I love that I'm not stuck at a desk all day. I do have a desk, but I barely use it. Most of the time I'm out on site, moving around, working with my hands, building and fixing things.
I also really enjoy the variety – no two days are the same. One day I might be helping build a particle accelerator and the next I might be in the clean room working on parts for a piece of equipment going all the way to America. It feels exciting to be part of such big things, even when the work is really precise and technical.
