Yeah, I sorta specialize in that whole IoT firmware update/fleet monitoring/make sure everything at the edge runs smoothly end of things, and if you find a company that realizes that this is something that MUST work smoothly if they're going to scale, then it's a very sweet place to be. Even better, that sorta work combines low-level C++ with lots of back-end web service work, so you're never 'just' a C++ programmer.
