Pros
An opportunity to work on technology and problems that are being solved from the ground-up for applications and deployments that are unique, such as wireless networks in high speed transportation, large scale fleet offload and highly reliable wireless backhaul. Small sized focused teams ensure that you get to shoulder a lot of responsibility and get opportunities to work on core areas like distributed routing, switching, 802.11 and the linux kernel. People are helpful, sharp and cheerful. Seniors in the team possess in-depth technical knowledge and contribute on a daily basis. Politics of any kind is completely absent.
Cons
Senior management in US seems to lack a big compelling vision for the company in terms of the product, technology and the direction in which the company should be heading in the long-term future.
