Job Description


Postmates enables anyone to have just about anything on-demand. We pioneered the on-demand space and currently serve 3500+ cities with a fleet of more than 350,000 Postmates and the largest network of merchants in the US. We’re changing the landscape of commerce by making cities our warehouses, providing the delivery infrastructure, and connecting our customers to any product, anywhere, anytime. Postmates isn’t just an app, it’s a way of life and a part of pop culture. We are the O.G. of on-demand and we’ve given people a new superpower — the ability to Postmate anything from anywhere.
