I worked for my first company for a decade. I cannot stress enough how much this held my career and technical growth back. I got raises in that position - in one case a good one - but none of them compared to how fast my salary went up once I started hopping jobs from time to time.

I'm finally to the point after twenty five years where I'm making enough for the cost of living and I almost don't care about pay - it's much more about culture and finding a good team.

A 50% pay bump is unusual though. I'd expect more like 10-20% depending on the current market. I'm in the middle of a job search and I'll be damned lucky not to take a shave because there are so many laid off developers now. If someone offered me a 50% bump I'd take that in a heartbeat if there were no red flags. Although I'd need a massive freaking raise to go back to an office - QoL is so much better working remotely 90-100%.
