Repl.it (YC W18) | Frontend, mobile, backend, Support, Bizdev | SF or REMOTE | https://repl.it/jobs

Repl.it is the first massively open collaborative computing platform where anyone, even without even needing an account, can hop on and in seconds start coding, building, and hosting applications and websites.

Apply if you like working on challenging problems, because running a service like this is hard to scale, make sure it's secure and easy to use. Also, supporting the number of languages we do (https://repl.it/languages) is a hard tooling problem -- we have to build generic protocols for all IDE actions like executing, debugging, authoring, running tests, writing files, etc. Finally, it's an incredibly challenging frontend/design problem to build a fast collaborative in-browser IDE that's both powerful and simple.

It's a great time to be joining us, we're still 12 full-time people, we reach millions of coders a month, and we're backed by YC and a16z.
