Company Description

Claros Technologies is a venture-backed deep-tech company committed to solving the global challenge of eliminating PFAS from the environment. PFAS remediation is rapidly evolving into a multi-billion-dollar global market and is at the forefront of regulatory action across the U.S., Europe, and Asia. Our patented and scalable destruction technology has been proven to eliminate 99.99% of PFAS in customer samples—without creating harmful byproducts.

We are a diverse team of scientists, business builders, and impact-driven leaders dedicated to solving critical environmental problems. In early 2024, Claros closed a $20 million financing round led by top environmental venture capital firms, positioning us to scale commercial adoption and expand globally.

If you're a mission-driven and highly motivated Scientist III, join us in addressing one of the greatest environmental challenges of our time.
