Pros
Vertex takes the work life balance seriously and the people are great. You have a generous benefits package, onsite daycare and a very stable industry (Vertex is a tax company and you know what they say about death and taxes). Starting pay is pretty good too.
Cons
This is NOT the place for eager young minds. Vertex does not value education, passion, past success or recent achievement. The ONLY qualification that matters is experience. The development staff is the biggest abuser of this paternalistic mentality. If you want to be a manager, and you have not managed, do not work here. A "promotion" opportunity almost always go to an outside hire. They don't hire upper or middle management from within, and they do not allow resources to transfer preferring "organic" moves (this is what the HR rep told me) meaning you must stay within your department. I will probably go back in 30 years or so and ride till retirement, but be warned, if you value your professional life or you want to get ahead professionally, do NOT work here. You may get the job you apply for, but it will be the last job you ever get with Vertex.
