• Experience working with at least one graph database (preferably Neo4j) for data modeling and basic queries.

• Good understanding of machine learning fundamentals (regression, classification, basic model evaluation).
• Exposure to using or integrating LLMs (OpenAI, HuggingFace, or similar) with data workflows.
• Basic knowledge of retrieval-augmented generation (RAG) concepts.
• Familiarity with Python data libraries (pandas, scikit-learn, etc.).
• Ability to work with RESTful APIs.
• Familiarity with version control (Git) and writing simple unit tests.

Nice to Have

• Hands-on experience building or optimizing graph ML models (e.g., node classification, link prediction).
• Exposure to vector search or hybrid search techniques.
• Experience deploying Python code or ML models using Docker or basic cloud services (AWS, GCP, Azure).
• Experience working in a SaaS or multi-tenant application environment.
