Pros
SiTime culture is all about encouraging people to be leaders and innovators. Any employee can discuss their ideas or concerns with anyone from direct co-workers to executives to the CEO. The company is also generally interested in having their employees succeed and is willing to work on training and in some cases accommodating employee's desires for role changes. However, expectations are high and schedules are tights, so employees who can't or are unwilling to keep up generally don't do as well.
Cons
Schedules are tight and pressure can be high at times. Projects tend to shift around, with people shifting from one project to another too frequently.
