My Dad is a retired R&D chemist who retired after 30 years at a company you've definitely heard of. When I was at university and applying for my first real jobs, he always stressed to avoid "job hopping" because it signalled unreliability. He still thinks that way, but the fact is that career strategy is dated, especially in technology. It's not uncommon for SWEs to change jobs every 2-3 years, and nobody will bat an eyelash or look down on such moves. In fact, most companies expect it nowadays. Oftentimes, the easiest way to get a significant increase in total comp is to get a new job instead of asking for a raise. That said, if you're happy where you are and you feel that you're being treated fairly, there's absolutely no reason to move on.
