Technician in Biogeosciences 50% (f/m/d)

You will work within the recently funded SNSF project FIRE ("Fire Impacts on the Response of terrestrial Ecosystems"). This project investigates how wildfires affect carbon cycling and transit times at the landscape scale, particularly in the deeper unsaturated zone and in groundwater, and over longer periods of time. You will be part of an interdisciplinary team of collaborators based in Switzerland and the USA, and support the team in conducting geochemical analysis (particularly radiocarbon) on environmental samples from recently burned landscapes in the USA. Your main tasks will involve preparation of a range of sample types (gaseous, aqueous, and solid) for stable carbon isotope and radiocarbon analysis. This will be done in collaboration with our partners at the Laboratory for Beam Physics at ETH Zurich, where you will also frequently work. Processing of samples for other types of analysis, e.g., major ion concentrations, general chemistry, will also be part of your duties. You will support and train a PhD candidate and guests from our partner universities in the USA in laboratory procedures. Moreover, you will also assist the team with administrative and logistical duties, e.g., the shipping of samples and materials to and from field sites in the USA.

You preferably hold a Master's degree in environmental or earth sciences or related disciplines, and have demonstrated experience with mass spectrometric methods for geochemical analysis and/or radiocarbon methods. You are familiar with laboratory work, enjoy contributing to methodological advancements, and are interested in interdisciplinary and international research. You are able to work independently, are structured and accurate, communicative and team-oriented. You have very good written and spoken English language skills. You will be part of a vibrant research group and an international team of leading researchers in biogeosciences, paleoclimatology, and terrestrial geochemistry. The position is based at WSL and initially fixed to two years with the option for prolongation for- additional two years.

Please send your complete application to Pe, Human Resources WSL, by uploading the requested documents through our webpage. Review of the applications will begin on October 22, 2026\.
