We are behind howareyou.com, an online personal health record completely free to all NHS patients.
We are committed to building the best clinical API (<a href="https://api.howareyou.com/" >https://api.howareyou.com/</a>), highly available and secure. Our API is a collection of services distributed across multiple infrastructures (including AWS).
The right candidate will be interested in:
  * RESTful APIs - including the hypermedia component
  * non-web Ruby services - we’re big on EBI (Entity-Boundary-Interactor)
  * non-Rails apps - we are slowly phasing out Rails
  * client-side apps - our newest apps are all Angular.js talking to APIs
  * Service Oriented Architecture
  * hybrid infrastructure
  * Redis and Riak - masterless clusters is where we’re heading

You will be working alongside the best in their field from Google Campus, less than 5 minutes walking distance from Old Street station.
