Shocking when you realize places like Amazon will be one L6 and ten inexperienced devs. The L6 will just absolutely micromanage the low yoe devs. So come up with a design for the whole team, break it into pieces, and then grill them on their small designs. The CRs go under the microscope. Sprint planning with some absurdly short estimate. This is how modern software development is done. And its unfortunate that for non critical services, you actually dont need that many experienced engineers.

This is why ageism is rampant, some 35 year old would never agree to this setup.

Either do it, or move to a critical service team where theres actual adults
