What Does a QA Engineer Do?

A QA engineer is responsible for performing systematic manual and automated tests on products to identify bugs and errors, reporting results to stakeholders, and creating new testing protocols. Keep in mind that the specific tasks you’ll find in a QA engineer job description will vary depending on the employer and position on the team.

In many cases, a QA engineer’s responsibilities begin before a project starts. QA engineers collect information about the goals of a project and write policies to prepare for testing. They also set up processes to ensure the code has been reviewed and checked. Here are some examples of the duties included in a quality assurance engineer’s job description:

  • Coding automated tests

  • Creating software test plans

  • Discovering bugs or problems within a program

  • Developing standards and policies to ensure high-quality code

  • Identifying any problems that users may encounter

  • Performing automated and manual testing

  • Tracking test results

  • Documenting test cases

Quality Assurance Engineer Job Responsibilities

As you might expect, creating new software products is a complicated process, and quality assurance has a role to play each step of the way. Below, we discuss different forms of testing to give you a better idea of what a QA engineer does. 

System Testing

System testing is a form of quality assurance done on a full project. It’s typically conducted towards the end of the development process. Systems tests ensure all components of the software function properly, both separately and as a whole. It’s essentially the last test done before the product is released into the market.

Integration Testing

Integration quality assurance testing explores the various components of an application. First, it evaluates how the individual component works. Then, each component is tested to see how the application works as a whole. Integration testing is often done before system testing.

Feature Testing

Feature testing is a form of QA engineering done before an application is updated. This type of QA engineering explores how a new update impacts an application. QA engineers performing this work must find any issues or negative user experiences that come from the updated software.

Usability Testing

QA engineers test the usability of a product before its release. Usability tests ensure the product functions in the way a customer expects. These tests allow the team to see how well the product is received and to make whatever final changes are needed before the product is launched.

How Do I Become a QA Engineer: Step-by-Step Breakdown 

To become a QA engineer, you will need a working knowledge of software development as well as experience with automated and manual testing methods and technologies. Some QA engineers pursue a degree in computer science or a similar technical field. Others teach themselves cheaply how to code without any formal education, through bootcamps and courses. 

If you want to learn how to become a quality assurance engineer, here is a step-by-step guide to get you started.

Step 1. Choose an Educational Pathway

Getting an education is an important first step to becoming a QA engineer. Gaining a quality engineer degree is still the most common method, and is preferred by some employers, but it is not the only option. QA degree programs are more comprehensive but require more time and financial investment.

If you are looking for a more streamlined means of starting a career as a QA engineer, consider coding bootcamps or online courses. QA bootcamps are short, immersive programs designed to prepare students for entry-level jobs in tech. Ultimately, the right educational method for you will depend on your unique situation, career goals, and resources.

Coding bootcamps help you develop your technical resume through career services and counseling.

A portfolio and technical resume are especially important if you don’t have any professional experience working in a tech field, as QA engineers often spend a year or two working as software developers before moving into a quality assurance role. You’ll want to show employers the projects you have completed on your own to prove you have the skills they are looking for. 

Step 4. Start Preparing for QA Engineer Interviews

To prepare for a QA engineer interview, you’ll need to make sure that you aren’t just able to use QA tools, but that you are able to clearly describe your ideas and processes out loud. QA engineers work with members of every part of a development team, making interpersonal skills and collaboration all the more important. 

Practice common QA engineer interview questions in a way that emphasizes your problem-solving skills and attention to detail, review testing terminology, and make sure you are prepared to talk through your answers to technical questions. 

Step 5. Start Applying for Open Positions

By now, you should be ready to start applying for quality assurance positions. If you don’t have relevant work experience, you may want to begin your job search by looking for entry-level development positions or QA internships. It’s a lot easier to find employment as a QA engineer after you’ve gained some experience. 

Some people take on tech internships while attending college to ensure they have in-field experience on their resumes. Many coding bootcamps give students hands-on experience in QA engineering before they graduate, and most have extensive networks with hiring partners to help students get hired. 

Essential Skills for a QA Engineer
