Software Developer is on the list of so called „shortage occupation jobs“ in Austria. Therefore it is under certain circumstances possible, to receive a work permit quite easily. Please check the points calculator of the migration office if you are suitable for a work permit before applying for a job. Here you can find the link:
Please choose „skilled worker in shortage occupation“, when they ask for which visa you would like to apply. It is really important, that you have written proof for the points you get. For example, one year of working experience abroad is worth 2 points. If you have work experience of 6 years, but you only have written confirmation / references for 2 years, you can only choose 2 years.
If you have no finished studies but successfully finished one year at a university abroad, you are probably still applicable (but also this need to be proved by your university report /confirmation), if you get altogether at least 55 points.
