Backend Software Engineer for Core Platform Services

Postmates is transforming the way local goods move around a city by enabling anyone to get any product delivered in under an hour. Available for iPhone, Android and on the web, the on-demand logistics service connects customers with local couriers, who purchase and deliver goods from any restaurant or store in a city, 24/7.

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.

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.
