I see. Well, atom.io interests me a lot, since I know a little bit of JavaScript and contributed to a relatively medium-sized game framework (melonJS). I will try just starting with small bugs and work my way up the ladder.

I was asked to meet the CEO tomorrow to sign an IP assignment agreement, and I have not signed anything yet, so I assume I am ok legally speaking.

By the way, the CEOs of these small start-ups were 100% honest with the pay considerations and I feel kind of bad now that I have to go and say that I will not be joining their start-up.
