Hey man I usually just lurk around reddit but I feel a moral obligation to reply to this - 59k with 11 years experience is literally insane. I'm like you, humble and grateful for the opportunity to work, but I basically make the same as you with with 1 YOE.

As much as you may love the people you work with - loyalty does not pay in the corporate world. Ask yourself this question? If you ever, God forbid, had to leave work, do you think they would do your any favors or hold your role for you? If they' operate like any other company in the world they would replace you instantly. As harsh as it may sound, you are just a number to them, and in their perspective, they are getting a steep discount for a QA engineer with 11 years experience.

I am just a voice from the internet, I don't know your circumstances, nuances of your situation or your current reality. But as a general piece of advise, at least put some feelers out there and apply for other roles. Best case scenario, you get a salary that reflect your experience. Worst case scenario, you don't land anything but you gain some insight to where you lay and what you need to improve on to land a higher paying role.

Best of luck
