Software Engineer: Backend (Merchant Team)

Postmates, San Francisco

Delivery from all your favorites places on-demand

Postmates runs the largest on-demand delivery platform in the country; we grow 5-10% week-over-week, fulfill over a million deliveries each month, and recently surpassed $1 billion dollars in gross merchandise sales. We aren’t just another ad platform or mobile app for serving static user generated content – we have real customers, merchants, and couriers using the platform to buy, sell and deliver goods in under an hour.

As a backend software engineer on the merchant team, you’ll be at the center of our marketplace, scaling live ordering channels and improving the efficiency with which we can bring new businesses on to the platform. A key competitive advantage is buyers can find almost anything they want on Postmates, because we make it easy for businesses of all sizes to work with us - whether using the web, our custom Android-based tablet, APIs, or even the phone. We need engineers who aren’t afraid to attack deep technical challenges as well as have a meaningful role in product development.

Our backend infrastructure is primarily Python/Django and Elixir with Postgres databases. We like to use the full set of tools and services available to us from AWS to build out new functionality in a service-oriented environment. We value both generalist and specialized engineers looking to expand their capabilities. You will be developing new services and deploying them within an immutable infrastructure. We want people that want to get their hands dirty understanding our complex three-sided marketplace and improve our core technology.
