Expert in Aquatic Ecology, WFD, GIS and Carbon Processes; m​/f​/x

About us

e.Ray develops measurement systems, data solutions and new methods in order to understand waters better and bring them into balance in a targeted way. To that end, we combine continuous on-site measurements, satellite data, mapping and publicly available specialist data into a holistic picture of the condition of a water body.

To grow our team further, we are looking for a technically well-versed and communicative person who combines expertise in aquatic ecology with a sound understanding of geodata and the European Water Framework Directive. A further emphasis lies on the water and carbon cycle and on the question of how the impact of water-protection, renaturation and climate-protection measures can be recorded and evidenced robustly.

At the same time, you should enjoy representing e.Ray externally, building professional networks and advancing new approaches together with public authorities, associations, the scientific community and political decision-makers.

• Technical handling and assessment of running waters and lakes under the European Water Framework Directive
• Work with biological quality elements and assessment methods, in particular:
  • Macroinvertebrates and PERLODES
  • Fish fauna and fiBS
  • Macrophytes and phytobenthos, for example with PHYLIB
• Consolidation of biological, chemical-physical, hydromorphological and spatial water-body data
• Mapping and GIS-based analysis of water bodies, catchments, pressures and measures
• Preparation and interpretation of data from the portals of the German federal states, WasserBLIcK, LAWA, Hydro ATLAS, remote sensing and further public sources
• Assessment of measurement gaps and development of sound monitoring and survey concepts
• Support with WFD reports, status assessments, planning of measures and evidence of impact
• Examination of carbon processes in water bodies, floodplains, wetlands and catchments
• Contribution to the development of baseline values, carbon balances and robust evidence for the impact of renaturation, water-protection and climate-protection measures
• Linking water quality, nutrient dynamics, the carbon cycle and greenhouse-gas emissions
• Translation of technical requirements into digital maps, analyses and understandable situational pictures
• Expert representation of e.Ray towards public authorities, water associations, municipalities, ministries, research institutions and further decision-makers
• Active participation in expert committees, working groups, networks, workshops and events
• Preparation and delivery of technical presentations, project introductions and discussions with decision-makers
• Building and maintaining long‑term contacts with actors from water management, water protection, research and policy
• Recognising new projects, cooperations and points of technical connection
• Involvement in projects around water quality, water availability, climate adaptation, climate impact and nature‑based solutions

• A completed degree, for example in limnology, aquatic ecology, biology, environmental sciences, geography, geoecology, hydrology or a comparable field
• Good knowledge of the European Water Framework Directive and of its biological and ecological assessment methods
• Experience with at least one of the quality elements macroinvertebrates, fish fauna, macrophytes or phytobenthos
• Confident handling of GIS, preferably QGIS or ArcGIS
• An understanding of spatial data, water‑body networks, catchments and hydromorphological relationships
• Interest in carbon processes, greenhouse‑gas emissions and the assessment of ecological measures
• Experience with impact monitoring, carbon accounting, soil carbon, peatlands, floodplains or wetlands is particularly welcome
• The ability to classify different data sources professionally and to merge them…
