What is the future of safety test engineer? Is there a development prospect?

Today I saw this question again, I'd better give you a little more. Are you just graduated? If you want to accumulate some experience, it is possible, testing is the foundation, after that you can turn to project engineers. After that, you can switch to something else. Depending on what your interests are, if you like this line of work, you can keep doing it and open your own company, if you don't like it, related industries are also possible, such as design and development engineers, etc. I have a colleague who has changed his job to a project engineer. I have a colleague is also turned to go.
