• Reporting to the Chief Mine Engineer, the Senior UG Mine Engineer will lead the mine design efforts for KoBold’s Mingomba project, including pre-feasibility and feasibility engineering studies. • You will help to identify, design, and execute all mining engineering programs necessary to maximize the safety, feasibility, and value of our future mine. • In addition, you will be responsible for the strategy, implementation and execution of mine design strategies consistent with development plans and in coordination with operations teams. • You will also support all modeling work from district to mine scales in support of these goals. • You will be responsible for building and fostering a collaborative relationship to support synergies with surrounding operators. • You will join an outstanding team of geoscientists, data scientists, and software engineers. • You will be a core part of the project teams, supporting the advancement of the science and practice of exploration. • You will support the development of novel data collection and monitoring programs. • Working closely with geologists, hydrogeologists, and data scientists you will support construction of physics-based and data-driven models of the hydrogeology of our exploration sites and state-of-the-art water management strategies. • A key challenge will be to quantify uncertainties relevant to mining, and to identify efficient means for reducing these uncertainties as the project advances. • Conduct or support a full range of mine engineering functions, including: • Detailed design of Mingomba underground mine • Engineering trade-off studies • Cost estimation and economic analysis of alternatives • Preparation of technical documents including public disclosure documents for Mineral Resources and Reserves • Provide feedback to geological and geotechnical modeling as necessary. • Support both surface and underground facilities engineering • Apply KoBold’s Project Management standards to manage all aspects of projects • Work collaboratively across engineering disciplines and technical staff to develop the skills and procedures needed to effectively deliver mining engineering assignments • Serve as an internal technical resource and provide guidance and mentorship to junior-level staff. • Identify, develop, and follow through on value engineering opportunities • Mentor staff to support their growth and professional development. • Exercise responsible and ethical decision-making regarding company resources and conduct and adhere to KoBold’s Code of Conduct and related policies and procedures. • Perform additional responsibilities as required by business needs.

Develop and refine makeup formulas with vendors, manage multiple projects to ensure timely product launches, and collaborate with cross-functional teams to meet safety and compliance standards while driving innovation in product development.

• Support the design and delivery of foundation and structural systems across a range of infrastructure and renewable energy projects • Work closely with senior engineers and contribute to projects from concept through construction • Focus on structural design for solar tracker systems, equipment pads, and site development structures • Participate in structural engineering efforts for utility substation projects • Review project documents and develop structural Basis of Design (BOD) • Design and size shallow and deep foundations based on geotechnical recommendations and equipment loads • Perform load calculations and develop structural models using accepted FEA tools • Prepare structural drawings, elevations, details, and specifications using AutoCAD and/or Revit

• Provide strong leadership, overseeing the engineering work of the team, facilitating training, and fostering resource development to ensure the successful execution of projects. • Work closely with internal stakeholders, across multiple departments (and geographies) to ensure project execution to support company goals and business objectives. • Stay open to new ideas, technologies, and ways of working; willing to challenge the status quo, explore innovative solutions, and continuously seek improvements to drive progress and efficiency.
