Engineer in isotope laboratory (f/m/d)

The Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) is the largest German centre for ecosystem research on inland waters. It is an institute of the Forschungsverbund Berlin e.V., which is responsible for eight non-university scientific research institutes in Berlin and is financed by the Federal Republic of Germany and the community of the Länder. The research institutes are members of the Leibniz Association.

State-of-the-art and sustainable analytics for stable isotopes in environmental samples is central to the ecohydrological research orientation of the IGB at the interface of ecohydrology, biogeochemistry and biology. For this purpose, the IGB maintains a modern isotope laboratory (based in Department Ecohydrology and Biogeochemistry). The operation and maintenance of the complex analytical equipment requires a suitably experienced and trained laboratory engineer (f/m/d) starting 1 March 2023.

Your tasks

  • Independent supervision of the specialised analytical equipment in the isotope laboratory of the IGB (especially laser spectroscopic methods, isotope ratio mass spectroscopy)
  • Independent supervision of in-situ isotope analysers
  • Independent analysis of environmental samples for their isotope signatures (solid-liquid-gas samples) using CRDS, ICOS, IRMS (see above)
  • Sampling in the field, sample preparation in the laboratory
  • Detailed sample post-processing and data preparation of isotope data
  • Maintenance of equipment
  • Collaboration in research and development of new methods
  • Contribution to scientific publications
  • Guidance and support of scientific staff and students in their work in the isotope laboratory

Your profile

  • Relevant university or technical college education
  • Strong knowledge and experience in the analysis of stable isotopes in water and gas samples using laser spectroscopic methods (cavity ringdown spectroscopy, CRDS, and off-axis integrated cavity output spectroscopy, OA-ICOS) as well as environmental and tissue samples using classical isotope ratio mass spectroscopy (GC-, EA-IRMS)
  • Ability to work independently with complex analytical equipment and interest in hydrological and ecological research topics
  • Very good knowledge of technical contexts, very good IT skills and confident use of standard software applications
  • Very good knowledge of statistics and data quality management
  • Very good written and spoken English
  • Ability to communicate and work in a team

"Research for the future of our freshwaters" is the mission of the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB). The IGB is Germany's largest and one of the leading international research centres for freshwaters. We seek to understand the fundamental processes governing freshwaters and their communities. Our research findings help to tackle global environmental changes and to develop measures for sustainable water management. The IGB is a diverse and inspiring place to work and conduct research. We promote individual development at every career level and stand for lively exchange and cooperation. With more than 350 employees and guests from all over the world, we conduct research at five locations in Berlin and at Lake Stechlin (Brandenburg). IGB closely collaborates with numerous national and international universities and other partners in science and society and is a member of the Leibniz Association, which connects 96 independent public research institutes in Germany.
