About the Role

Our Technology and R&D organization - chemistry, hydrometallurgy, separations, analytical science, and the broader technology function - is led by our CTO. We're hiring a Chief of Staff to be his right hand: owning project management across R&D and Technology, keeping the team aligned on priorities, and serving as the connective tissue between the science and the business. This is a dedicated role for the CTO's organization - distinct from our company-wide Chief of Staff function, which supports the CEO.

This is a technical program management and organizational role, not a bench-science role. You'll need enough fluency in the chemistry to know how the pieces fit together - where a delay in one workstream blocks another, and where a business priority should change what R&D works on next.
