I hesitate answering because I am not really a software engineer, but I think a strong understanding of philosophy will probably help. I see a lot of other comments in this thread recommending empathy, organizing, hermeneutics, etc. Most of that goes under the admittedly large umbrella of philosophy.
Software engineering/programming is somewhat distinct in most fields because you can by some abstraction recreate and scale a thought with high fidelity. In the past, we could transfer or spread thoughts through books or other media. This might've created some sort of mimetic action on the consumer of the media, but it would probably be some corruption of the initial thought of the author. Consider for example, Marx claiming that "what is certain is that I myself am not a Marxist" (not that I am intending to start a political discussion, just to point out that sometimes artists distance themselves from the art). By contrast, a computer program is a thought that is enacted with precision each time it is called. Which is what makes the content of program so philosophically important. Ethics of course becomes paramount because speech is now action in a much more salient way than it ever was before. But the questions of values and of aesthetics should also be considered.
You will probably have to carve out your own fields of study within philosophy and how it relates to computer science beyond the usual accelerationism, trolley car problems, digital physics, etc, but I think it will be well worth it if I'm just giving my two cents here.
