You could also try to hit up the Robocat guys (http://robocatapps.com/) and ask if they know someone in the community who have any open positions.
I don't know how well they're doing, but Planely (http://www.planely.com/) offer visas for employees, and I imagine they'd love to have you there.
Airbnb also have a Copenhagen office, and while they don't explicitly have an open position, I imagine they'd love to make an exception for you: http://www.airbnb.com/jobs/locations/copenhagen-denmark.
I have no idea how getting a cool developer gig in Copenhagen works, but you could do worse than those suggestions.
EDIT: Oh, right, there is also the newly re-released Django People: https://people.djangoproject.com/dk/. Check out the profiles and see if any companies and openings show up.
EDIT2: You could also try setting up a profile on http://angel.co aimed specifically at Copenhagen.
EDIT3: You could also check out LinkedIn and Quora. I doubt they'll get you anywhere, but it doesn't hurt to try.
