Job Title

Software engineer (Python/Bash/DevOps): Scalable workflows for digital twins of the climate system.

Job Description

The Climate Dynamics section at the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI) in Bremerhaven, Germany, invites applications for a software engineer (Python/Bash/DevOps) for the development of scalable workflows in support of digital twins of the climate system.

You will work with leading European climate modellers, computing scientists and software engineers on developing digital twins of the climate system in support of adaptation to climate change. The Climate Adaptation Digital Twins system harnesses two kilometre-scale Earth-system models (ESMs) to Europe’s most performant computing high-performance computing systems.

You will be part of a team responsible for development and deployment of workflows, that orchestrate simulations with km-scale climate models, analysis of the data produced by those simulations and data distribution to users. The workflow will be deployed on Tier 1 European HPC systems (e.g., LUMI - the first pre-exascale supercomputer of the EuroHPC Joint Undertaking) and should be scalable, portable and fault tolerant.

This is a full-time position, limited to 20 month. It is advertised subject to approval of funding and with the possibility of extension (depending on continued funding). It is also suitable for part-time employment. The salary will be paid in accordance with the Collective Agreement for the Public Service of the Federation (Tarifvertrag des öffentlichen Dienstes, TVöD Bund), up to salary level 13. The place of employment will be Bremerhaven.

Equal opportunities are an integral part of our personnel policy. The AWI aims to increase the number of female employees and therefore strongly encourages qualified women to apply.

Disabled applicants will be given preference when equal qualifications are present.

We look forward to your application! Please submit your application by August 26th 2022, exclusively online. Reference number 22/133/D/Kli-b

A master or PhD in one or more of the following fields is required: computer science, mathematics, data sciences, physics, meteorology, oceanography, climate sciences, or related field. Demonstrated skill/proficiency in Python or any other high-level programming language and fluency in English are further requirements.

We follow good software development practices and expect candidates to have hands on experience with version control (git), writing tests, and creating documentation.

Most of the development will be done in Python and bash, but knowing other languages like R, Julia, Matlab would be beneficial.

Moreover, having one or several of the following skills would be a distinct advantage:

  • Experience with HPC systems,
  • Knowledge of *nix based systems and bash scripting,
  • Experience with CMake and Make,
  • Knowledge of workflow managers (e.g. Airflow, Prefect, Cylc, Autosubmit, ecFlow),
  • Working with containers (Docker, Singularity),
  • Knowledge of CD/CI tools, and
  • Working with complex climate models and geophysical data formats (netCDF, GRIB, zarr).
