Directly? No. By definition firing people isn't in an IC job description.

Can an IC get a manager fired? Yes. Skip-level reviews and 1:1s usually paint a clear enough picture for upper management that the correct course of action is to fire the manager. The more senior the IC, the more weight their review carries.

Can a manager fire an IC? Not unilaterally. Again, skip-level reviews and 1:1s are there to help upper management evaluate how well the manager is doing their job. Feedback from other ICs is also a big part of it. Senior ICs are generally involved not just in the decision but as part of ensuring the underperforming IC is getting sufficient support so they can be fairly evaluated.

I'm sure systems like this have broken down at other companies, but it seems to work well enough where I've worked.
