Pros
Flexible schedule, with telecommuting (1 day a week) and flex time in the summers (4 day workweek with 30 min lunch). Friendly and knowledgeable team. More women than you usually see in development! Good health insurance, retirement package, vacation/personal/sick time, and other perks like free on-campus physical therapy and fitness classes.
Cons
Like any higher ed job, this pays less than the industry average. Wellesley tries to stay competitive with the other prestigious liberal arts colleges, though. Things are starting to get more modern, but until recently, they used a lot of older or highly customized technology. Not the highest morale among employees, people generally seemed stressed, but people are still able to unplug and be with their families at home and are very rarely required to work overtime.
