How to Learn Quality Assurance Engineering

The software industry has come a long way from mainframes and programming languages like COBOL to today’s modern digital achievements. Developers now often also work as quality testers, since code must be written correctly in order for a program to work. To become a quality assurance engineer, you must be creative and thorough, utilizing a range of skills to make sure products are up to speed.

As a quality assurance engineer, you must find unique ways to make a product work. With many companies trying to preserve their legacy as successful tech innovators, quality assurance engineering will always be relevant. 

What Is Quality Assurance Engineering?

Quality assurance (QA) is the process that a business puts in place to ensure that a product is up to customers’ standards. It is a way of organizing all aspects of production and operations to ensure the quality of products and services.

A QA engineer must examine every aspect of the production process, starting from the design and development stage.

The tasks of a QA engineer include developing procedures for internal feedback and carefully monitoring projects to uphold quality standards.

Quality Assurance Engineer Skills

A QA engineer must have great managerial skills. They need to be skilled at verbal and written communication in order to convey messages across all levels of an organization.

Skills in data collection, analysis, and management are also very important in QA engineering. Apart from these, a QA engineer should also be excellent at teamwork and working with clients.

Thorough Understanding of Concepts 

A QA engineer must have a background in a variety of technology, as they may have to monitor projects in different fields. As a QA engineer, you should be well-versed in several programming languages.


An understanding of the data management language SQL and of relational databases is necessary. A QA engineer will need to search databases to mine test data or to validate the results of a test.

Knowledge of Tools

In some organizations, knowledge of automation and CI/CD (continuous integration and continuous delivery) are essential. In this case, the QA engineer will need to know how to use software such as QTP, Selenium, and Jenkins.

What Is a Quality Assurance Engineer?

Depending on the industry, quality assurance job responsibilities can differ greatly. But the main task of checking if a product meets requirements in quality, authenticity, and efficiency is the same.

QA engineers implement policies and procedures to ensure standards, and take the initiative to plan, monitor, and inspect materials. These professionals are also charged with compiling data regarding product quality. 

Lastly, QA engineers must also investigate any product complaints raised by customers or clients, and document the outcome. 

Duties of a Quality Assurance Engineer

A QA engineer tests features of products that they are working on and advocate for quality improvements. Some basic responsibilities of a QA engineer are listed below.

  • Document control. Reviewing, formatting, and updating documents, as well as archiving them is a key role of a QA engineer.

  • Audits and inspection. The engineer must organize in-house audits and inspections, system audits, and take corrective and preventive actions.

  • Conducting OOS. An OOS is an Out-of-Specification test. It is used to test code and informs the QA engineer of any results that are not of the desired quality.

  • Change management. QA engineers have to review change proposals to increase funding. Then, they must authorize and implement the necessary changes. 

Quality Assurance Engineer Job Opportunities

QA is all about finding issues with a product before it gets to the customer. The intensity of a QA job will vary depending on what type of software you are working on. For example, companies that make life-saving software are very serious about locating and eradicating bugs.

Almost every IT company has testers, and the opportunities for skilled testers are increasing as competition between companies heats up.

Although many start-ups and small-scale companies also need QA engineers, the ground-breaking work in this field is done at bigger companies. Some of the top companies that hire QA engineers include Google, Uber, Apple, Amazon, and Facebook.
