The Helmholtz Centre for Environmental Research (UFZ) with its 1,100 employees has gained an excellent reputation as an international competence centre for environmental sciences. We are part of the largest scientific organisation in Germany, the Helmholtz Association. Our mission: Our research seeks to find a balance between social development and the long-term protection of our natural resources.

Software Engineer for open-source data analysis of cosmic-ray neutron data (f/m/x)

The job

The Helmholtz Centre for Environmental Research (UFZ) has secured 12 months funding through the Helmholtz ScienceServe call to transform the research software “Neptoon” into a multi-purpose, open-source, community-driven toolbox that enables state-of-the-art data analysis, server-based automatic data processing, and science education using cosmic-ray neutron sensing for soil moisture estimation. Join us in building sustainable research software that supports hundreds of scientists, institutional users, and students worldwide in the context of climate change, hydrology, agriculture, and space weather.

Your tasks

Software Engineering Excellence: Lead the implementation of new scientific features, comprehensive automated testing frameworks and modern CI/CD pipelines, including containerization (Docker, Apache Airflow) that scale from individual researchers to major research infrastructures.
FAIR4RS Implementation: Champion open science by implementing FAIR4RS principles including enhanced metadata management, persistent identifiers (DOIs), and standardized APIs that ensure transparent and reproducible processing.
Community Building: Travel across Helmholtz centers and to the University of Bristol to engage with the international CRNS community, and design and deliver engaging training workshops through the HIDA catalogue.
Transfer & Impact: Design intuitive interfaces (web-based GUIs, command-line tools, Docker images) and prepare the groundwork for operational deployment in monitoring networks like TERENO and eLTER.
