UK national potentially looking to work in the EU but is unsure whats going to happen with brexit

Hi all,

As the title suggests I am a Uk national who is potentially looking to get a job in the software test/dev area within the EU however I’m a bit worried about what brexit would do for that once 2019 comes.

How could brexit affect a job if I was to get a role?

I’m assuming that it would be likely that I would have to get a visa/work permit in order to continue working there

Is there anything you think I should know before making a decision on this? Or Is everything too uncertain to know currently (because I currently feel like it is)
