What are the responsibilities and job description for the Research & Development - Part-time position at PHNX Materials?
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.
Role Summary
Be part of something extraordinary. As an R&D Intern at PHNX Materials, you will support the development and refinement of breakthrough technologies that transform industrial ash into clean, valuable products. You will work closely with engineers and scientists to conduct experiments, generate high-quality data, and help translate lab-scale insights into scalable processes.
This is a part-time in-person role (20 hours / week) ideal for a college, Master’s, or PhD student with prior laboratory experience who is highly detail oriented, safety conscious, and excited to work hands-on in an applied R&D environment.
Job
You will play a key role shaping PHNX’s technology, building a customer pipeline, and defining future engineering.
Experimental Support
PHNX Materials is proud to be an Equal Opportunity/Affirmative Action employer. We are committed to attracting and growing a diverse team—all qualified applicants will receive consideration for employment without regard to sex, gender identity, sexual orientation, race, color, religion, disability, protected Veteran status, age, or any other characteristic protected by law.
