Job Description

About the Role

First Street is the standard for Climate Risk Financial Modeling. We use transparent and peer-reviewed methodologies to calculate the past, present, and future climate risk for every property in the world. We started working with the world's leading climate scientists to create groundbreaking, climate-adjusted, property specific models over 8 years ago and haven't stopped. Our mission is to connect climate and financial risk. We create physics-based, deterministic models of flooding, wildfire and hurricanes, and advanced statistical models of extreme heat, air quality, drought, hail, severe convective storms, winter storms, and more. All of this data is used to create property-level financial risk metrics and macroeconomic variables to quantify the impacts of climate, property by property. Our customers include government agencies, major banks, institutional investors, and millions of everyday users on various real estate platforms. We believe that with the right data, we can identify problems, avoid bad investments, and implement solutions. We have invested heavily in science, data, people, and products to accelerate our impact.
