• Proficiency in Python and experience with common data science libraries (e.g., pandas, scikit learn, PyTorch, or similar).
• Proficiency in SQL and relational databases; exposure to big data or cloud platforms is a plus.
• Familiarity with Generative AI concepts (LLMs, prompt engineering, embeddings, RAG) through coursework or projects.

Preferred Qualifications:

• Experience with version control (e.g., Git) and basic software engineering best practices.
• Strong analytical and problem solving skills with attention to detail.
• Good communication skills and the ability to work effectively in cross functional teams.
• Eagerness to learn, take feedback, and grow in a collaborative environment.

When you join our team:
