The role

Mariana Minerals is hiring a Regional Permitting and Compliance Environmental Engineer to own permitting execution and compliance implementation across our U.S. mining, processing, and refining project sites. Reporting to the Global Environmental Permitting Lead, you will manage the full permitting and compliance lifecycle for assigned projects — from early project definition (FEL 1–3) through detailed design, construction, commissioning, and ongoing operations — serving as a primary point of contact with federal, state, and local agencies.

In the near term, this is a global, portfolio-wide function: you will carry permitting and compliance responsibility across Mariana's full U.S. project portfolio rather than a single fixed territory. As the portfolio expands, the role is expected to transition into ownership of a defined region, with additional hires added to cover other regions over time — so this position is a foundational build for what will become the regional structure.
