Job Description
Mariana Minerals is looking for a Pyrometallurgical Process Engineer to lead the development and deployment of high-temperature refining and thermal processing systems. The role involves designing, modeling, and scaling pyrometallurgical unit operations, as well as supporting software tools for capital project execution and automated plant optimization.

Requirements

  • Lead pyrometallurgical process scopes from concept and modeling validation through detailed engineering, installation, commissioning, and ramp-up
  • Develop detailed heat and material balances for high-temperature process trains
  • Design and validate thermal process flowsheets and PFDs/P&IDs for pyrometallurgical circuits
  • Build first-principles thermodynamic and kinetic models for high-temperature reactors and furnaces
  • Model and optimize phase equilibria, slag chemistry, metal recovery, refractory performance, and energy efficiency
  • Define specifications and operating envelopes for high-temperature process equipment
  • Identify, evaluate, and implement process improvements to maximize metal recovery and minimize energy consumption
  • Collaborate closely with R&D, lab teams, and pilot-plant engineers
  • Work with environmental and controls teams to design and optimize off-gas handling systems
  • Partner with software and machine-learning teams to automate process-engineering workflows and develop advanced control, optimization, and digital-twin models
