I like working for people like this, because often they look to increase both quantity and quality of the people they manage (if they can call you a senior engineer, then that must make them a senior manager). So they're often quite a good advocate for your career.
They're focused on me and the other engineers, we're focused on the product, and everyone is happy.
That contrasts with product focused managers, where I've seen a tendency to burn through engineers and be very stingy with raises and promotions. So the engineers need to take time to be their own advocates and set boundaries and lot of us aren't as good at that so it becomes chaotic.
I've worked in teams where 'seniors' were given to us by this kind of managers that were more like juniors so my personal experience has not been as good as yours.
