• Expertise in retrieval-augmented generation (RAG) workflows and document retrieval techniques to enhance content relevance
• Hands‑on experience working with large‑scale language models, such as GPT/Claude/Gemini/Qwen, along with a solid understanding of prompt engineering, embedding techniques
• Familiarity with the Model Context Protocol (MCP) for connecting LLM agents to external tools and data sources
• Experience in rapid prototyping of AI‑driven capabilities using LLMs, embeddings, and structured/unstructured data sources
• Experience with code generation and AI‑assisted development tools (Claude Code, GitHub Copilot, Cursor, Codex)
• Strong written and spoken English communication skills (B2)

Nice to have:

• Experience with Python frameworks such as Django, Flask, or FastAPI
• Proficiency in SQL for working with structured databases, querying data, and optimizing database performance
• Familiarity with platforms Dataiku, Snowflake, Tableau, Streamlit, Artifactory, dbt
• Hands‑on experience with NLP deep learning frameworks such as PyTorch, TensorFlow, and Transformers
• Familiarity with graph RAG approaches (Microsoft GraphRAG, LightRAG, or Neo4j-based solutions)
• Understanding AI cost optimization: model routing, caching strategies (semantic caching), prompt compression, and token management

We offer:

• Competitive compensation
• Remote or office work
• A team with excellent tech expertise
