Duration: 2+ years,

Job location: Waldeck Pyrmonthlaan 14, 6865HH Doorwerth

Bruto monthly salary: starting at €3,483 gross per month (with possible bonuses)

Employer: OpenGeoHub foundation

Job Description OpenGeoHub foundation is a not-for-profit research foundation with headquarters at Doorwerth (half way between Wageningen and Arnhem), the Netherlands. We aim to become world experts in producing global and regional spatial predictions of soil, vegetation and climatic variables. For this, we use high performance computing, Copernicus Sentinel data, and state-of-the-art machine learning and modeling.

OpenGeoHub foundation is looking for a soil-hydrology data expert with soil knowledge of pedometrics methods. You would primarily contribute to the high profile Horizon Europe projects AI4SoilHealth.eu , Open Earth Monitor (OEMC) , Open Geospatial Carbon Registry (OGCR) , HydroDataCube, but also actively contribute to the soildb.OpenLandMap.org and EcoDataCube.eu. You would contribute to soil data quality control, fitting pedo transfer functions (using R and/or Python), running various erosion, hydrological flow models, working with Digital relief/topographic data, spatial modeling with soil-hydrology data, doing interpretation of soil predictions including predictive soil mapping results.

OpenGeoHub would provide HPC infrastructure called EOsoilmapper (that includes own copy of Landsat, MODIS and numerous other global and regional data sets; >3PB of data running on some 50 servers) and would lead and supervise the candidate jointly with other partner organizations on the AI4SoilHealth, OEMC and OGCR projects. You would assist in developing soil-hydrology models for the purpose of soil erosion risk mapping, flood / drought risk mapping, based on the best training points with in-situ measurements.

You would also support projects that are implemented by networks of researchers outside of OpenGeoHub. OpenGeoHub works closely with IIASA (Geo-wiki.org), Utrecht University, Wageningen University (Laboratory of Geo-information Science and Remote Sensing), EURAC Research, The Woodwell Climate Research Center, Max-Planck-Institute for Biogeochemistry (Biogeochemical Integration Department), Institute for Geoinformatics (ifgi) / University of Münster, CNR IRPI, GFZ Helmholtz German Research Centre for Geosciences, GiLAB.rs, Technical University of Vienna, DLR, and many other organizations. Our clients / collaborating organizations also include: World Resources Institute, The Nature Conservancy, UNCCD, Conservation International and others.

“Soil is not just a medium for growth; it is a reservoir for water and carbon that also moderates the global climate. Healthy soil infrastructure is the hardware; our project is building software to operate the hardware.” Your profile

Minimum Requirements

• You have an MSc degree in the field of hydrology and/or agronomy and/or soil
• You have a minimum 3 years of work experience.
• You are familiar with soil laboratory data and soil laboratory procedures, soil sampling and soil in-situ measurements.
• You have minimum coding & geocomputing skills in data science programming languages such as Python, Bash, R, and/or Julia.
• You have solid knowledge of statistics / pedometrics.
• You have experience with soil laboratory methods.
• You know how to simplify code and processes and run automated software checks.
• You are fluent in English.
