Greater Boston area here. I've worked in C++ roles at two companies over the past three years and both times we were desperate for competent C++ developers. Similar trends for both companies: we had positions open for ~six months, interviewing many candidates, and being disappointed at their quality. We eventually filled the positions (about a half-dozen in total) but it was not easy. My current company, but different team, still has a quite a few recs out for C++ devs.

TL;DR - at least in my little bubble, the C++ systems engineer market has been consistently hiring people, though good engineers are hard to find.
