Hey Eddie! Yes, it's always an issue to find a job with a different job title than your current position, such as from QA Engineer to Senior Frontend Developer.
But unemployed junior devs tend to get stuck at the step of "I need a job to move any further," while early-career devs who have 1-2+ years of work experience doing QA can and do eventually move out of QA.
The thing to remember is that every remote job will get 1,000 applicants in its first week, so either apply to in-person or hybrid roles or recalibrate your search expectations (applying to 10 jobs per workday over lunch is 2500 job applications in a year).
