The positions I'm looking at are just with another group, that is actually pretty closely aligned/related to my current group. We are encouraged to move around, and change positions every 3-5 years, and I'm going on 5 years in this role, so it is pretty much expected that this move should be happening soon. The reason I haven't done it yet is because I generally really have liked the work I am doing now.
Now I need to figure out which position to apply for. There are 2 I'm considering, one that is a little bit of a reach, based on my experience, as it asks for 10 years experience, but I knock all other requirements out of the park, probably enough so that based on my resume I'd be the most qualified one applying. The other has almost the exact job description, but it is less responsibility, one pay grade lower, and only requires 4-6 years experience. I really want to go for the bigger role, as I feel I am qualified, but I don't want to look silly in front of some pretty big-time managers for applying and interviewing for a position that is over my head. Not sure what to do.
