100 % workload
Oxyle is an award-winning Swiss clean-tech startup, founded in 2020 to solve one of the most pressing environmental and public health challenges of our time. We are looking for a committed project Engineer with a background in industrial water treatment project engineering to guide our customer project engineering team.
Our mission is to restore and protect our bodies of water from PFAS, down to the last drop. PFAS, often referred to as Forever Chemicals, are a group of more than 10,000 persistent and toxic man-made substances polluting our water, soils, and food. Our breakthrough destruction technology permanently degrades challenging PFAS compounds from wastewater. No two wastewaters are alike, so our solutions aren’t either. We design complete treatment systems by integrating our core technology with tailored approaches to ensure optimal performance.
Join a purpose-driven team tackling one of the world’s most urgent environmental challenges. Shape how PFAS destruction technologies are deployed across industries — and help protect our planet, one drop at a time.
The opportunity
The Deployment Team brings Oxyle’s technology to life — turning lab innovation into real-world impact. From understanding customer challenges to designing, piloting, and scaling treatment systems on-site, the team ensures every solution performs reliably in the field.
As Project Engineer, you will be the technical lead for customer projects — from first technical contact to pilot trials and full-scale installations. You will work closely with the customer to understand their needs and objectives, plan solution validation trials, draft customized processes and technical proposals. Reporting directly to the Head of Deployment, you will collaborate closely with Engineering, R&D and Commercial teams while ensuring that every project delivers measurable impact and satisfying solutions to the customer.
Will you join us in protecting the future of our waters?
