Transloadit is a service in file uploading &amp; encoding. We're bootstrapped and hailing from Berlin. We're currently looking for a full stack developer <a href="https://transloadit.com/jobs/full-stack-developer/" >.
We're heavy on node, CoffeeScript, Go, bash. We were the first to run node.js in production and had to invent many wheels because of it. 
Much of that has been written in the public domain, so you'll be working (REMOTE) on open source a lot too.
