We love Go, HTTP, gRPC and containers!
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.
Our platform ingests tens of millions analytic events every day which are visualised in our BI tools and we make data-driven decisions daily.
If you're looking to work on complicated technical challenges at scale then this role is for you. Ideally you have several years experience using Go (or another language like Python, Ruby, PHP, NodeJS) in production. You'll be comfortable with Docker, and have some familiarity with modern observability tools such as Prometheus, Alert Manager, Grafana and X-Ray/Tempo/Jaeger.
