I've been tech lead at different companies. Every time I switched companies, I started out as senior dev and got promoted into the team lead role again; each time with full support of my team.
I don't look or act like a leader and this has been a hurdle for me. But what typically happens anyway is; within a few months, my code ends up being a core part of the project; my modules become heavily depended upon and somehow I end up maintaining all the config files and guiding architecture decisions. One of my team members joked that I "conquered everyone's code." I probably write fewer lines of code than everyone else but somehow those lines end up heavily used. So then I basically just ask the big boss for a team lead position.
