Looking for a full time job in Open Source

Two years ago I was really close to canceling my studies and looking for a job instead. In the end I continued studying, passed the final exams of my Diplom (the German old-school equivalent to a Master’s degree) with excellent results and started working on my graduate thesis. Today, I am 1 1/2 months away from the submission deadline and it is clear that I will make it.

So, this time I’m serious: I’m looking for a full time employment in Open Source software development, engineering or management starting November this year. Hiring me will get you an experienced and talented hacker with a natural intuition for software architecture and aesthetics as well as a scientific and painstaking approach to software planning and implementation.

Through my work at the university and within the Xfce and Lunar Linux projects, I have gained experience in/with

  • many programming languages (including C, C++, Ruby, Python, Vala, Lua, XSLT, TeX, Java, Bash and a couple of others),
  • many frameworks (the whole GTK+/GLib stack including D-Bus, a bit of Clutter, XLib and Qt/QML, SWT/JFace, the FOX toolkit as well as web frameworks like Sinatra and Rails; some knowledge about the Linux kernel, its facilities and kernel-userspace communication mechanisms included),
  • many developer tools (GNU compilers, Autotools, VIM, NetBeans, Eclipse and others),
  • many software versioning systems (Git, Subversion, CVS and Mercurial), and
  • various areas of computer science and software engineering (complexity theory, signal processing, graph drawing, micro-controller programming and sensor-based networking, software planning, testing etc.).

I feel equally at home developing for the desktop or for the web. Granted, my main area of expertise is user interface and middleware development on Linux, which my fellow Xfce hackers and I have successfully participated in, but I’ve always found web development with Ruby to be a refreshing change.

There are many other things related to open source that I love doing. Over the past years I’ve enjoyed being able to improve the transparency of the development and release management of Xfce. Streamlining the release process and providing tools for making release management fun was an initiative I am particularly proud of. The same goes for community efforts like the Xfce Foundation, which we’ve launched in early 2011 and which I am currently heading as president.

This post is not just about the past though, it’s also about what lies ahead. Things I am particularly interested in with regards to the future include

  • mobile platforms and applications (iOS and Android are not good enough, I think we need open alternatives),
  • multi-touch interfaces on Linux (yep, this is on the way, but there still is a lot of potential work to be done, I guess),
  • cloud-based applications (I know I can store files and data on the web, but where are the mind-blowing features that go beyond availability of personal data everywhere?), and
  • environmental and power saving applications (living responsibly will become important soon enough; how can we generate awareness and support environmental causes with the help of software?).

I am excited and curious what my role will be in all this. Anway, I guess this is enough information about me for now. After all, this is no biography but a job-search post. ;)

If you read this and you happen to be Microsoft or Apple, do not even bother to send a headhunter. I prefer to work in the open and I believe in Open Source for many reasons. This ecosystem that we’ve created over the past two decades provides a great way for people from all around the world to collaborate on projects they care about, in an honest and tolerant way. I think that’s an inspirational model from which our entire society can and hopefully will benefit. Why would we want to have it any other way?

If you are a member or leader of a company dedicated to Open Source software and are interested in hiring me, please let me know. Linked below are my resumé, software projects and email address. I’m looking forward to talking to you!

Download my resumé/CV — A list of references is included. Feel free to contact them; they are aware of being listed and I’m sure they will be happy to answer any of your questions.

Final exams, diplom thesis and thunar-volman

I guess it’s time for an update.

This week I passed the last of four final exams in computer science and human-computer interaction at my university. Not only am I pleased that nine months of learning are over; I am also blessed with excellent grades. And while my understand of good grades is similar to that of money (nice to have it but nothing to focus on and/or brag with), I have to admit that this time I’m at least a little proud of myself. Five years at the university are slowly coming to an end, the first friends are leaving town and it will soon be time to take the next big step in life.

I cannot leave this city before writing another thesis, however. Thus, I am currently looking for a Diplom thesis at the university or at companies related to open source technologies. If you happen work for such a company with interesting thesis ideas or opportunities, please let me know. The thesis is supposed to take about 6 months, ideally starting early in September. After that it’s time to pack my stuff and look for an employer. I’m hoping for a position in open source software development. Areas I’m particularly interested in include Linux, mobile computing, desktop-related technologies as well as renewable energy, environment protection and open government. I’m here to make a difference.

On to something else. A few weeks ago I was offered sponsoring in order to work on thunar-volman for a few days. I accepted the offer, so for the entire next week from 2010-07-19 to 2010-07-26 (including the weekend) I’ll do some sponsored work on porting Thunar and thunar-volman to udev and GIO! The goal is to finish all major features (storage devices, cameras etc.).

Yesterday I did some warm-up hacking on tumbler to verify that if I’m still up to the task. The results: a new ffmpegthumbnailer-based video thumbnailer plugin (written by Lionel Le Folgoc), a new PDF/PostScript thumbnailer plugin based on poppler-glib and a new tumbler release (0.1.2). The master branch contains another commit adding arbitrary URI support to the PDF/PostScript thumbnailer but for that you’ll have to wait until the next release.

That’s it for now, I’ll be a lot more active next week. Take care everyone!
