Pros
Advanced high-pressure technology, exposing one to unique end applications and industry leading companies in their domain. Being a smaller company there are opportunities to drive very impactful projects and efforts internally and externally.
Cons
Being a small company there are needs to "do" beyond what your title's roles and responsibilities capture. If you are a "doer" by nature not an issue, otherwise this could be a challenge for some especially coming from a larger company.
