Pros

Lots of backlog and a variety of work projects available to employees. Most managers have been with Tt for the long term. Respected company by peer companies. Flexibility in work location.

Cons

Pressure from headquarters in CA. Acquisitions hard to digest within overall company. Many contracts are federal government based so you are dependent on politics for work.
