About PHNX Materials

PHNX Materials refines coal ash waste into critical products. Our proprietary technology extracts titanium, alumina and rare-earth elements from ash while selling the residual feed as a cement substitute (SCM). Our cost-effective, scalable technology delivers a triple win: securing domestic critical mineral supply chains, helping power producers manage coal ash liabilities, and providing concrete companies a cheaper, greener alternative to cement. Founded by Stanford, McKinsey, and Tesla alumni, PHNX is on a mission to mine this abundant domestic natural resource. We are looking for builders, thinkers, and doers to help us scale from pilot to production.

This is the first business hire at PHNX Materials. You will work directly with and report to the CEO, and you will be embedded with the team on day-to-day operations.
