If you are currently looking for a job in IT (Linux related) and would like a help in writing your application letter, I found a little “how to” on a Linux related site that describes “How to craft a Killer Cover Letter for Linux Jobs”.](https://www.linux.com/learn/tutorials/532682:how-to-craft-a-killer-cover-letter-for-linux-jobs)
I do not know how professional or efficient the how-to is, still I know that every hint helps when searching, so I do put it here as a link for who is “in need”. Just in case: good luck.
So I don’t really know anything about the place, but if your looking for a job in Linux, I see these signs all around Austin these days where they are looking for people that know Linux. Perhaps you can use that great cover letter that stakanov has mentioned.
