Software Engineer: Backend (Payments)

Postmates, San Francisco

Delivery from all your favorites places on-demand

Passionate about building massively scalable systems? Want to work with a top class team of engineers ranging from new graduates to seasoned managers and architects? Want to make a billion-dollar impact? If so, here is an opportunity tailored for you.

Who are we?

Postmates is disrupting local commerce by providing a marketplace where consumers can purchase goods from any local restaurant or store and local couriers deliver the goods to their home in minutes. Postmates has unlocked on-demand local shopping — providing consumers the convenience of super fast delivery for the largest selection of goods (anything in the whole city!); the benefit and scale of e-commerce for local merchants; and more flexible work for couriers.

This is a tall order, and Postmates relies heavily on our engineering applications and systems to realize this vision. Even though we are already a billion dollar business with millions of customers in 300+ US cities trusting us with more than 2M orders every month, we have only just started our technical journey to build our technology stack in a way that can keep up with our rapid growth.

What does this team do?

Our payments platform makes it easy for developers within our organization to integrate with external payment processors, providing reliable, PCI compliant payment experiences while being cost effective across a number of downstream processors.  In addition to payments processing, payments engineers work closely with our fraud prevention and data science teams to ensure that profit margins are protected from theft and accurately reported. 

What will you do?

As an experienced software engineer, you will be responsible for all aspects of product development. This includes design & coding of new architecture, services, and features, but also drive improvements to day-to-day operations & observability of existing production services. Helping to select the right technologies and prioritize engineering tasks.  Finally, you’ll have lots of opportunities to help us build & grow the team via mentoring, hiring & training.
