Depending on the field of engineering, add linear algebra to the list.
If you are an electrical engineer you will be doing fourier transforms all day long.
If you are a civil or mechnical engineer and are actually involved in materials, such as steel composition, you will be doing a lot of finite element analysis.
I am sure linear algebra is used in other engineering fields as well, but those are the two examples I know of.
Algebra and Geometry
I agree with the first two Responders, although I have never had to apply differential equations during my career in Civil Engineering. I certainly agree that a "basic level" understanding of Math will not be enough for a successful career in Engineering.

Not "basic" math. See first response ... and add one more: Differential equations.
