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.
