I've taught calculus in college, and currently work in tech. I think the point of calculus in college is to give new minds a vocabulary and intuition for processes involving rate of change. I've never had to solve an integral symbolically at work, but I have had to write code to implement variations of gradient descent, which utilizes derivatives, and I've written code to sum different sensor measurements to estimate spatial location, which is basically integration. Long story short, I don't use calculus "out of the box", but it gives me a framework for thinking about things.
