Cons
AppNexus has comprehensive difficulties transitioning from start up to enterprise/corporate model. It seems to have lost it's soul somewhere along the way. Initially when I worked there I worked in a flat motivated team, however the team structure become increasingly hierarchical, bureaucratic and political. Senior team members tend to leave NYC, work remotely and lose touch with the workings, needs and aspirations of the wider team. For UX Designers and Researchers the AppNexus Console is uninspiring subject matter. It is devoid of emotion and constrained by an unimaginative pattern library. AppNexus products suffers from a significant UX debt. Many AppNexus products actually have little or no UX input. Many of the projects that UX are involved in have a have a minimal amount of UX design engagement and testing. The UX research team for AppNexus, a global company of well over a thousand employees consists of only 1 full time UX researcher. Also there is no formalized UX process to understand how well features fare when in Alpha or Beta. In addition there is virtually no UX process to assess how a well a feature is doing in production. For a career in UX AppNexus at best is somewhere to get some experience on your resume while you keep an eye out for better opportunities else where in NYC.
