Not OP but I would say, generally non-engineering things that keep the business people happy. Project planning, delegating tasks, dashboards and metrics (customer feedback, if you can acquire it, is a big plus), setting and meeting deadlines, and knowing how to sell yourself.

There's that old (and very true) wisdom that if you solve a complex problem in two days, the business people won't think "wow, this guy is so smart and hard-working for solving that in 2 days." They will think "oh, this problem must not have been very hard to solve. Let's assign him extra work." Being a good engineer only gets you so far, career-wise.

Writing ample clear documentation, precision of communication, dutifully fulfilling all timesheets, logging of work performed, attending all requested meetings, and always delivering work on time.

The paperwork matters far more than the actual work. Having your Jira tickets (or whatever) up to date and highly granular, and organized into all the taxonomies of sprints/epics/etc, and of course actually communicating status with teammates, tends to be significantly higher-valued than any actual code you're getting done, at least as far as winning brownie points and promotions are concerned.
