About this job
Are you ready to do meaningful internship work on technology that is changing how AI systems are built? This team is Lightmatter's Central Data Platform, the Snowflake foundation that engineering, product, and analytics teams across the company build on. This summer you will help bring AI into that platform: Cortex Agents that answer questions over trusted data, semantic views that give those agents a shared definition of business metrics, and AI features built into applications already running in Snowflake. The components you build will be documented and reused by engineering teams across Lightmatter.
Responsibilities
- Build and evaluate Cortex Agents that combine Cortex Analyst (structured data) and Cortex Search (documents) to answer engineering and analytics questions in natural language.
- Design semantic views over core data products, defining metrics, dimensions, and relationships so agents and BI tools return consistent answers.
- Integrate AI into applications already deployed in Snowflake, such as Streamlit apps, using Cortex AI SQL functions and agents exposed through Snowflake's managed MCP server.
- Set up the AI gateway, observability, and orchestration layer: governed model access, evaluations and tracing, cost and usage monitoring, and scheduled workflows.
- Package the work as reusable, documented platform components (templates, Cortex Code skills, runbooks) and demo them to engineering teams at the end of the internship.
Requirements
- Currently enrolled in a Master's program in Computer Science, Data Science, or a related field
- Interest in data engineering, data platforms, and applied AI
- Demonstrated interest in building and improving AI-based tools, shown through personal projects, coursework, research, or open-source contributions
Preferred Qualifications
- Coursework, projects, or internship experience with SQL, Python and cloud data warehouses (Snowflake preferred).

Our internship hourly rates are a standard pay determined based on the position and your location, year in school, degree, and experience.
