What is a QA/QC Engineer? 6 minute read

The primary function of Quality Assurance/Quality Control Engineers is to ensure the quality of their company’s products by participating in each stage of a product’s creation, beginning with development and ending with packaging. In addition to upholding the standards of their company, QA/QC Engineers must also adhere to product quality and employee safety standards set by state and federal laws.

QA/QC Engineers typically work in factories, plants or the offices of technology companies, and usually report to a small number of higher-level executives while simultaneously supervising a large number of lower-level workers. QA/QC Engineers are employed in a variety of sectors, including software, aerospace, automotive, architecture and electronics manufacturing. According to the Bureau of Labor Statistics, demand for Industrial Engineers, which includes QA/QC Engineers, will decline by 4 percent, resulting in the loss of 6,300 positions through 2024. This decline can be at least partially attributed to the decline of manufacturing in the United States in general. However, it is worth noting that these statistics do not account for QA/QC Engineers who work in technology, which is a rapidly growing industry.

QA/QC Engineer Q & A

If you’re thinking about pursuing a career as a QA/QC Engineer, you’ll want to hear what Daniel Dragonov has to say. Dragonov is the head of the QA division at the software company Kanbanize, and we spoke with him in order to get an insider’s perspective on what it’s like to be a QA/QC Engineer.

What are some of the core duties performed by a QA/QC Engineer?

Among the core duties I perform are daily inspections and testing of the scope and character necessary to achieve the quality of the features our R&D team develops, carrying out inspections and checking for all quality related procedures we have adopted, taking care of QA/QC documents of the entire project including test results, [addressing] inspection requests, etc.

What challenges does a QA/QC Engineer face?

The biggest challenge for me has always been to uncover every possible defect in the software. There are a ton of things that could go wrong in the last moment, and often functions that worked at some point get broken without any clear indication as to why. Another difficulty is the pushback we sometimes encounter from people who are averse to change.

What skills do QA/QC Engineers use the most?

Important skills I would point out are the knowledge of how the application under test fits together from a big picture perspective, how a change made to one part of the application impacts other parts of the application, the ability to read and interpret written documents with a critical eye [and] asking questions in order to better understand them.

What should someone consider before becoming a QA/QC Engineer?

Every person who considers applying for such a position should be aware of the responsibility and stress that come hand in hand [with the job]. Staying in the office overtime is something that is common for me and my colleagues. Knowing that if you miss something during testing it will reflect on the whole company is another thing that is not easy to get used to.

What type of person is sucessful in this job?

Someone who is persistent and very patient. Sometimes issues are more complex than they look and often they are not easy to spot at first sight.

What do you find to be the most rewarding aspect of being a QA/QC Engineer?

Being able to make a difference. To see each issue as an opportunity to change for the better.
