How to Be a Senior Engineer

In an ideal world, there would be some list of things like a senior engineer does this. This is how we know what a senior engineer is. It has a really detailed engineering ladder that contains a lot of their cultural practices. I don't think it's generalizable to everyone, but it's a great example of like a company that thought really hard about what defines these titles and what do you do to achieve them? And then they just apply that in reviews to determine what people's titles are and in hiring too.
