The Techno-Economic Engineer is responsible for developing and maintaining dynamic operating and capital cost models. These models will drive decision‑making by providing transparent, auditable, and flexible cost outputs for multiple mining and processing projects. The role ensures that sensitivities, value drivers, and cost breakdowns are clearly identified, enabling robust financial and operational planning. The engineer will be responsible to identify, model, and integrate all technical elements impacting the economics of our projects across the full value chain from inputs, processing, to outputs, and finally integrating the financial models with our financial modelling experts' support. In addition, the engineer may also be required to develop or update the financial model itself, ensuring seamless integration between technical cost outputs and corporate finance requirements.

Position: Techno Economic Engineer
Location: Centurian, Southdowns Office Park
Employment Type: Full time

• Education: Degree in Mining Engineering, Industrial Engineering, Economics, or related technical discipline.
• Experience: 4+ years in mining cost engineering, techno economic modelling, or project controls.
• Technical Expertise: Strong understanding of mining schedules, operational drivers, and cost structures.
• Advanced Excel modelling (Power Query, Power Pivot, VBA desirable).
• Power BI dashboard development and data modelling.
• Familiarity with scheduling tools (e.g., Deswik, MineSched, Vulcan) and integration with cost models.
• Knowledge of procurement, vendor pricing, and cost escalation logic.
• Financial modelling skills: cashflow generation, discounting, tax treatment, and scenario analysis.
• Analytical Skills: Ability to run scenario analysis, sensitivities, and identify key value drivers.
• Communication: Skilled at translating technical outputs into clear insights for executives and stakeholders.
• Good leadership and communication skills, with proven ability to work in a team and engage with key stakeholders.
• Proficient in Microsoft Office (Word, PowerPoint, Excel, Outlook).

• Dynamic Cost Model Development: Build and maintain a cost model driven by the LoM schedule and operational drivers. Ensure the model adapts to different mining options, sequencing, and processing variants. Incorporate sensitivity analysis and value‑driver identification into the model framework.
• Cost Structuring and Classification: Split costs by Work Breakdown Structure (WBS), procurement package, discipline, commodity, and client‑specific attributes. Classify costs into Capex, Sustaining Capital (SIB), and Opex categories. Incorporate full labour detail down to individual job profiles and Trackless Mobile Machines (TMMs).
• Financial Model Development: Provide inputs into the corporate financial model (cashflows, cost breakdowns, sensitivities). Where required, build or maintain the financial model itself, ensuring alignment with accounting, tax, and financing assumptions. Validate integration between cost model outputs and financial model results.
• Governance and Documentation: Maintain auditability and traceability of all assumptions, inputs, and calculations. Document model logic, data lineage, and user guidelines. Support peer reviews, version control, and model governance processes.

• Dynamic LoM-driven cost model with scenario and variant capability.
• Control Budget Estimate (CBE) with full cost breakdowns.
• Cashflow projections aligned with financial reporting.
• Financial model (where required) and/or validated financial model inputs.
• Power BI dashboards for project and executive reporting.
• Sensitivity and value-driver analysis reports.
• Labour and TMM registers with cost roll-ups.
• Model documentation and governance records.
