Your Role
This role focuses on designing and building the AI brain for autonomous network operations. The AI / LLM Engineer will develop LLM-based agents, RAG systems, multi-agent workflows, semantic search, graph-enhanced reasoning, predictive analytics, KPI models, fault correlation models, and closed-loop decision support capabilities.
Key Responsibilities
- Design and develop LLM-based and agentic AI solutions for autonomous network operations.
- Build RAG frameworks using network documentation, alarms, topology, inventory, KPIs, trouble tickets, procedures, configuration data, and operational knowledge.
- Develop multi-agent workflows using LangChain, LangGraph, MCP, or similar frameworks.
- Implement vector search, semantic retrieval, graph-enhanced retrieval, and hybrid search patterns.
- Develop AI agents for fault diagnosis, root-cause analysis, KPI analysis, configuration recommendation, incident summarisation, and operational decision support.
- Build token-efficient prompting, context optimisation, caching, and response generation techniques.
- Integrate LLM solutions with OSS, AIOps, inventory, graph databases, vector databases, data pipelines, and automation platforms.
- Develop fault correlation, KPI modelling, predictive analytics, and closed-loop trigger logic.
- Implement safe AI workflows with human-in-the-loop approval, confidence scoring, explainability, and auditability.
- Optimise AI models and agent workflows for latency, cost, accuracy, and reliability.
- Support model evaluation, prompt evaluation, hallucination reduction, retrieval quality improvement, and grounding validation.
- Work with cybersecurity teams to implement LLM security, prompt injection protection, data leakage prevention, and access controls.
- Deploy AI services using Kubernetes, Docker, APIs, and cloud-native patterns.
Your Profile
- Experience in AI/ML engineering, data engineering, software engineering, or applied machine learning.
- Hands-on experience with LLMs, RAG, semantic search, or agentic AI systems.
- Strong Python programming skills.
- Experience with ML fundamentals, deep learning concepts, embeddings, transformers, and LLM architectures.
- Experience using LangChain, LangGraph, LlamaIndex, AutoGen, MCP, or similar AI frameworks.
- Experience with vector databases such as Pinecone, Weaviate, Milvus, Qdrant, ChromaDB, or equivalent.
- Experience with graph databases, knowledge graphs, or Graph APIs.
- Experience building data pipelines and integrating structured and unstructured data sources.
- Understanding of AIOps, fault correlation, KPI modelling, predictive analytics, or telecom network operations.
- Experience deploying AI services using Kubernetes, Docker, APIs, and cloud-native environments.
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.
