Linux system administration, preferably with HPC (but other sysadmin environments would be OK as well). Hope to make it clear to potential employers that my age shouldn't be a negative factor; i.e no worries that I'd stick around for only a year or two and then retire. On the contrary, I plan to continue working for at least five years, and probably ten years or more, before I even think about retirement.
