Staff Process Modeling Engineer: Mineral Refining & Automation

Warmada; Houston (TX); Sur place; USD 160 000 - 210 000; Plein temps

Résumé du poste

Mariana Minerals is seeking a Staff Process Modeling Engineer to drive the development and optimization of heat and material balance models for state‑of‑the‑art mineral refining facilities. You will translate lab and pilot data into robust process models that inform design decisions from concept through commercial deployment.

You will lead modeling standards, mentor junior engineers, and collaborate with R&D, pilot ops, and project teams to ensure model fidelity and integration with data sheets,

Qualifications

• Bachelor’s degree or higher in Chemical Engineering, Mechanical Engineering, Process Engineering, Metallurgical Engineering, or related field.

Responsabilités

• Develop steady-state and dynamic process models to establish heat and material balances for integrated mineral refinery systems using ASPEN, SysCAD, OLI, or METSIM.
• Automate equipment sizing (reactors, heat exchangers, filters, crystallizers, evaporators, and separators) based on model outputs and link to datasheets.
• Develop and maintain process simulation databases with traceability between modeling assumptions, test data, and engineering deliverables.
• Calibrate and reconcile models using pilot or plant data to ensure fidelity and predictive accuracy.
• Conduct process optimization studies evaluating energy recovery, recycle strategies, and material efficiency improvements.
• Develop dynamic process models to validate PLC/DCS programming and evaluate buffer sizing.
• Link process models to CAPEX and OPEX estimation tools, automating technoeconomic model development.
• Document modeling methodologies and results for design reviews, techno-economic assessments, and regulatory submissions.
