Prós
The opportunities to work with smart, talented people are fantastic. Some of the projects are very interesting while others will have you working on very old technology.
Contras
They use proprietary tools in lue of industry standards. This can have a negative effect on productivity and on career growth for employees. If you can deal with the limited exposure to industry standard tools and can adjust to the command/control management style of the founders then this may be a good home for hardware engineers. CPU Tech is not a good environment for software engineers if they wish to actually build new software that impacts the success of the company. Most of the software is built using out-dated technologies. You will be stuck in the mud for a long time.
