Pros
If you can lay low and join a team with good people and a good manager (there are a couple), it's possible to be shielded from the politics for a short while.
Cons
Unfortunately, politics corrupt this company from the top down. The CEO and VPs often make promises to investors, board members, and the public to gain funding and company hype. The technical feasibility is an after thought, and a burden placed on the manager and employees of the team. When things are going well, expect that the VPs and CEO will be there to take credit; if things are going poorly, expect them to maneuver themselves out of the path of destruction and let their employees take the fall. I strongly advise future candidates to talk to people on their team before making any decision.
