions. Take a practical, delivery-focused approach, with no over-engineering and no hype. Required Skills & Experience Minimum 6 years of software engineering experience, with proven delivery of GenAI applications into production (not only prototypes or demos). Strong hands-on experience with LangGraph, LangChain or similar frameworks, including RAG, agentic workflows, tool calling and prompt orchestration.
