SDET career growth

Hi Team,

I started as SDET in 2017. I got one promo while I was at my first job in 2020. Then I left in the latter half 2021. I love my job and what I do as it comes with less pressure of deadlines but every now and then I read that the SDET is a dead-end career. If anyone of you have started out in a similar role, what does your career trajectory look like? What should be my career path going forward?
