My employer is currently looking for a senior dev doing really complex stuff in and on C++ code. This is in Ottawa (Canada) and not remote.
The product is a niche dev tool. It's not a compiler, but it's that kind of problem space.
If you're interested, please DM me and I'll provide more details. I'm being vague because I don't want to link my work and personal online presences.
FWIW, I genuinely like my co-workers and enjoy this kind of work.
Boosts are okay.
