Alright... so you’ve made it all the way down

You’re probably wondering: “yeh, it sounds great, but what the hell is Flatworld?”

In a nutshell: we help developers find fully remote roles!

What makes us amazing for developers is that instead of applying to jobs individually, you simply apply to our platform and we take care of matching you to a company and getting you hired.

That means we go out and show the companies you're the right fit for them.

We will also hold your hand through the paperwork and hiring process so all you have to do is complete our application, show up to some interviews, and lay back while we get you the job.

It really is that simple... so simple that if Linus was a remote dev looking for a job he'd be like:

“Flatworld is just incredible... I can’t even explain it”

* No, Linus didn’t say this. But he probably would...
