A QA tester checks software before customers do: they read what a feature is supposed to do, test it against those requirements, try to break it in ways real users will, report bugs with clear steps to reproduce them, and confirm fixes before release. Your product needs one when customers start finding bugs faster than your team does.

Many SaaS founders put testing off because developers can test their own code. They can, up to a point. Developers test the path they built. Testers test the paths nobody planned for, and that is where most production bugs live.

Below we cover what a QA tester does day to day, the difference between manual and automated testing, the two numbers that tell you it is time to hire, and how to hire and run the role remotely.

Key Takeaways

A QA tester designs test cases, runs them, reports bugs with reproduction steps, and retests fixes before each release.
Manual testers probe the product and judge behavior like a user; automation testers write code that repeats checks on every release. Most small teams need manual first.
The United States Bureau of Labor Statistics reports a median annual wage of 102,610 USD for software QA analysts and testers in May 2024.
Two signals say it is time to hire: escaped bugs, meaning bugs customers report after release, keep rising, and releases are slowing down because developers do their own regression testing.
Testing works well remotely because it already happens in shared tools: the test environment, the bug tracker and the release checklist.

What Does a QA Tester Do?

A QA tester is a software professional who verifies that a product works as intended before it reaches customers. The job combines reading requirements, designing tests, running them, documenting bugs and confirming fixes.

The Bureau of Labor Statistics groups the role with software developers in its Occupational Outlook Handbook and describes the work as developing and running tests to find software problems and their causes (U.S. Bureau of Labor Statistics, 2025). In a small company, that translates into a person whose whole day is finding what is broken before a customer does.

A good tester is not the person who clicks around until something fails. A good tester reads the ticket, writes down what correct behavior looks like, tests the edges, and writes a bug report a developer can act on without a follow up question.

What Does a QA Tester Do Day to Day?

A QA tester's day follows the release cycle: new features coming in, fixes going back out, and a regression check before anything ships.

Review new tickets and write test cases that describe expected behavior, edge cases and error states.
Test new features in a staging environment as developers finish them.
Report bugs with a title, steps to reproduce, expected result, actual result, environment, and a screenshot or recording.
Retest fixed bugs and close them only when the fix is confirmed.
Run regression tests before each release to make sure new code did not break old features.
Triage customer reported bugs with support, reproduce them, and turn them into clear tickets.
Keep the test case library current so the next release starts from a complete checklist.

Step six is where a tester pays off fastest in a SaaS company. Support teams often forward vague customer complaints. A tester who reproduces the bug and writes a clean ticket can save a developer an afternoon. Our guide on scaling SaaS customer support with a remote L1 team covers the support side of that handoff.

Manual vs Automated Testing: Which Does Your Team Need?

Manual testing means a person runs the tests and judges the result. Automated testing means code runs predefined checks on every build. Most small teams need manual testing first, then automate the checks that repeat on every release.

Factor	Manual tester	Automation tester	Winner
New features changing every week	Adapts immediately	Scripts break and need rewriting	Manual
Regression checks on stable features	Slow and repetitive	Fast and repeatable on every build	Automation
Usability and confusing flows	Notices what feels wrong	Checks only what it was told to check	Manual
Frequent releases	Becomes a bottleneck at high volume	Keeps pace with daily releases	Automation
Cost and ramp time	Lower, productive within weeks	Higher, needs coding skills and setup	Manual

A practical path for a small product team: hire a manual tester who can document test cases well, then add automation for the regression suite once the product stops changing shape every week. Some testers do both, and those profiles cost more.

When Does Your Product Need a Dedicated QA Tester?

Your product needs a dedicated QA tester when two numbers move in the wrong direction at the same time: escaped bugs go up and release frequency goes down. Either one alone can have other causes. Both together usually mean testing has become nobody's job.

Escaped bugs are bugs found by customers after a release. Count them per release from your support tickets. If the count rises for several releases in a row, the team is shipping faster than it is checking.

Release frequency is how often you ship to production. If releases are slipping because developers spend days clicking through old features before every deploy, you are paying developer rates for regression testing.

Customers report the same kind of bug more than once.
Developers say "it worked on my machine" about bugs support escalates.
Releases wait on a manual check that only one person knows how to run.
Your largest customers mention bugs in renewal conversations.

Two or more of those signals mean the testing work already exists in your company. It is being done badly, late, or by your most expensive people.

How Much Does a QA Tester Cost?

In the United States, the median annual wage for software QA analysts and testers was 102,610 USD in May 2024, according to the Bureau of Labor Statistics (U.S. Bureau of Labor Statistics, 2025). Add payroll taxes, benefits and equipment, and the full cost of a local hire sits well above that figure.

Seniority and specialty move the number. Automation skills, performance testing and security testing all cost more than manual functional testing. Contractors and agencies bill by the hour, which works for a launch but gets expensive as an ongoing seat.

A full time remote tester in Latin America usually costs a fraction of a United States salary for comparable experience, and works overlapping hours with your developers. Exact cost depends on manual versus automation skills and years of experience, so it is worth scoping the role before comparing quotes.

How Do You Hire and Run a Remote QA Tester?

Hire a remote QA tester the way you would hire any tester: give them a real build, a real ticket and an hour, and read the bug reports they produce. Then run the role with written test cases, a shared bug tracker and a clear release checklist.

Hiring a tester should follow the same logic the job itself follows. Patrick McCuller frames technical hiring around taking an engineering approach, relying on evidence, and treating candidates as customers (McCuller, 2013). A scored build with known bugs produces that evidence; a conversation about testing philosophy does not. Scott Wintrip calls the same step an experiential interview, one that gives proof a candidate either fits the work or does not (Wintrip, 2017).

Define what the tester owns: new feature testing, regression before release, customer bug reproduction, or all three.
Run a practical test. Give candidates a staging build with known bugs and ask for written reports. Clear reproduction steps matter more than the number of bugs found.
Check written English. A bug report a developer cannot understand costs more than no bug report.
Give access to staging, the bug tracker and the release calendar on day one, and nothing else.
Set a weekly review of escaped bugs and test coverage with the engineering lead.

Time zone overlap matters for testing because bugs found at 4pm need a developer who is still online. Our guide on Latin America time zones against United States business hours shows the overlap by country.

Remote Latinos places vetted technical professionals from Latin America, including testers. You can hire a vetted remote QA tester, review the roles most commonly staffed remotely, or read our guide on how to hire remote developers if you are building the wider engineering team.

Conclusion

A QA tester finds what is broken before your customers do: writing test cases, running them, reporting bugs clearly and confirming fixes before release. Start with manual testing, automate the regression checks that repeat, and hire when escaped bugs rise while releases slow down.

Judge candidates by the bug reports they write, not by the tools on their résumé. Give the role clear ownership and a weekly number to watch.

Frequently Asked Questions

What does a QA tester do?

A QA tester verifies that software works as intended before release. They write test cases from requirements, test new features, report bugs with steps to reproduce them, retest fixes, and run regression checks so new code does not break existing features.

What does a manual QA tester do?

A manual QA tester runs tests by hand, using the product the way a customer would. They follow written test cases, try edge cases nobody planned for, judge whether behavior makes sense, and document every bug clearly enough for a developer to fix it without asking questions.

What does a software QA tester do?

A software QA tester checks applications against their requirements before customers use them. The work includes test planning, functional testing, regression testing, bug reporting and fix verification, usually inside a staging environment and a shared bug tracker.

What does a QA test engineer do?

A QA test engineer usually writes automated tests in code, builds the test framework, and connects it to the release pipeline so checks run on every build. The title often signals automation skills on top of the manual testing a QA tester does.
