Software Engineer: Backend (Core Platform Services)

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?

The Core Platform Services team is the backbone of Postmates' microservice architecture. We build and own a portfolio of Postmates’ platform services that are leveraged by mobile and web applications. Our order management service handles the data and business logic for millions of customer orders per month. We've built an authentication service which provides OAuth tokens so any client can speak to any Postmates service with a trusted user identity. As part of the team, you should be up for the challenge to take on new domains and be ready to build those into highly available services. Our backend technology stack is based on Elixir, Go, Python and Postgres.  Additionally, as a team we help choose the architecture, tools and design patterns that will scale Postmates from millions of users to hundreds of millions.

What will you do?

You will be responsible for all aspects for product development. This not only includes design & coding of new services and algorithms, but also helping define the strategic direction for such systems. We are building the technology from ground up, so we are not tied to any one technology. Helping select the right technologies is part of the role. So is working with multiple internal and external distributed services. Finally, this being a new team, you’ll have lots of opportunities to help us build & grow the team via mentoring, hiring & training.
