howareyou.com – Shoreditch, London. Front-end developer, onsite.
We're hiring for a senior front-end developer (JavaScript, Angular.js, Node.js – for tooling – and LESS, to name a few technologies), someone who is not reliant on frameworks, who understands performance implications of a given solution (especially on mobile) and who is comfortable with terminal and scripting languages.
We are behind howareyou.com <a href="https://howareyou.com/" >, an award winning online health record completely free to NHS professionals and patients.
We are committed to building the best clinical API <a href="https://api.howareyou.com/" >, highly available and secure. Our API is a collection of services distributed across multiple infrastructures (including AWS).
Our approach:
   - 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 (including regular speakers at Ruby Manor and other leading conferences) from Google Campus, less than 5 minutes walking distance from Old Street station.
For the best contractors, we are willing to pay £450 per day. All candidates are encouraged to get in touch with us on REDACTED_EMAIL
