Project Engineer, Environmental Engineer

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 Engineer, join us in addressing one of the greatest environmental challenges of our time.

The Engineer III is responsible for supporting the design, implementation, and operation of PFAS destruction systems, including pilot- and commercial-scale projects. This role is critical to project execution, equipment specification, and process development, ensuring that Claros’ UV-PFAS destruction technology meets client needs and regulatory requirements. The Engineer III works closely with Sales, Engineering and external partners to deliver safe, efficient, and high-quality solutions that enable sustainable and responsible PFAS management.

This role will be an integral leader in establishing engineering controls, systems, and documentation as Claros
