Senior Soil Remediation Engineer - 100%

At CellX Biosolutions AG, an innovative ETH spin-off, we develop microbial solutions to degrade persistent environmental pollutants such as PFAS, and pesticides. Our mission is to bring the world's first commercial bacterial solution for PFAS remediation from the lab into real-world industrial application.Role OverviewWe are looking for an experienced Soil Remediation Engineer to lead the development and field application of microbial solutions for the remediation of PFAS in contaminated soils. You will design and run PFAS bioremediation projects from lab pilots to field-scale trials and full decontamination of contaminated sites and work closely with clients and regulators to deliver scalable bioremediation solutions.Key responsibilities- Lead the design and execution of lab and field-scale soil remediation projects, testing and optimizing CellX's bacterial solutions on contaminated soil matrices in the lab and on site (e.g., industrial sites, landfill soils, agricultural land)- Develop experimental and remediation strategies adapted to variable and complex soil matrices and translate client and site requirements into experimental designs, remediation strategies, and technical deliverables.- Assemble and adapt microbial consortia for biodegradation of PFAS in soil- Apply targeted molecular and sequencing approaches (e.g., 16S rRNA, qPCR, WGS) to characterize soil microbial communities and track key degraders- Set up, operate, and optimize ex-situ and in-situ bioremediation systems (e.g., biopiles, in situ bioremediation slurry-phase bioreactors)- Monitor and control key process parameters (moisture, pH, oxygen, temperature, nutrient availability, contaminant levels)- Plan and interpret analytics (e.g., LC-MS/MS) in collaboration with our analytics unit to track degradation performance- Support permitting, reporting, and regulatory interactions related to contaminated site remediation- Collaborate closely with internal teams (R&D, analytics) and external partners to advance and scale solutionsYour profileRequired qualifications- MSc or PhD in Environmental Sciences, Soil Science, Microbiology, Bio-chemical Engineering, or a related field, with several years (5+) of industry experience in the remediation of xenobiotics in soil - Strong, hands-on industry track record in soil bioremediation, ideally including project management of full scale remediation projects - Proven experience in the biodegradation/biotransformation of xenobiotics (e.g., PFAS,...
