Senior Engineering Manager, Site Reliability

Postmates, San Francisco, Santa Monica, or Bellevue

Delivery from all your favorites places on-demand


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. We’re building a movement to make Postmates a verb: Postmate it.


Postmates relies heavily on our engineering team to realize this vision. Building a software platform that is reliable, scales, and stays agile under demanding product needs is a serious technical challenge. Postmates is a three-part balancing act connecting customers, merchants, and couriers in real-time. If any piece is out of whack, the whole system suffers. Working with the Postmates engineering team offers an opportunity with explosive growth, cutting-edge technology, a highly visible charter, and a cool user-focused product vision.
