Pros
Diversity of interesting projects, fantastic work culture, reasonable workload, smart co-workers, excellent onboarding and support staff. Wonderful benefits (including employee ownership). Fantastic coffee machine. No giant egos, despite a long track record of success. Low turnover. People are given equal voice, organization feels very flat.
Cons
The company is not flashy, which some might see as a con. It's also not widely known outside of water resources circles.
