Economist Intern- Summer 2025

Program Dates: June 2 - August 8, 2025

*This is a Boston based opportunity with a 3 day in office expectation*

Who We Are: 

Wayfair is looking for economists to tackle difficult empirical problems. Causal inference, empirical IO, and time series modeling, often coupled with principled experimentation, are essential to driving the decision making algorithms that power our core business. We build our systems from the ground up with economic fundamentals in mind. 

You will be part of the Pricing, Profitability, Demand Forecasting team, consisting of ~20 full time economists and ML scientists. We are a close knit science team, with a lively economist/science community with quarterly hack-a-ton, weekly reading groups in causal inference/forecasting/ML. We work in close collaboration with engineering, data science, and product teams as well as with commercial teams and opportunity to influence company strategies. The team builds key science components for many of our pricing, market design, finance, and operations systems. Our Economist role has 3 different skill sets: 

1. Reduced Form Causal Analysis
2. Empirical Industrial Organization
3. Time Series/Forecasting

This year, we are hiring interns specifically within our Reduced Form Causal Analysis and Empirical IO functions. We will ask you to specify the skill set you rate yourself highest on our application, and will focus our interviews accordingly. 

You will have the opportunity to play a critical role in a growing company while also operating with a high level of executive visibility. The team is focused on creating strategic solutions that steer customer and supplier behavior and influence key decision making. Our employees enjoy an environment of strong ownership and quick feedback from building, experimenting and iterating on high-impact work.
