Pros: Mission-focused organization with strong co-founders who have worked hard to create a family friendly environment with a welcoming culture and great benefits. This is a place where you can grow your career if you're eager to learn and willing to put in the work.
Cons: You will work hard here. As with most startups, people are asked to wear a variety of hats and chip in to work towards the company's goals. If you're looking for a job where you can just coast, this isn't it, but the work is rewarding and meaningful.
