I've been hiring Rails devs for the past year and here are my thoughts on the subject. If you're a classical Rails dev (no frontend experience with Ember, Angular, or Backbone) then you should have significant experience on the backend in terms of building APIs, provisioning and configuring cloud servers, and scaling databases. Ideally, you've done this work at a successful shop that has reached meaningful scale to where you've learned where the framework works and where it falls down. If you lack those skills, then you better hop on the tech treadmill and get in shape on the client side. Learn a frontend JS framework or get some native mobile dev experience so you can remain full stack. Just being able to just sling Rails Views around with jQuery simply doesn't cut it any more.
