Process Modeling Engineer you'll be at the forefront of our innovation, driving specialty chemical solutions forward. You'll collaborate with a diverse group of passionate individuals to deliver sustainable solutions to advance mobility, improve wellbeing, and enhance modern life.

The Process Modeling Engineer plays a critical role in optimizing and transforming manufacturing performance through advanced process modeling, simulation, and data-driven analysis. This role develops and deploys both physics-based and data-based models to support process design, scale-up, troubleshooting, optimization, and long-term strategic planning. The engineer also leads the creation of modeling standards, training programs, and strategic frameworks that elevate modeling capabilities across the organization.

• Develop, validate, and maintain physics-based process models (e.g., heat/mass transfer, reaction kinetics, fluid dynamics, unit operations).
• Build and apply data-driven models using statistical, machine learning, or hybrid modeling approaches to identify trends, correlations, and optimization opportunities.
• Conduct steady-state and dynamic simulations for process design, capacity analysis, debottlenecking, and energy efficiency assessments.
• Support troubleshooting and root cause analysis by using modeling to reproduce plant behavior and test hypotheses.
• Collaborate with R&D, operations, and process engineering to translate lab/pilot data into full-scale manufacturing models.

• Develop and maintain modeling standards, documentation practices, and validation protocols to ensure consistency, quality, and sustainability of modeling assets.
• Establish templates, guidelines, and workflows for physics-based and data-driven modeling across the engineering organization.
• Lead governance activities to ensure models are used responsibly, accurately, and with defined lifecycle management.

• Design and deliver training programs, workshops, and hands‑on sessions for engineers, operators, and technical staff on modeling tools, methodologies, and best practices.
• Mentor engineering teams on model interpretation, limitations, and appropriate use in decision‑making.
• Help cultivate a culture of data literacy, model‑informed design, and digital fluency across the organization.

• Develop and communicate a strategic roadmap for modeling capabilities, including tool selection, digital technologies, and long-term capability growth.
• Evaluate and integrate emerging modeling technologies—such as AI/ML, advanced simulation platforms, and digital twin solutions.
• Collaborate with global engineering and operations leaders to align modeling strategy with broader engineering, manufacturing, and corporate objectives.
• Provide thought leadership in the areas of advanced analytics, digital process design, and predictive manufacturing.

• Work closely with manufacturing, quality, R&D, EHS, and supply chain teams to ensure models support operational excellence, process safety, and product quality.
• Support capital project teams with modeling contributions for feasibility studies, conceptual design, and detailed engineering.
• Present model results and recommendations to technical and non‑technical audiences, including senior leadership.

• Master’s or PhD in Chemical Engineering, Process Modeling, Computational Methods, or related fields.
• 3+ years of experience in process engineering, process modeling, or advanced analytics within chemical, materials, or related manufacturing industries.
• Strong experience with process simulation tools (e.g., Aspen Plus,…
