Trying to get connection in the company ……

Hello Tech Republic
I post a question that maybe you can help me with. I have posted something similar but it was more of a general question, I have something more specific Where I am currently working they have job posting and I know that I don?t have the experience that is needed to really complete the job . May have knowledge of what has to be done but not enough to jump in the position and be an effective player. I want to let them know about me and my skills and maybe consider me at a later time. How should I go about trying to my name in the IT Department? Any suggestions?
