Great research experience. Flexible hours, casual dress code.
Low pay, projects and experience vary greatly depending on which lab you work in.
Great salary and benefits. Minimal supervision from offsite supervisor. Enough meetings to have good colleague relationships. Flexible hours, some of it remote from anywhere. Fairly casual dress for... working with children.
The only downside is they are kind of famous for technical problems on the company issued iPads and iPhones. However, this is a known issue and technical problems have never been held against me, or... have slowed work during work hours, which are pretty flexible anyway. Some of the on-site staff are not exactly warm to this contractor position, but most are and I just steer clear of negative people. I do have a minor disability and the contractor site was not helpful accommodating me, but Leidos did try. That won’t affect most people.
