MidSenior AI engineer with networking experience

Get to know us better

CodiLime is a software and network engineering industry expert and the first-choice service partner for top global networking hardware providers software providers and telecoms. We create proofs-of-concept help our clients build new products nurture existing ones and provide services in production environments. Our clients include both tech startups and big players in various industries and geographic locations (US Japan Israel Europe).

While no longer a startup - we have 250 people on board and have been operating since 2011 weve kept our people-oriented culture. Our values are simple:

• Act to deliver.

• Disrupt to grow.

• Team up to win.

The project and the team

Were building a software for modern platforms and operating systems supporting leading networking equipment manufacturers cloud-native solutions and infrastructure projects. AI/ML is increasingly at the heart of these initiativesnot as an add-on but as a core tool to address complex engineering and networking challenges. We are seeking an engineer with a strong software engineering background solid AI/ML expertise and experience in computer networks

Your role

As a part of the team will be responsible for:

• 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

Do we have a match

As a Mid/Senior AI engineer with networking experience you must meet the following criteria:

• AI and development expertise: Hands-on experience with LLM-driven workflows agentic frameworks such as LangChain and LangGraph and tool-calling patterns

• Agentic tool development: Experience designing structured tools with clear descriptions input/output schemas validation logic and integration with external APIs or command-based systems

• 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)

Beyond the criteria above we would appreciate the nice-to-haves:

• Experience with AI-assisted coding tools such as Codex GitHub Copilot Cursor or similar is a plus

• MCP and agent interoperability: Familiarity with Model Context Protocol MCP server design tool discovery tool permissions/scopes and emerging agent-to-agent communication patterns such as A2A

• Advanced agent architectures: Understanding of routing agents supervisor/planner patterns multi-agent workflows guardrails and architectures combining deterministic logic with LLM-based reasoning

• LLM evaluation tooling: Experience with frameworks and platforms such as DeepEval LangSmith OpenAI Evals TruLens BenchLLM or similar tools for evaluating LLM and agent workflows

• AI/ML for infrastructure data: Practical knowledge of classification clustering anomaly detection time-series analysis or statistical methods applied to telemetry syslog events alerts or operational data

• Production deployment and operations: Experience deploying AI/LLM-based solutions in production environments including Docker Kubernetes CI/CD monitoring MLOps or cloud/hybrid infrastructure

• Interactive analysis and visualization: Experience building dashboards notebooks or lightweight applications for analysis and validation using tools such as Jupyter Streamlit Plotly Altair matplotlib or similar
