Who is a tester (QA engineer)?
A tester is a specialist who checks websites, applications, and programs and evaluates LLM models for errors and inaccuracies. They record any defects in a report for the developers so they can fix them and release a high-quality product.
Find out if being a tester is right for you
Decent pay
The starting salary for a Junior QA is around €2000. After three years, it can rise to €3,000 or more. With experience, you can explore related fields with even higher pay.
Easy start
You can get into testing from any profession. No programming knowledge or perfect English required. Age is not a barrier. The main thing is to be good with computers.
Remote format
Remote work is normal for QA engineers. Yes, yes, no traffic jams, no dress code, and no time wasted on commuting. In your own home, in your favorite chair with a cup of tea and a cat on your lap.
Demand
The number of websites and apps is constantly growing, and all of them need to be tested. Even artificial intelligence is not a competitor to QA engineers, but their client! So there’s plenty of work for the mind!
