I'd argue it's not that easy to up and quit a job if you have even just one variable added to the situation such as being limited to location. Maybe remote working is the answer. Know of any great remote jobs for Grails/Java developers?
Unfortunately, I don't know of any remote Grails/Java jobs, but I do know of several openings across the US. What location are you looking for specifically? I know some recruiters that won't try to screw you over with sub-par opportunities. If you'd like, you can send me an email through the contact link on my website and we can see if there's anything that fits you.
