About the role
Key responsibilities & impact- Developing MCP-like tools that expose network device APIs and CLI commands with clear descriptions, structured inputs/outputs, validation logic, and error handling
- Managing tool metadata and supporting semantic search over available tools using a vector database
- Creating golden user queries, expected answers, and query variations for specific tools, intents, and network-operation scenarios
- Building automated tests to verify correct tool selection, tool parameterization, output structure, and end-to-end agent responses
- Designing evaluation workflows combining deterministic checks, human review, and LLM-as-a-judge techniques, for example using DeepEval or custom evaluation prompts
- Refining prompts, tool descriptions, schemas, and agent workflows while monitoring regressions when new tools or changes are introduced
- Developing production-quality Python code and tests using frameworks such as LangChain and LangGraph
- Collaborating with software engineers, network domain experts, and DevOps teams to deliver reliable, testable, and maintainable agentic workflows
Requirements
What you’ll need- AI and development expertise: Hands-on experience with LLM-driven workflows, agentic frameworks such as LangChain and LangGraph, and tool-calling patterns

- Search, RAG, and prompting: Experience with semantic search, vector databases, RAG patterns, prompt engineering, and structured LLM outputs
- Testing and evaluation: Experience creating golden queries, automated tests, regression checks, and chatbot/agent response evaluations, including LLM-as-a-judge approaches
- Python engineering: Proven experience developing production-quality Python code, including automated tests and maintainable integration logic
- Networking expertise: CCNA certificate or equivalent knowledge. Understanding of networking platforms, device commands, and troubleshooting
- English (B2 level at minimum, but preferably C1 or C2)
