Hi, You will need to find a company which will sponsor your residence permit application. The company will need to prove that no EU or Swiss citizen can do the job which you will be doing (assuming you are a non-EU citizen). This doesn't seem to be too difficult though. I just received my residence permit to work as an Electrical Engineer. I just finished my M.Sc. degree in Electrical Engineering and only have about 6 months of experience. The whole process from original application to approval took about only 2.5 weeks. I have written a little bit about my experience. You can check it out at:

Good Luck!
