Hey, and thank you for posting your questions.  I am one of the Ice wall watchers. there are many of us posted along the earth. My particular position is confidential unfortunately. The money is quite nice for being one of the many watchers along the walls. Basically what i do is, maintain the order and stability of these walls. I do have a house out on the post of these part of the wall, Made out of icebloacks i have taken from part of the wall. normally they will re-generate themselves rather quickly do the colder climates at earths end.  I have a picture of me inside my part of the wall. its quite beautiful I have run into some problems with people trying to use explosives on the wall. unfortunately i had to use some firepower, becuase i had been fired upon. cant go any further than that. Anyways, i sometimes go through the wall to the other side, i have made path through the wall, so i can get a nice view of space from the edge. i have pictures of the edge as well as the space pictures from the edge.
