Pros

Truly love working at CIO. I have been given so much autonomy and opportunity to really own my work and help shape the outcomes, not just execute tasks. I have the ability to directly influence my team and leadership, giving my role true value and meaning. We are doing really incredible things here and great to be part of such an innovative company. Leadership is approachable and transparent.

Cons

Can be fast-paced with a startup mentality which may not be for everyone.
