PHNX Materials
PHNX Materials is seeking a Mechanical Design Engineer to convert process concepts into buildable hardware during the scale-up phase. The role involves creating detailed 3D models, drawings, and specifications for equipment lines, including vessels, skids, and piping. The engineer will collaborate with process engineering, R&D, and external partners to ensure successful fabrication, installation, and commissioning.
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.
