Ask HN: What should I have my new title be?

My current title is front end engineer. My boss wants to give me a title change/more responsibility. I'm pretty much allowed to frame my title any way I want. So I would like to see what would be the best title change for my resume and allow me the greatest flexibility in the future:

Senior Front End Engineer Front End Technical Lead Lead Front End Developer

Or some other permutation? Thanks in advance for any input.
