• Develop internal tools, CLI/MCP interfaces, and service APIs that help agents and users query, import, and maintain knowledge safely and efficiently.
• Collaborate with product managers and engineers to turn real business scenarios into reusable Knowledge Bank capabilities.

Our internship program offers students hands-on experience, industry exposure, and opportunities to apply their knowledge to real-world challenges while building a strong foundation for personal and professional growth.
