As a model designer*, trainer** and builder***
I use maths all the time. Admittedly, a lot of mine is calculus and pure maths and I've not used a lot of solid or plane geometry in the last few years (but am doing some research at the moment for shits-n-giggles that needs a little plane geometry).

* I design the types of models that are used to decide whether or not you get a mortgage or a limit increase/decrease/cancellation of your credit card - both regression models and neural networks

** not lion taming, training of neural networks to ensure that they're producing the answer that'd be expected (normally by backpropogation)
