About the Team:

Gusto’s Data Science team leverages Gusto’s rich data to guide product direction and decision-making. We operate full-stack, conduct key driver analyses, run experiments and other methods for inference, and build metrics that help Gusto build the best product possible.

Communicate complex data concepts and findings to both technical and non-technical stakeholders, influencing strategy and product direction.

Here’s what we're looking for:

Someone who is currently pursuing a PhD or MS in a quantitative field such as Computer Science, Statistics, Mathematics, Economics, Data Science, or a related discipline, with an expected graduation date between December 2026 and June 2027.
Strong foundational knowledge in analysis, statistical modeling, and experimental design.
Proficiency in Python or R for statistical analysis and model building.
Experience with SQL for data querying and manipulation.
Experience with using AI to solve problems in a business or academic environment
Excellent communication and collaboration skills, with the ability to work in a cross-functional environment and explain complex concepts clearly.
A strong passion for using data to solve real-world problems and a track record of independent research or project work.

This is a hybrid role and will require you to be in the office at least twice a week in our San Francisco or Denver office. Relocation assistance will be provided during your internship.
