I'm an Israeli/American founder of a software company. I'm very happy to hear your story. I hope you inspire many other Gazans. I'd hire Palestinians remotely too.I recall my first airplane trip. Very exciting times for you. I wish you lots of success and happiness in your journey. You've chosen a fantastic path that will God-willing reward you and your family. May there be peace between our people soon!
I wouldn't really say that...the newer generation knows much less Hebrew than the older ones that used to work in Israel, and in Gaza probably even more so than the West Bank. But all the hitech work is in English so it is not really a problem in this sense.
I know Mellanox has some:

But the bigger issue is the willingness to hire Palestinians(and legal issues as well), and afterwards to work with them as well, as there is animosity on both sides, especially with people who currently live in Israel/Palestine as opposed to ones that live in Europe.
