• Regularly interact with internal and external stakeholders to manage the project charter for the simulation tools development at Graymont. In collaboration with Plant O&M, EHS, process engineering, decarbonization engineering, and OT/Controls teams, leads in-depth analysis and conceptual thinking on how to provide simulation tools that meet stakeholders' requirements. Can handle vague and complex simulation requirements and break them down into manageable, value-added modeling tools
• Secures the confidentiality and consistent utilization of the tools developed, in collaboration with Engineering Support and documentation teams
• Facilitate cultural and technical change aligned with the simulation tools deployment initiatives.

Safety, Environmental & Regulatory Compliance

• Champion safety as a core value across all functions.
• Work with plant and HSE teams to ensure compliance with internal standards and external regulations.
• Understand combustion practices and emissions limits and other regulatory requirements.

Qualifications

• Education: Master's or Ph.D. degree in Chemical, Mechanical, or Controls Engineering, or a related field.
• Professional Experience: 5 to 10 years of experience is preferred. Backgrounds in the lime, cement, chemical, mining, oil and gas, or other heavy industrial sectors will be advantageous. Experience in decarbonization technologies or engineering is also considered an asset.

Technical Requirements:

• Advanced knowledge Process Modeling & Simulation (Static/Dynamic), programming languages, data analysis, Visualization & Reporting.
• Strong understanding of chemical and separation processes, process control systems, and instrumentation.
• Strong knowledge of combustion/calcination processes beneficial.
• Proficient in heat and mass balance calculations.
• Relevant Experience: Project management and plant commissioning experience preferred.
• Travel Requirements: Willingness to travel regularly throughout the U.S. and Canada (up to 50%).
• Language Skills: English fluency required; proficiency in French or Spanish considered an asset.
