I meant more that I haven't really seen any open positions anywhere about positions like that, so I've thought it's more about who you know than what you know.

I meant more that I haven't really seen any open positions anywhere about positions like that, so I've thought it's more about who you know than what you know. I might be wrong though. Regarding skillset I pretty much have all of those. I have mostly thought that particular set of skills is not _that_ much needed (compared to <nodejs/C#/java/whatnot>) Thanks about those links. While I'm well acquainted with iquilezles the other two were new for me. The first link was especially interesting as I'm quite interesting in OpenCL raytracing, so that will save me a lot of research time in the near future, especially about the data structure selection. Interestingly with OpenCL 2.0 and devices that have shared memory anything that is fast to build on CPU and slow/open area of research on GPU can be pretty much ignored as the bottleneck between the two devices do not exist anymore.
