San Francisco, CA, US

WHO WE ARE

Postmates enables anyone to have just about anything on-demand. We pioneered the on-demand space and currently serve 80% of US households 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. We’re building a movement to make Postmates a verb: Postmate it.

WHAT WE DO

At Postmates X, we are reimagining how things move in cities. Serve, our personable sidewalk delivery robot, is our vision for the future of delivery. It’s designed to take deliveries away from congested streets and onto underutilized alleys and sidewalks, to save energy, reduce emissions, reduce traffic, and make deliveries faster and cheaper. Why move two-pound burritos with two-ton cars? 

 Serve has been years in the making and has already done thousands of customer deliveries. 

 

Who are we?

We are tech industry veterans in software, hardware, and design who are pooling our individual talents together to build a legacy. Our team is inclusive, agile, and driven by a common purpose. We are solving real-world problems with machine learning, computer vision, and robotics, with a mindful eye towards the end-to-end user experience. By joining our team, you will help create the first robotic helpers entering our cities: moving alongside us and running our errands!
