Mining Engineering Manager
About The Position
Mariana Minerals is seeking a Mining Engineering Manager to lead mine project development across early and mid-stage studies, from concept through feasibility and execution. This role is responsible for integrating geology, mine planning, geotechnical analysis, infrastructure, and supporting disciplines into coherent, executable mine development strategies. In this role, you will act as the technical owner for mine project definition—ensuring that geological understanding, mine designs, schedules, infrastructure concepts, and risk assessments are aligned and developed to the appropriate level of maturity for each project stage. You will coordinate multidisciplinary teams, manage technical trade-offs, and support decision-making related to project advancement, sequencing, and capital allocation. This is a senior technical management role focused on integration, rigor, and project readiness rather than day-to-day operations.
Requirements
- Bachelor’s degree in Mining Engineering
- 10+ years of progressive mining engineering experience across both open pit and underground operations
- Demonstrated experience leading or integrating multidisciplinary mine development studies
- Strong understanding of geology, mine planning, geotechnical design, and mine infrastructure development
- Experience acting as or supporting QP/RP for NI 43-101, SK-1300, and/or JORC-compliant studies
- Ability to balance technical depth with project-level integration and decision-making
- Strong communication skills and comfort leading cross-functional technical teams
- Professional Engineer (P.Eng / P.E.) or equivalent
Nice To Haves
- Experience with greenfield or early-stage mine development projects
- Experience managing external consultants and study budgets
Responsibilities
- Lead mine project development activities from early concept through pre-feasibility and feasibility stages
- Define project scope, study objectives, and technical deliverables for mine development work
- Ensure mine projects are developed with clear assumptions, consistent methodologies, and appropriate levels of technical maturity
- Coordinate and integrate inputs from geology, mine planning, geotechnical, hydrogeological, infrastructure, and processing teams
- Ensure alignment between resource models, mine designs, schedules, infrastructure concepts, and cost estimates
- Act as a technical bridge between strategic planning and execution-focused engineering teams
- Oversee development of mine layouts, sequencing strategies, and production schedules for open pit and/or underground projects
- Ensure geotechnical analyses and design criteria are appropriately applied to mine designs and infrastructure
- Guide development of mine infrastructure concepts including access, haulage, material handling, utilities, and site layout
- Identify technical risks and uncertainties across mine development disciplines and ensure they are assessed and mitigated
- Support development of risk registers, design criteria, and project readiness assessments
- Prepare and present integrated technical recommendations to support project advancement and investment decisions
- Manage work executed by external consultants, engineering firms, and technical specialists
- Serve as the primary technical interface between internal teams, consultants, and project stakeholders
- Support downstream engineering, permitting, and execution teams by ensuring a clean technical handoff
- Lead, mentor, and develop mining engineers and technical contributors across project teams
- Establish best practices and consistent standards for mine engineering, project development, and operations across the organization
- Contribute to continuous improvement of internal tools, templates, and workflows for mine studies
