Students in technology (including IT) and in economics, have a look at Karriärmöjligheter för studenter inom teknik, data och ekonomi (in Swedish) where we have collected a lot of interesting possibilities for students, including trainee programs in precision medicine and in health informatics, plus master thesis applications and summer jobs/internships. Help us reach out to students around you!
Note about language: Many of the assignments (e.g. internships and trainee programs) are also meant as a potential way to recruit new permanent staff in the long run, thus applicants knowing Swedish will often be preferred since that is the working language at the hospital. We do have a lot of staff with international background, but that (now) know Swedish.
It might be possible to do e.g. a master thesis assignment in English if it is of high value to the hospital and you do have good support and supervision also from your home university.
