Pros
Laid back working environment, generally hands-off management, Flexible schedule (but you must work on-site). Decent benefits. Good for students. This job is a rut disguised as a hammock. You think you're relaxing in a hammock. You won't be micro-managed and are given plenty of autonomy. Lots of down time in-between work tasks. But your life is wasting away as your skills atrophy. Years pass as you're stuck in a rut.
Cons
Low pay. Management finally adds a cost of living adjustment commensurate with similar positions in the local job market, and acts like it's an undeserved, incredibly generous raise. Zero investment from the company in your career. No career path. Very little training or documentation for the systems you'll be responsible for maintaining. Scope of work keeps expanding, but the pay does not. Chaotic organizational structure and communications norms which causes unnecessary drama and extra work. Constant ad-hoc tasks from those in other departments who can't do their jobs correctly and are paid better than you.
