My responsibilities include the network (postmaster, hostmaster, planning and troubleshooting), software planning, security, training, purchasing, and hiring and supervising the student staff -- oh yeah, and a bunch of management stuff (more purchasing, budgeting, and going to too many meetings).
I have been working as a fulltime system administrator since December 1991. Before that I worked for the lab as a student sysadmin, and a Unix developer for Gould Electronics and Motorola in Urbana, Illinois. Just in case you are interested, my resume is online (in pdf format).
