Ask HN: Has anyone here worked on the Windows kernel?

Or any other kernel, professionally? I've been offered a position at Microsoft to do kernel development work. This would be a big transition to me, coming from a services background (backend only). The job's main draw to me is doing low-level work. I did some in my very first job, but for the past 10+ years, due to a number of circumstances, I've been in the services world. I really liked being a C programmer and I've kept an eye on things over the years, and did some hobby projects (on x86 and some embedded stuff as well). There's a lot about my current job that I treasure, despite the work itself not being interesting to me about 99% of the time. It's a remote job, the work-life balance is stellar, and I get 25 days of vacation a year (this is in the US), which allows me to spend a lot of quality time with my wife. However, I'm considering leaving because I've been having significant motivation and performance[0] issues for the last two years.
