Pros
Innovative company that is pushing the bounds of surgery. This company provides great opportunities for challenging work. Overall compensation package is good when considering salary, stocks, insurance plan, etc. Work life balance is fairly good, most managers don't expect you to work every weekend.
Kontras
Compensation may be a little too dependent on stocks, salary alone is probably lower than standard tech company salary in the bay area. The 401k plan is very weak (matching 200% on first $1500). As with most companies, promotions are less due to merit and more due to your management teams ability to sell your work to the VP level (even when you show great ROIs). Sometimes it feels that is more important to report your work than actually do it.
