AI / Machine Learning Engineer – Agentic LLM Systems (Contract)
We’re working with a leading tech organisation building next-generation agentic AI systems – LLMs that can plan, reason, call tools, and write/execute code. We’re hiring a Machine Learning Engineer to help design, build, and scale these systems into production-grade, enterprise environments.
You will:
- Design and build tools, workflows, and infrastructure for agentic LLM systems
- Develop RAG pipelines, embeddings workflows, and retrieval systems for enterprise data
- Work with researchers and engineers to diagnose and fix failures in agent-generated code and workflows
- Build frameworks for tool-calling, multi-step planning, orchestration, and agent routing
- Integrate with LLM providers (OpenAI, Anthropic, Vertex AI, open-source models) and support multi-model usage
- Develop backend services and APIs to support AI-driven applications and workflows
- Build and run experiments to improve reliability, latency, cost, and success rates
- Contribute to evaluation frameworks, observability, and monitoring of LLM/agent performance
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.
What We’re Looking For:
- 4+ years’ experience in ML/AI engineering (LLMs, recommender systems, optimisation, or similar)
- Proven hands-on experience building LLM agents, RAG systems, or orchestrated AI workflows in production
- Strong Python (with PyTorch, TensorFlow, or similar frameworks)
- Experience with agent frameworks (LangChain, LangGraph, AutoGen, or similar)
- Solid understanding of APIs, backend services, and microservices architectures
- Experience working with cloud platforms (AWS, GCP, or Azure) and containerised systems (Docker, Kubernetes)
- Familiarity with event-driven or serverless architectures
- Experience with CI/CD pipelines, testing, and infrastructure as code
- Comfortable debugging complex, distributed AI/ML systems
- Experience running and analysing large-scale experiments and performance metrics (latency, accuracy, cost)
- Exposure to monitoring/observability tools for production systems
Get help with your application
Your very own career expert that helps elevate your application to the next level.
Nice to Have:
- Experience with multi-agent systems or distributed AI architectures
- Experience optimising LLM usage across multiple providers (cost/performance trade-offs)
- Familiarity with vector databases (Pinecone, Weaviate, OpenSearch, etc.)
- Experience integrating AI systems into enterprise platforms or business workflows
