QA Engineer Vs. Similar Roles
| Role | Main focus | Primary metric |
|---|---|---|
| QA Engineer | Planning and running manual and automated tests across the product | Bug escape rate, test coverage |
| QA Tester | Executing test cases and reporting defects | Test cases executed, bugs found |
| SDET | Building automated test frameworks and wiring them into CI | Automation coverage, pipeline stability |
| Software Engineer | Building and maintaining software systems | Features shipped, code quality |
At smaller companies, one QA engineer often covers manual testing, test automation, and release checks. Add a dedicated SDET or test automation role as the codebase and release pace grow.

A QA engineer plans and runs manual and automated tests across the product, with a focus on how end users experience it. An SDET builds automated test frameworks, writes test code, and connects testing to CI pipelines, and often contributes to development. Smaller teams often combine the two.
US QA engineers average around $95,200 a year. Senior QA engineers in Latin America average around $55,500 a year, about 42% less, saving roughly $39,700 a year per hire.
Most searches run 21 days from kickoff to a signed offer, with 3 to 5 candidate profiles delivered in the first 10 days.
Quality assurance is a proactive process that covers the whole development cycle. Quality control is a narrower check of the finished product. Software testing is the act of running a product to find defects, and it is one part of both.
