That vendor-integration (and vendor-relationship-management), rapid task-switching, ops / support description sounds exceptionally familiar. It's what I view as more a dev/ops role, though it's also somewhat the old-school Unix-class sysadmin model. Someone who's familiar with compiler and scripting tools, and writes a fair bit of glue, but who is mostly building systems out of component parts, rather than coding them up from scratch.

It's the task-switching and firefighting elements of that position which tend to dominate, and which I've found increasingly untenable (at least to my own personality) with time. I need the long, clear timeblocks in which I can actually think.
