Mariana Minerals is a software-first, vertically integrated minerals company focused on supplying critical minerals for modern energy, AI, and defense technologies. They are reimagining the minerals supply chain through advanced software, automation, and data-driven decision-making.
You will own permitting execution and compliance implementation across Mariana's U.S. mining, processing, and refining project sites, reporting to the Global Environmental Permitting Lead. This role manages the full permitting and compliance lifecycle from early project definition (FEL 1–3) through detailed design, construction, commissioning, and ongoing operations, serving as the primary point of contact with federal, state, and local agencies.
In the near term, you will carry permitting and compliance responsibility across Mariana's full U.S. project portfolio. As the portfolio expands, the role is expected to transition into ownership of a defined region, with additional hires added to cover other regions—positioning this as a foundational build for the regional structure.
Key responsibilities include:
**Permitting Leadership:** Own and execute permitting roadmaps across federal, state, and local agencies for all project sites. Manage NEPA EA/EIS workstreams in coordination with BLM and third-party consultants from scoping through Record of Decision (ROD). Integrate permitting requirements into FEL 1–3 and detailed design, working directly with engineering teams. Serve as primary point of contact with federal agencies (BLM, USACE, EPA, USFWS) and state/local agencies (RRC, DNR/MPCA, DEQ, UDEQ/DOGM, CalEPA, and county/municipal authorities).
**Compliance Implementation:** Implement and audit Environmental Management Systems (EMS) at project sites, ensuring permit and ROD conditions are embedded in daily operations and management of change (MOC). Manage ongoing compliance obligations for air, water, stormwater, waste, and EPCRA across assigned sites. Direct environmental monitoring programs and ensure timely submission of quarterly and annual compliance reports. Oversee remediation plans and corrective actions for environmental impacts.
**Due Diligence & Sustainability Support:** Lead environmental due diligence for acquisitions, divestitures, and new project development, assessing permitting/compliance status, risk, and regulatory exposure. Contribute permitting and compliance data to corporate sustainability and ESG reporting. Identify and implement continuous-improvement opportunities and help define regional structures and staffing as the portfolio scales.
**Stakeholder Engagement:** Act as primary interface between project and site teams and internal stakeholders (process engineering, operations, legal, executive leadership). Engage external stakeholders including regulatory agencies and consultants. Prepare concise updates for the Global Environmental Permitting Lead and senior leadership on portfolio-wide status.
**Requirements:**
- Bachelor's or master's degree in Environmental Engineering, Civil/Environmental Engineering, Environmental Science, Geology, or related field
- 7+ years of U.S. environmental permitting and compliance experience in mining, energy, or large infrastructure, with demonstrated ownership of agency relationships across multiple concurrent projects
- Demonstrated familiarity with the multijurisdictional U.S. environmental regulatory framework (local, state, and federal) and ability to navigate overlapping requirements across agencies
- Direct experience managing NEPA EA/EIS processes, including coordination with BLM and multi-disciplinary consultant teams, through Record of Decision
- Working knowledge of CAA, CWA, RCRA, ESA, EPCRA, and state/local permitting and compliance programs
- Experience integrating permitting requirements into FEL 1–3 and detailed design, and implementing or auditing Environmental Management Systems (EMS)
- Strong technical writing, agency negotiation, and stakeholder-management skills
- Comfort operating in a broad, portfolio-wide role today with flexibility and interest to shift into ownership of a defined region as the portfolio grows
**Preferred Qualifications:**
- Experience with critical minerals (lithium, nickel, graphite, etc.) or refining/processing facilities
- Experience leading environmental due diligence for M&A or project development
- Familiarity with IFC/Equator Principles or corporate sustainability/ESG reporting frameworks
- Professional certifications such as PE, PG, or CEP
- Prior experience helping stand up or scale a permitting/compliance function as an organization grew
