Developer and marketer/technical writer - selling to other devs is a giant business now and it often takes devs to make that content.
Developer and SRE - we live in the world of huge scaled our saas businesses where there are always support issues too advanced to be handled by non-devs
Developer and project manager - everybody has worked with non-dev project managers and it’s usually terrible.
Developer and people manager - there are so many more eng manager roles than there used to be, and moving to the management side is a well worn path now.
Developer and product manager - you have to develop a lot of new skills but in this role a past life as a developer can give you super powers.
That said, I moved first into people management and then into running a small software company which sort of demands a little bit of all of those skills
