Pros
The company has great diversity, opportunity to travel to the far corners of the world, many intelligent people, and a great variety of work. It is easy to move from an engineering job to another area such as manufacturing, human resources, or sales. The company also provides decent corporate discounts at many businesses in the greater Houston area if you happen to work there. If you want to work at a company that will allow you to see the world in terms of work, people, and geography, this is the place to do it.
Cons
The company culture is very fickle. It seems like things are always changing: job positions, management structure, rules, policies, standards. In a technology development center this constant change is very disruptive and annoying. Most people I know have not stayed in any given office for more than a year. Additionally, there is a clear lack of overall resources. Most employees are doing several jobs at once: shipping packages one day, ordering supplies another day, traveling to a field location the next day, and writing a technical report a few days after that. If you like the feel of a startup, you'll get it here. This constant change means that no process is ever efficient and nobody has the time to do anything but get the big fires under control, which can be very stressful. It's not just the economy in 2009 that has caused it since this culture existed long before, although it has made it much worse.
