I've been adding compost and mulch to my garden and flower beds regularly, and I'm a bit concerned about the dirt level getting too high. I understand that adding compost is important for enriching the soil, especially in the fall when nutrients deplete. But I'm wondering, do I need to remove some of the existing soil to keep it from mounding up? Should I take some dirt out before adding new compost?

In my experience, I find that I need to add compost or soil at least twice a year because my beds settle quickly. Just remember, it takes a long time for compost to break down and contribute to soil levels.
Compost breaks down and loses a significant amount of volume, which is why we supplement in the fall. It turns into a silt-like substance, so your levels shouldn't grow too high. If you're looking for alternatives, you might try mixing in some peat moss and perlite, as these retain moisture without decomposing as fast.
Usually, the soil naturally settles over time, so you may not need to remove anything at all. As the soil settles, topping it up with compost will help maintain the original level without making it too high.
