Quality assurance is one of the most accessible ways into the software industry — and one of the most underestimated. A good QA engineer does far more than "click around and find bugs". They protect users, save the team time and money, and help everyone ship with confidence.
If you're thinking about a career in QA, here's what the job actually involves and how to get there step by step.
What a QA engineer really does
At its core, QA is about reducing the risk that software fails the people who use it. Day to day, that usually means:
- Understanding requirements — and asking questions when they're unclear, incomplete or contradictory.
- Designing tests that cover the important paths, edge cases and risky areas.
- Executing tests, both manually and through automation.
- Reporting defects clearly enough that developers can reproduce and fix them quickly.
- Improving the process so fewer defects are created in the first place.
Testing finds problems. Quality assurance prevents them. The best QA engineers do both.
1. Build the right mindset first
Tools change every few years; the mindset doesn't. Great testers share a few traits:
- Curiosity — "What happens if I…?" is your most powerful question.
- Healthy scepticism — "it works on my machine" is a starting point, not a conclusion.
- Empathy for users — think like a first-time user, an impatient user, and a user on a slow phone.
- Clear communication — a bug nobody understands is a bug nobody fixes.
2. Learn testing fundamentals
Before you touch automation, get comfortable with the basics:
- The software development lifecycle and where testing fits in agile teams.
- Test levels: unit, integration, system and acceptance testing.
- Test types: functional, regression, smoke, exploratory, performance, security and usability.
- Test design techniques: equivalence partitioning, boundary value analysis, decision tables and state transitions.
- Writing test cases and bug reports that are concise, reproducible and prioritised.
Tip: The ISTQB Foundation Level syllabus is a free, well-structured map of these topics. The certificate itself is optional, but it's recognised by many employers — especially in Europe.
3. Get technical, step by step
Modern QA roles increasingly expect some technical skills. You don't need all of them on day one, but aim to learn them in roughly this order:
- Browser DevTools — inspect elements, read console errors, watch network requests.
- SQL basics — verify that data was actually saved correctly.
- API testing — use Postman or similar tools to test REST endpoints directly.
- Git — every team uses version control, and so will you.
- A programming language — JavaScript/TypeScript, Python or Java are the safest picks.
- Test automation — Playwright or Cypress for web UI, plus a unit test framework in your chosen language.
- CI/CD — understand how tests run automatically in pipelines such as GitHub Actions or GitLab CI.
4. Practise on real software
Theory only gets you so far. Build experience you can talk about in an interview:
- Test public practice sites built for testers and write up what you found.
- Pick an app you use every day and do an hour of exploratory testing. Note every issue and how you'd report it.
- Contribute to open-source projects — many welcome bug reports and test improvements.
- Join crowdtesting platforms to test real products and earn small payments for valid bugs.
5. Build a small portfolio
A GitHub profile with a couple of tidy projects says more than a long CV. A strong beginner portfolio might include:
- A test plan and a set of test cases for a real website.
- Three or four well-written sample bug reports with steps, expected vs. actual results and screenshots.
- A small automated test suite (for example Playwright tests for a demo shop) running in CI.
- A short API test collection with assertions.
Add a README to each project explaining what you tested, why, and what you'd improve next. That shows judgement, not just tool knowledge.
6. Land your first role
Look for titles such as Junior QA Engineer, Software Tester, QA Analyst or Test Engineer. Internships and trainee programmes are also great entry points. In interviews, expect to:
- Explain how you would test an everyday object or feature ("How would you test a login page?").
- Walk through a bug you found and how you reported it.
- Discuss the difference between priority and severity, or between verification and validation.
- Read or write a simple automated test.
Moving internally is also a common path: people in customer support, business analysis and operations often already know the product deeply, and that makes them excellent testers.
7. Keep growing
Once you're in, QA offers many directions to grow:
- Test automation / SDET — building frameworks and tooling.
- Performance or security testing — specialist, high-demand niches.
- QA lead or test manager — strategy, people and process.
- Quality engineering and consulting — helping whole organisations deliver better software.
Keep learning from the testing community: read blogs, follow practitioners, attend meetups, and try AI-assisted tools for test design and analysis. They won't replace a thoughtful tester, but they can make a good one much faster.
Key takeaways
- Start with mindset and fundamentals; tools come second.
- Learn technical skills progressively: DevTools → SQL → APIs → code → automation → CI.
- Practise on real software and turn it into a small portfolio.
- Communication is a core QA skill, not a soft extra.
