Mozilla allows almost every job to be remote and Firefox is written in C/C++. I'm sure there must be other companies :)
I'd be a little concerned of the culture at Mozilla though.
Mozilla's current board considers pandering to external forces more important than the old ways - merit, the hacker ethic, professionalism.
I can confirm they have vacant positions, I talked to a few who found work elsewhere after coup removed Eich.
It's sad when a company loses its way, but thankfully chromium is much faster.
Interesting. Do you have a source on that? Not denying what you're saying or anything.
