Our culture

We have hubs in the Bay Area, NYC, Austin, Toronto, and São Paulo. However, we maintain a remote-first work culture. #WorkFromAnywhere

We hire talented, self-motivated individuals with extreme ownership and high growth orientation.

We value performance and not hours worked. We believe you shouldn't have to miss your family dinner, your kid's school play, friends get-together, or doctor's appointments for the sake of adhering to an arbitrary work schedule.

Strong hands-on experience with Python/R and SQL is essential, with Spark being a nice to have
