The Center for Climate Systems Modeling (C2SM) is one of ETH’s competence centers and joint venture between ETH Zurich, MeteoSwiss, Empa, WSL, and Agroscope. One central focus of C2SM consists of providing technical programming support to the members groups in the area of regional weather and climate modelling. In particular, C2SM, in close collaboration with ETH Zurich and MeteoSwiss, is involved in the further development, maintenance, and hosting of the regional weather and climate model COSMO ( C2SM supports both the traditional version running on central processing units (CPUs), as well as the version running on graphical processor units (GPUs).
Scientific Programmer (50-100%)
C2SM is seeking to appoint a Scientific Programmer to extend their service in regional climate modelling (RCM). In particular, she/he will: support short-term requests from the C2SM regional climate modelling community on a daily basis. These requests usually comprise technical problems with running, compiling, and debugging code, including issues with the GPU enabled version of COSMO, which is more complex than the CPU version; take over longer term technical projects per year assigned from individual C2SM member groups focused on technical model development; co-administrate the COSMO support software, which is used by the international weather and climate model consortia COSMO and ICON. This task is to be shared with the principle C2SM RCM programmer.
You have an MSc or PhD in Computer Science, Physics, Atmospheric Science or related field. You have relevant experience with weather and climate models and outstanding programming skills in Fortran and possibly C/C++ in a Unix environment (other languages like Python etc. is a plus). Experience in high-performance computing, in particular in GPU programming (CUDA, OpenACC), will be considered an advantage. To round off your profile, you are a team- and service-oriented and goal-driven individual enjoying working in a diverse working environment and interested in providing support to students and scientists within a large community.

We offer an engaging position which provides the opportunity to work on technically developing scientific software, to collaborate with internationally renowned research groups and supercomputing centres, and to be part of a motivated team. The position is available from October 2019 (or as soon as possible thereafter). Initial appointment is until December 2020.
We look forward to receiving your online application including a letter of interest, a CV, and the names and contact information of 2–3 references via the following link: Please apply exclusively via the online application portal. Applications sent by e-mail or post will not be considered. Applications must be submitted by 31 July 2019 the latest.
