I've done a little looking around for you and didn't turn up anything substantial, I imagine it's hard seeing as pilots have rough hours and I know the Shabbat doesn't allow jewish people to work, drive, and in some terms even cook, so if you were following your religion to the letter I'd guess your options as a CPL would be things like flight instruction where you could just not work on those days. Now that I think about it, Israir must have a fair few non-jewish pilots to be able to operate all week round and would probably be your best bet in terms of employment with an airline, I've tried looking for a careers page but didn't turn up anything, it seems they have no job openings at the moment, but it might be worth emailing them and asking them the T&C's of their pilot jobs as a jewish pilot and whether they are cool with it
