Pros

Almost everyone that works here is dedicated, smart, and thoughtful. Projects are often very impactful and give great visibility to leadership. I feel that I have excellent work/life balance and I am able to be flexible with demands at home (I have a 3 yr old).

Cons

This is not the place for someone who doesn't deal well with ambiguity. As a young thriving startup, we are still working on setting foundational process and methods in place and this requires great patience as well as endurance/stamina to be able to get through projects and initiatives without all the concrete foundation that an older company has.
