The project manager of a software development team needs to hire someone to review every part of the software to make sure it works as intended. What position should he advertise for?

code reviewer

Explanation:

In this scenario, the project manager should advertise for a code reviewer. Usually a development team has at least 2 code reviewers that are very familiar with the code that is being written for the project. Once sections of code have been completed it is usually the case that both the project lead and a code reviewer both review the entire software to look for bugs and note improvements that can be made to make the code more efficient.
