Ask HN: How to best advertisize my career aspirations?

I will be completing 13 years as a software professional, and my quest for that “dream” job still continues. I am not unhappy with my current job, I am quite content in what I am doing. I have been receiving very good appraisal ratings in my current company, have been promoted recently, and I gel very well with my teammates. The work is quite interesting, and apart from the occasional management created turbulence, life is quite smooth. However, I want to achieve more. I am absolutely passionate about coding, love solving tough problems and want to keep learning new technologies. Developing a disruptive technology, working in path breaking research teams, working on developing of new standards or being part of a kick-ass start-up, those are some jobs that would be my “dream”. So how I go about advertising my career aspirations ? How do I reach out to people who can help me reach my dream?
