Kira Talent (<a href="https://www.kiratalent.com" >) - Toronto, Canada
At Kira Talent, we help organizations find exception talent through video.
A bit about us:
  - we’re a small team (you’d be #15), based in the heart of downtown Toronto; 
    check us out at www.kiratalent.com/about/

  - we’re had paying clients since day 1 of the company, and are well funded

  - we’re hiring both  mobile and backend developers

  - we believe that even enterprise software can be beautiful, 
    and pride ourselves on our design 

  - every single one of our developers have committed code within their
    first day at work (some within their first hour), and because
    we love continuous deployment, so we're constantly pushing to
    production and seeing the impact of our work

Here’s some stuff we’ve been working on lately:
  - building infrastructure to allow us to scale our video recording 
    and streaming; imagine thousands of applicants from countries 
    all around the world submitting video interviews right before a deadline

  - designing and creating our mobile suite for both job candidates and
    employers alike 

  - presenting analytics data captured in our product to the end user,
    and our team internally

Our toolkit involves Python (Django), JavaScript (jQuery, AngularJS), MySQL (and some MongoDB), Celery, RabbitMQ, Wowza Media Server. We use AWS for hosting, CircleCI for continuous integration and GitHub for everything else (i.e. code reviews, issue tracking).
If this sounds fun, let’s chat! My name is Konrad, I'm the co-founder/CTO, and you can send me a note at REDACTED_EMAIL. :)
