Full-time
Princeton Critical Minerals (PURELi)
About the Company
Princeton Critical Minerals Inc (PCM) is a Princeton University spinout developing breakthrough technologies to enable sustainable extraction of lithium and other critical minerals. Our mission is to increase global mineral supply while minimizing water use, energy consumption, and environmental impact. We operate at the intersection of materials science, chemical engineering, and field-scale deployment, with active pilot programs in the U.S. and internationally.
About the role
We’re hiring a Chemical Engineer II to test and maintain our reactors, analyze water composition, and help run our lab. You’ll work daily with mechanical, electrical, and chemical engineers in a small, hands-on team that supports pilot field tests and deployment.
What you will do
- Run reactor tests on customer samples, collect performance data, and write test reports.
- Analyze water composition (e.g., pH, conductivity, dissolved solids, and ions).
- Support field pilots and deployments.
- Maintain reactors in the lab and on site, and work with our electrical engineer to improve sensors and automated controls.
- Help manage daily lab operations: safety, instrument calibration, user training, chemical inventory and storage, and waste disposal.
Required
- BS or MS in Chemical Engineering or a related field, with 2+ years of professional experience.
- Hands-on lab skills, including water analysis methods and instruments.
- Ownership mindset: you take initiative, communicate clearly, and work well independently in a small team.
Preferred
- Experience working within structured lab, safety, and quality systems.
- Hands-on experience with reactor design, assembly, and operation, and/or water treatment or process testing.
PCM Inc. is an equal opportunity employer committed to building a diverse and inclusive team.
