Mondido Payments (Full time Stockholm, Sweden). 
<a href="https://www.mondido.com/en" >
We’re a hungry team from Sweden, Finland and United States that are building the next generation payment platform.
Today we work with AWS, Heroku Rails, JS/HTML  (and probably node soon) and need more curious people to go faster.
If you think responsive, high available and performant applications are fun and challenging then you should send us a ping!
We’re looking for a backend Rails developer, and a frontend html/js developer that either are great with design or with js.
Relocation could be possible if you are the right person!
