This hybrid role offers flexibility, with two days in the office and three days working remotely.
We are looking for two Senior Agentic AI Developers
To lead the design and implementation of advanced agentic AI systems that can independently reason, plan, and act. This role requires proven experience developing agent-based architectures in Python using LangGraph, as well as strong expertise in integrating LLMs, RAG pipelines, and knowledge graphs to create scalable, context-rich intelligent solutions.
What will you be doing?
- Design and develop agentic AI systems using LangGraph, Python, and related orchestration frameworks.
- Architect and implement multi-agent workflows encompassing reasoning, planning, memory, and tool usage.
- Build and optimise Retrieval‑Augmented Generation (RAG) solutions integrated with LLMs, vector databases, and knowledge graphs.
- Develop and maintain knowledge graph pipelines to support context retrieval, semantic search, and reasoning.
- Integrate external APIs, data sources, and tools into agentic frameworks to extend agent functionality.
- Collaborate with product, data, and research teams to translate advanced AI concepts into production-ready solutions.
- Optimise deployed AI systems for performance, scalability, and reliability.
- Stay up to date with emerging research and advancements in LLM orchestration, agent frameworks, and AI reasoning.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Essential

- Demonstrated experience building and deploying agentic AI systems, including the development of robust RAG architectures (vector stores, document indexing, and retrieval pipelines).
- Hands-on expertise in LLM fine-tuning, prompt engineering, and effective context management.
- Practical knowledge of knowledge graphs and semantic data modeling, using technologies such as RDF, LPG, Neo4j, and SpannerGraph.
- Strong understanding of modern cloud platforms and MLOps tooling, including GCP and containerization with Docker.
- Excellent problem-solving skills, with the ability to translate research concepts into scalable, production-ready systems.
Desirable
- Experience with LangGraph and agent orchestration frameworks.
