> because it's developers that make it in the first place

I've inherited quite a few projects riddled with novice code; and code by developers who just fundamentally didn't understand critical concepts.

Especially as a newcomer, this is a topic that needs to be handled gently. Sometimes this requires correlating known flakiness with problem areas.

One word of caution: If the developers who made the debt are still in the organization, and oblivious to the problems they created, assume that your manager is also oblivious to the problem. It may be best to leave quickly, or feel out upper management to see if they agree with your assessment of problems.
