We’re preparing to bulk plant a bunch of tulips. The soil in our bed isn’t great, and the beds are flat. Should I mound them up
with additional topsoil when we do the planting? We're in Salt Lake City, UT. The flower bed faces south and gets shade from big established trees to the south and west.

They need sun so hopefully the trees don't shade them completely or only provide dappled shade. Tulips won't grow well in shade and will rot in poor draining soil.
You can mound it up with topsoil and compost. I am including a newer idea about how to plant tulips on top of the soil, too.
