Our backend systems power the clients used by millions of customers every year to buy their groceries online. These systems must also support tight integration with the largest retailers in the US and Canada. Backend engineering at Instacart provides the opportunity to work on challenging scaling solutions while also designing the features that will define our industry. You'll have the opportunity to work with an Elasticsearch cluster serving millions of requests per day, a unique order lifecycle system that processes thousands of order per hour, and a recovery system capable of rebuilding the entire Instacart platform from scratch.
Our applications run on Ruby on Rails. We use Postgres, Elasticsearch, and Cassandra as our datastores. Memcached and Redis for caching. Kinesis for stream processing. Sidekiq for job processing. As we grow to serve more customers and deepen our relationships with our retail partners we are constantly given new opportunities to solve fascinating and rewarding challenges.
