A quality assurance (QA) job involves testing products or software to find defects before they reach customers. QA professionals review requirements, create testing plans, track bugs, and work with developers or production teams to fix problems. These roles exist across nearly every industry, from tech companies shipping software to breweries inspecting beer and healthcare organizations verifying compliance with regulations.
What QA Professionals Do Day to Day
The core of any QA role is finding problems before someone else does. In a software setting, that means reviewing product requirements, writing test cases, running those tests, and logging every bug you find in a tracking tool like JIRA, TestRail, or Bugzilla. When a developer pushes a fix, you verify it actually solved the problem and didn’t break something else.
In manufacturing or food safety, the work looks different on the surface but follows the same logic. You might inspect physical products for defects, monitor production processes against standard operating procedures, and flag anything that doesn’t meet spec. A QA technician at a brewery identifies non-conforming product on the line. A QA specialist in cannabis production inspects medical products and monitors compliance with process requirements.
Regardless of industry, QA roles share a few universal responsibilities:
- Creating and running test plans that systematically check whether a product meets its requirements
- Tracking and reporting defects with enough detail that the team can reproduce and fix them
- Identifying root causes so the same type of defect doesn’t keep recurring
- Building inspection workflows that make the testing process faster and more consistent
- Training other team members on QA processes and quality standards
Teams typically measure QA performance with a few key metrics. Defect detection rate tracks the percentage of bugs found during a testing cycle. Time to resolution measures how long it takes from identifying a defect to fixing it. Defect leakage rate captures how many issues slip through testing and reach users, which is the number everyone wants to keep as close to zero as possible.
Manual Testing vs. Automation
Software QA splits into two broad specializations, and understanding the difference helps you figure out which path fits your skills.
Manual testers work through an application the way a real user would, but with a destructive mindset. They’re looking for edge cases, unexpected behaviors, and things that feel wrong even if they technically “work.” The key skills here are risk analysis, exploratory strategy, and the willingness to go off-script when something seems strange. Manual testers often catch problems that automated tests miss precisely because they aren’t following a rigid checklist.
Automation engineers write code that runs tests automatically, usually hundreds or thousands of them, far faster than any human could. This role requires programming skills. Modern automation engineers typically work with JavaScript or TypeScript and tools like Playwright or Cypress, which let you write functional tests in minutes rather than weeks. You’ll need to understand how web pages are structured (the DOM and locators), how to write assertions that check for correct behavior, and how to handle timing issues with waits so tests don’t fail just because a page loaded slowly.
These are genuinely different skill sets. Manual testing rewards curiosity and critical thinking. Automation rewards programming discipline and systems thinking. Many teams need both.
QA Outside of Software
If you search for QA jobs, most results will be software-related, but quality assurance is a broad field. Manufacturing QA roles focus on physical product inspection, process compliance, and preventing defective items from shipping. Healthcare QA analysts verify that applications meet regulatory requirements and that organizations maintain data integrity for funder reporting. Nonprofit QA roles might involve monitoring program quality and ensuring compliance with supportive housing standards or grant requirements.
The common thread is that every industry producing something, whether it’s code, a physical product, or a service, needs someone making sure the output meets defined standards. The tools and terminology change, but the analytical mindset stays the same.
Education and Certifications
Most QA positions ask for a bachelor’s degree, though the specific field varies. Software QA roles often prefer computer science, information technology, or a related discipline. Manufacturing QA may look for engineering, chemistry, or biology backgrounds depending on the product.
Certifications can strengthen your resume, especially if you’re breaking into the field without a directly relevant degree. The most widely recognized credential globally is the ISTQB Foundation Level Certification (CTFL), which covers fundamental software testing principles and terminology. It serves as the entry point to the profession and is a prerequisite for all other ISTQB certifications.
Once you have the foundation credential, you can specialize. Some of the most relevant certifications for 2026 include:
- ISTQB Test Automation Engineering for designing and maintaining automated test solutions
- ISTQB Agile Testing for working effectively within Agile development teams
- ISTQB Testing with Generative AI for using AI tools in testing without producing low-quality output
- ISTQB AI Testing for professionals who test AI-powered systems
- ISTQB Mobile Application Testing for the specific challenges of testing on phones and tablets
For non-software QA, the ASQ (American Society for Quality) offers certifications in areas like quality engineering, auditing, and Six Sigma that carry weight in manufacturing and process-oriented industries.
Salary Ranges
QA engineer pay in the United States varies significantly by experience. According to Glassdoor data for 2026, entry-level QA engineers earn between roughly $43,000 and $83,000 per year. The overall average sits around $101,000, with the middle 50% of earners falling between about $78,000 and $133,000. Senior QA engineers with at least five years of experience can earn between approximately $103,000 and $186,000.
Automation skills generally push you toward the higher end of these ranges because the role requires programming ability on top of testing knowledge. Industry also matters: QA roles at large tech companies or in regulated industries like finance and healthcare tend to pay more than similar positions at smaller organizations.
Skills That Get You Hired
Beyond certifications and degrees, hiring managers look for a specific mix of technical and analytical abilities. On the technical side, you’ll want proficiency in at least one testing method: functional testing (does the feature work as specified), regression testing (did recent changes break existing features), usability testing (is the product intuitive), or automated testing.
You should be comfortable writing clear, reproducible test cases and working with defect tracking tools. For software roles, basic familiarity with code is increasingly expected even for manual testers, since you’ll need to communicate effectively with developers and read log files or error messages.
The soft skills matter just as much. QA professionals are essentially professional skeptics. You need the kind of mind that looks at a finished product and immediately starts thinking about what could go wrong. You also need strong communication skills, because finding a bug is only useful if you can clearly explain how to reproduce it and why it matters. Training other team members on quality processes is a routine part of the job, so being able to teach and document procedures clearly will set you apart.
