Software Engineer: Backend (Risk)
Postmates, San Francisco
Delivery from all your favorites places on-demand
Postmates runs one of the largest marketplaces in the country, connecting consumers, merchants, and couriers in real-time. Building high powered intelligence atop our large-scale datasets is a serious challenge and we’re looking for candidates who are ready to dig in. Postmates isn’t just another ad platform or mobile app for delivering static content: We have real customers paying real money for a real service.
What does this team do?
Postmates enables hundreds of millions of dollars in local commerce every year. Our uniquely flexible platform facilitates the delivery of virtually anything from anywhere in over 60+ U.S. cities and we’re set to expand both our transaction volume as well as geographic footprint even further. Safeguarding this success takes work and that’s where the Postmates Risk Team comes in.
The Risk Team at Postmates builds systems to assess risk in real time and protect the platform from fraud. Our infrastructure aggregates, stores, and retrieves mission critical data. It supports statistical model creation and deployment. And it houses a real time graph database that provides a highly detailed picture of the entire Postmates ecosystem. Through the tools we build, the features we deploy, and the policies we put in place, we ensure the platform can continue to scale without succumbing to the threat of bad actors.

You’ll automate large scale interactions with our payment processors and 3rd party data providers.
