Chief of Staff - Operations Phoenix Tailings About Phoenix Tailings Phoenix Tailings is a U.S.-based rare earth metals company building the most technologically advanced rare earth manufacturing platform in the world. The company develops and deploys breakthrough technologies across chemistry, industrial hardware, and digital infrastructure to produce rare earth metals and critical materials domestically at lower cost, higher efficiency, and greater scale. We operate a fully integrated rare earth production platform spanning extraction, separation, refining, and metallization with a zero waste and zero emissions philosophy. The company is focused on restoring America's leadership in critical minerals and building the foundation for a secure domestic supply chain powering defense, energy, robotics, aerospace, and advanced manufacturing. 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 About the Role Phoenix Tailings is looking for a Chief of Staff • Operations to own critical programs across the Operations organization and build the program management infrastructure Phoenix needs to scale. As Phoenix Tailings grows from an early-stage technology company into a world class critical metals producer, the complexity of our government awards, commercial programs, supply chain, procurement, compliance, and company-wide operational initiatives is increasing rapidly. This role will turn those commitments into clear, executable programs by establishing the schedules, ownership, operating cadences, program controls, reporting structures, and accountability mechanisms needed to keep complex initiatives moving forward. You will directly own high-priority programs while also helping build the systems Phoenix uses to execute across the COO organization. We are looking for someone who can bring structure to ambiguity without slowing the organization down. You should be comfortable translating broad objectives into workstreams, milestones, dependencies, decisions, and measurable outcomes, while driving accountability across senior stakeholders and multiple functions. This is a builder role, not an established PMO to inherit. You will have significant ownership in defining how program management operates as Phoenix grows, while helping create the execution infrastructure that enables the company to move faster, deliver on increasingly complex commitments, and scale the production of critical metals needed to power the modern world.
