Without knowing more about you it seems like you are having issues communicating your experience and how valuable that is.

We just closed two positions on my team with that exact requirement (BE + Infra) and it was not super easy as most people with that experience are looking for "higher" positions than individual contributors. A lot of places need good IC's who can execute so I doubt the issue is that you have too much experience.

I would try to re-frame your experience as being one who can guide, mentor and help elevate the whole team you are part of.
