I 100% agree with this. Big tech jobs, or those at medium sized firms, are easy to coast in. I've heard that at some FAANG companies Senior SWE can be viewed as a terminal level and it's totally acceptable to have a flat career trajectory here. Consistent, stable, and reliable salary with an average amount of work sounds good to me, you just need to have a high tolerance for BS.
This is really important. You will spend your whole life aligning stake holders. If you can't stand that and started searching for meaning of life then eventually you end up quitting.
