There are are lots of them. OS/database design, new computer graphics, robotics, embedded. For example, I just checked front page of HN -- there are 2 submissions which involve non-trivial CS algorithms: "you.com" search engine, and "ancient secrets of computer vision" course.

Even if the primary output of the organization of the website, there are still places for algorithms -- for example one of my friends is involved with bringing data science algorithms into "production" -- while initial experiments can be done in the Python with Jupyter notebook, you often need to rewrite the algorithms into high-performance language of your choice.
