[Haskell developers are particularly encouraged to apply] Dear all, we are happy to announce that we have new openings at the PhD and PostDoc level. The Programming Language and Software Technology Group, headed by Klaus Ostermann, conducts research dedicated to developing new technologies that help to construct high-quality software in a productive way. We use and develop an exciting set of technologies involving functional, object-oriented, domain-specific and aspect-oriented programming languages, software product lines, parser technology, language-integrated queries, static and dynamic software analysis, type systems, and many other topics. For more information consult http://www.uni-marburg.de/fb12/ps/ We offer positions with a lot of freedom to choose and develop research topics, few obligations, collaboration with a very strong group of researchers, competitive salary, and opportunities to develop a strong academic career path. We expect PhD applicants to have demonstrated the potential for scientific excellence in areas related to our own research, and applicants for Postdoc positions to have published in high-quality venues related to our research domains. Knowledge of German is a plus but not required; the default communication language in our group is English. Marburg is an attractive small "student town" right in the center of Germany. We are only an hour ride away from Frankfurt Airport, which will bring you to many destinations worldwide in a single hop. To apply for a position, please send informal inquiries to Klaus Ostermann (contact data can be found on our website, or reply to this email). We are flexible with regard to the starting date, but generally the sooner the better. We are looking forward to hearing from you. Klaus Ostermann
