About the role

This is a high-impact, high-expectations role designed as a direct pathway to a full-time position. You will work closely with a senior technical lead to build an explainability and observability layer for our LLM-driven automation systems, with a focus on sophisticated internal tooling that monitors data integrity and model behavior. Beyond internal systems supporting the reinforcement learning lifecycle, you will also contribute to customer-facing analytics that clearly communicate insights derived from the internal tools you helped build.

This is not a training internship. We expect you to ramp quickly, take ownership, and deliver production-ready work with minimal hand-holding.

What you’ll work on

• Building interactive explainability tooling for LLM-based systems using React and D3.js

• Developing and extending backend APIs in Python to support analytics and tooling

• Writing efficient SQL and contributing to data workflows on Databricks

• Translating model behavior, feedback-loop data, and quality signals into clear, actionable visualizations

• Partnering closely with your mentor to design, implement, and ship features end-to-end

• Iterating fast based on real stakeholder feedback from internal and customer-facing teams
  

Tech stack

• Frontend: React, JavaScript (TypeScript a plus), D3.js

• Backend: Python (FastAPI-style services)

• Data: SQL, Databricks (PySpark a plus)

• Platform: AWS
  

What we’re looking for

• Strong hands-on experience with React and modern JavaScript

• Comfort building data visualizations and interactive analytical tools (D3 strongly preferred)

• Solid Python + SQL skills and the ability to work across the full data stack

• Strong product and design intuition - you care deeply about clarity and explainability

• Extremely high agency: you move fast, unblock yourself, and deliver

• Kind, curious, creative, and respectful - you approach problems and people with empathy, intellectual humility, and a genuine desire to understand, while bringing original ideas and treating collaborators with care.
  

Path to full-time

This role is explicitly designed as a pipeline to a full-time Applied Data Scientist position. Strong performance, consistent delivery, and clear ownership over key parts of the system will be the basis for conversion. We are also open to non-students who are open to a contract position.
