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—producing the resources required to power the technology of today and tomorrow.

Why Phoenix Tailings

At Phoenix, we’re building more than technology—we’re building the future supply chain for critical and rare earth metals. This work matters. It demands urgency, rigor, and creativity. You’ll join a team that values ownership, technical excellence, and the courage to challenge legacy approaches to mining and metals production.

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 Process Engineer with deep experience scaling mining or metals processing operations from pilot or early commercial stages into reliable, high-throughput systems. In this role, you will own core process design decisions that directly impact recovery, throughput, operating cost, and system reliability. Your work will be foundational to Phoenix Tailings’ transition from development-stage technology to full commercial operations—helping secure a domestic, clean supply of critical metals.
