Senior Python AI Engineer
Summary
Build production-grade agentic AI systems in Python, designing workflows with LangGraph, RAG pipelines, and robust context management for a regulated environment.
Contract: 6-Month Rolling Contract (Strong Long-Term Potential)
Location: Dublin, Ireland (Hybrid - 3 days onsite)
Stelfox is partnering with a leading organisation in Dublin to hire a Senior Python AI Engineer to design and deliver production-grade agentic systems in a highly regulated, mission-critical environment.
This is a hands-on engineering role with real ownership across architecture, scalability, and end-to-end delivery.
What you'll be doing
- Design, build, and operate agentic AI systems using Python
- Develop agent workflows using LangGraph or similar orchestration frameworks
- Implement robust context management strategies across complex, multi-step executions
- Build and optimise RAG pipelines across structured and unstructured data sources
- Integrate AI solutions with internal platforms via REST APIs and event-driven systems
- Define and implement orchestration patterns (sync, async, human-in-the-loop)
What we're looking for
- 5+ years' experience in software engineering with strong Python expertise
- Hands-on experience with LangGraph or similar agentic frameworks
- Strong understanding of context management and MCP-style protocols
- Proven experience with RAG architectures, embeddings, and retrieval strategies
- Solid grasp of distributed workflows (state, retries, idempotency)
- Strong systems design skills with a focus on scalability and resilience
Nice to have
- Experience with NoSQL, relational databases, and vector stores
- Exposure to event-driven architectures (pub/sub, queues)
