Come and join our backend team and design, build and support APIs that are requested tens of millions of times per day as well as internal tools that keep our community safe and our business efficient.

We run a modern containerised stack in AWS using a mixture of database technologies (MySQL, DynamoDB, Redis, Redshift, Elasticsearch) to serve different workloads. Our architecture is event-driven and we're bringing increasingly more machine learning into the hotpath.
