The posting, as Alta Resource Technologies, Inc. wrote it

About Us
Alta is reinventing how the world sources critical minerals — using protein-based chemistry to extract rare earth elements and other essential materials from challenging feedstocks with unmatched selectivity. By dramatically reducing the cost and environmental impact of mineral separation, Alta is making it possible to unlock new sources of supply for 21st-century technologies. As global demand accelerates, securing these materials has become one of the most urgent challenges facing U.S. competitiveness and national security. Backed by top investors and government partners, Alta is growing fast and hiring mission-driven scientists and engineers to help us scale our platform and transform the future of mining.

How we work

Speed is part of our DNA. We’re building first-of-a-kind technology and facilities, which means the path isn’t always mapped. We’re comfortable with ambiguity: making sound, timely decisions guided by clear priorities, adapting quickly as we learn, and keeping a relentless focus on moving our business forward. We commit to fixed milestones on compressed timelines and hold ourselves accountable without compromising on safety or rigor.
