The other thing expectation is product and business focus. Understanding how what youre doing affects the business, making changes that solve business problems. It's cool to make something 10% faster, but the expectation is you understand that if spending your time elsewhere will increase revenue, youll do that. Often I've found the product team assumes a thing is impossible, but if you understand the problems the business is facing, you can recommend the solution they thought was too hard to even bring to the eng team.
Yea, there are more meetings than as a regular engineer, and probably do less "work", but i dont find it political and your impact is larger in that you are making every other engineer better, and more control and input on the business.
