I do satellites now but when I worked in insurance the work we did was meaningful. People need insurance, their policies are stored as data, and the company had to manage millions of policies.

Increasing click-through rates may not feel meaningful, but writing unit tests for a satellite which has already launched and been decommissioned will eat your soul, and you likely won't become a better developer because of it since you won't be given a budget to improve things or try new tech.
