The type of programmer who specializes in the last step of the six steps of programming is typically known as a software tester or QA (Quality Assurance) engineer.

Detailed Explanation

1. Role of Software Tester: After a program has been designed, coded, and integrated, the software tester comes into play to ensure that the software functions as intended. They identify any bugs or inconsistencies, performing rigorous testing procedures to verify that all specifications have been met.

2. Importance of Testing: This last step is crucial as it directly affects the user experience and software reliability. Without thorough testing, software can have critical flaws that lead to failures in real-world applications.

3. Testing Types: Testers employ various testing methods such as functional testing, regression testing, performance testing, and others to validate the software.

4. Collaboration: Software testers often collaborate closely with developers, providing feedback that can lead to code revisions before final deployment.

In summary, while development encompasses multiple stages, it is the role of the software tester to ensure that the completed product is robust and ready for release, focusing on quality before the software reaches its end users.
