Pros
Extremely high technical expertise. Very broad range of topics and areas of Embedded Security. From the silicon (and literally physics) to the app, to the device, to..the rest. Projects can be extremely varied and out of the typical projects you may find in other companies. Top notch equipment is available and world leading tools are used (and created!) projects. The environment is friendly, creative, relaxed and people are extremely willing to share knowledge and help. Work/life balance and employee well being are priorities for the company culture. In such multinational and multicultural environment, everybody seem to the get along just as fine as it could. Things like team competition and discrimination are outside of the company culture. On the contrary, you may find yourself staying late, just because you like the environment, the challenges and the friends. You get the feeling to be part of a group of friends, who just happen to challenge security in such a natural and sophisticated way, like it is almost seen only in movies. The tremendous boost of knowledge, the great challenges, the broad and varied projects and the great environment make it a really unique place where to work, grow and live in.
Cons
Growing, and even more growing fast, bring the usual "growth pain" to surface. The overall organization, such as in processes and approaches, has the need to adapt quickly to such fast growing track, while still retaining its culture Although this is natural, it may require some more energy and patience than in larger and already settled organizations.
