Stockholm in summer probably is where most English-speaking tourists will be. The ice hotel also comes to mind, but that’s seasonal, and certainly not gobs of tourists there. Maybe also consider working for a caterer or party provider.

I don’t know if Sweden’s strict alcohol laws will affect you—if certification or qualifications are needed. To legally work, you must have a work permit, and to apply for a work permit, you need a job offer. Living with fiance might help under “family reunification” if you are a registered parnership—it might help you get residence permission, which will make job hunting easier from within Sweden than from outside of Sweden.

Legal work means, of course, taxes will be withheld, part of which covers your obligatory health insurance in Sweden. Swedish income taxes are some of the world’s highest. Just keeping it real if you weren’t aware or hadn’t considered work and residence permits and, of course, taxes.

I just found this page of tips for Sweden where there are some good resources. They also have a jobs in Sweden section that is fairly good and only has the English jobs and updated fairly regularly. If all this does not work, then head over to the government work site and trawl through all the listings. Hope this helps.
