Take it mate, sounds like an interesting job that could have good prospects. Possibly less exposure to harmful materials/chemicals etc. Maybe friendlier shift patterns?
I'm ready to put my B1 license application in now and I'm at the point of wishing I'd spent my time studying to get into another field.
Similar to yourself I've lost a lot of enthusiasm for aviation over recent years and I think that passion for aviation is definitely a prerequisite for job enjoyment.
Hope whatever choice you make works out for yourself. 👍
