Meaning is incredibly fickle, certainly not an inherent quality of pretty much any work.

The work you do today seems to enable a range of businesses to get on with doing whatever it is they do by letting them leverage some incredibly powerful technology. That sort of enablement seems like something I'd find meaningful. But you're not me, and I'm not you.

If you want to work on more deep technical problems, for the sake of the technology itself (at the cost of being rather further removed from the real-world applications your work enables), go look for that, that's perfectly reasonable. But be careful about assuming that this will necessarily feel more meaningful.
