Pros
You are working with some of the most experienced people in the payments industry. Experience at ACI gives employees both real-world experience with large banking/financial shops as well as a great background in the financial/payments world. Many opportunities for global travel. Though there have been a number of changes, it is still a reasonably casual work environment, and people are encouraged to seek out the help and mentoring of the more experienced people. Salaries are above average for the location (at least in Omaha). Competitive benefits package.
Cons
Senior management has taken a number of steps recently in late 2008 to put more processes in place around the business. Some of these steps were definitely needed, but they have been done speedily and in a disorganized way, leaving people on the floor confused about their roles and ultimately their worth to the company. At this time, February 2009, the pressure to put in long hours, more than 50, is great. Hopeful that this will change after some of the recent changes settle down. Because of that, all of that great experience is not being put in the areas where they can help the most.
