Ask HN: How can I influence tech leadership in my org as a Senior Developer?

I work as senior developer in a Moderately big tech company​, with 3000 employees worldwide. I really like working here. I sorta love my employer. I really want to contribute towards its success in whatever capacity I can. Currently I do it by trying to produce the best quality software I can. I care deeply about training new people. I evangelize good engineering practices. But I feel I can do more, but I am not sure what. I am an OK leader. I would like to develop the tech leadership to help my company grow.
