I'm also a manager and came here to say the same thing. Senior is a terminal level at plenty of mature companies. If you're in the startup world, you'll probably face big pressure to take on a Staff+ or manager title, but you can certainly successfully push against that if you have good rapport with the leadership team. I knew several engineers with decades of experience who were very happy being senior engineers in that world. They had their niches and knew them well. One had been writing email systems since the 90s, for example.
