We've lots of interesting things to work on, including:
* Spliting our monolithic rails app in to discrete services
* Redesigning our data storage to handle the next 100x growth
* Improving fault tolerance within the application until there are no single points of failure
* Shrinking the time taken from a push to master until production deployment to less than 10 minutes
* Building tools and processes to help us detect and respond to operational issues quicker
* Increasing visibility in to app performance by working on our graphite or logstash infrastructure
* Designing and rolling out a websocket infrastructure capable of handling hundreds of thousands of concurrent connections
