PHNX Materials
PHNX Materials is seeking a part-time Payroll & Office Administrator to manage payroll processing and maintain essential office operations. The role involves ensuring accurate and timely payroll submission, maintaining financial records in QuickBooks, and coordinating office services.

PHNX Materials is a clean-technology company that refines industrial waste streams — primarily landfilled coal ash — into critical materials for the semiconductor, building materials, and agriculture industries. The company extracts high-value metals and compounds including gallium, germanium, silicon, titanium, aluminum, and rare-earth elements from billions of tons of domestic industrial byproducts. PHNX aims to reduce U.S. reliance on foreign suppliers, particularly China, by reshoring domestic critical material supply chains essential to semiconductors, defense, and advanced manufacturing.
