Scientific programmer position (Z2a)

Computing Services

This scientific programmer position contributes to project Z2 "Computing services".

Primary supervisor: Dr. Robert Redl
Other project leaders: Prof. Dr. George Craig, Dr. Christian Keil, Dr. Marc Rautenhaus and Prof. Dr. Andre Brinkmann

The Theoretical Meteorology group at the Meteorological Institute (MIM) at the LMU Munich offers a part-time postdoc position within Phase 2 of the collaborative research center "Waves to Weather" (W2W). The Theoretical Meteorology group at MIM has a strong focus on predictability of weather and has established a leading international reputation in atmospheric predictability, stochastic parameterization and data assimilation. As one of Europe’s leading research universities, Ludwig-Maximilians-Universität (LMU) in Munich is committed to the highest international standards of excellence in research and teaching. Building on its more than 500-year-long tradition, it offers a broad spectrum that covers all areas of knowledge within its 18 Faculties, ranging from the humanities, law, economics and social sciences, to medicine and the natural sciences.

The IT infrastructure project Z2 is responsible for providing the essential support, expertise and facilities for computing-based research in W2W. Huge requirements of the research projects in computing and data sharing are met by a twofold approach consisting of a service and a research component. The service component addresses requirements for a central code repository and collaboration platform, internal and external web pages, and a data management strategy to enable storage and transfer of huge amounts of data, a strategy to archive data in local and community accessible archives to ensure the reproducibility of results, as well as support for visualization. Training events and workshops are also part of the support strategy. To meet these requirements we will take a distributed approach, with staff and hardware located at each of the three W2W locations (Munich, Karlsruhe, Mainz). An additional Postdoc positions is open in Hamburg.

The research component has two parts. The successful candidate will investigate the applicability of newly available Python libraries that support code parallelization, as well as lossy compression algorithms to greatly reduce data volumes, to W2W diagnostic tools. If these methods live up to their promise, it will have a direct impact on many W2W research projects by enabling them to exploit substantially larger data sets. The second research project, to be carried out by a PhD student in Mainz, will explore the use of Algorithmic Differentiation (AD) on meteorological codes, with initial emphasis on cloud models.

The ideal candidate holds a PhD in Informatics or natural science and is enthusiastic about programming in Python. Knowledge of at least one compiled programming language including parallelization and standard build tools are also required. The offered position contains not only pure programming activity but is located at the interface between IT infrastructure, software development, and support for others in developing, debugging, and optimizing software. Thus, besides programming knowledge and very good communication skills in English, knowledge of debugging and profiling tools as well as familiarity with Linux at system level and especially with (parallel) file systems is advantageous. The work is focused on numerical weather prediction, which means experience with meteorological models (written in FORTRAN) and data formats is an advantage, the same also applies to data compression formats and handling of very big data. Since work is done in a team, it is not expected to be an expert in all fields mentioned, but it is to be motivated to learn about new topics.

The position is remunerated according to TV-L E13 (50%, part-time), it is offered for 4 years and should start as soon as possible. Applicants are asked to specify their desired starting date and to give the contact details of two academic referees.

W2W features an innovative program for the development of early career researchers based on self-government. In addition to self-organized activities such as workshops, trainings and a guest program, the successful candidate will have the opportunity, if desired, to pursue an international research visit of at least one week. The consortium
conducts an ambitious program to gradually enhance gender equality on all career levels within the academic fields combined in W2W.

LMU is an equal opportunity employer. Women are especially encouraged to apply. Applicants with disabilities will be preferentially considered if equally qualified. The successful candidate will work in the city center on Munich and will have access to extensive training and career development activities offered by the LMU.
