About Phoenix Tailings

Phoenix Tailings is a rapidly growing clean mining and metals production startup dedicated to sustainable and economic critical metals production. Our mission is to be the world’s first fully clean mining and metals production company—unlocking the materials required for aerospace, defense, and advanced manufacturing while eliminating waste and emissions from mining.

Why Phoenix Tailings

At Phoenix, we believe nothing great is ever accomplished alone—or without the passion of people who push and motivate one another. You’ll be joining a team building the foundational infrastructure for the modern world, developing entirely new ways to produce rare earth and critical metals domestically, cleanly, and at scale.

Our Values:

● You are only crazy if you are wrong, it’s ok to be wrong

● Lead with Compassion

● Be Resourceful

● Listen

● Hustle

Who We Are Looking For:

Phoenix Tailings is looking for a Senior R&D Scientist to advance high-temperature metallurgical processes and high-vacuum systems that enable cleaner, more efficient production of critical metals. This role is for a hands-on scientist who can design experiments, operate complex thermal and vacuum equipment, and translate process data into meaningful improvements. You will help develop the core technology Phoenix Tailings is building to produce the metals that power the modern world.
