I'd just like to encourage people to apply. I work with @cbanek on the LSST EPO team. Working on a large science project is amazing. Every day is interesting. There is a shared goal beyond just making money, similar to a startup with traction. The environment is pseudo-academic, which combines the best of academia and working for a national lab. The portal already has some design work done but is generally greenfield for technology choices. And last but not least Tucson is great and quite affordable.
