What's the difference between a quality engineer and a quality engineer?

They are different, and the main differences are as follows:

1, quality engineer QA is the abbreviation of English QUALITY ASSURANCE, which means quality assurance in Chinese. It is defined as "all planned and systematic activities implemented in the quality management system, and verified as required to provide sufficient trust to show that the entity can meet the quality requirements". Some organizations that implement the quality management system will set up such departments or posts to be responsible for the quality assurance functions required by the quality management system standards, and the personnel who hold such jobs are called QA. Similarly, QC is quality control, that is, inspector; QE is a quality engineer.

2, quality engineer, that is, in some organizations that implement the quality management system, is responsible for the quality assurance function required by the quality management system standards. That is to say, the Quality Engineer (QE) is all planned and systematic activities implemented in the quality management system, and verified as required, so as to provide enough trust to show that the entity can meet the quality requirements.
