While Process Simulate focuses on modeling and testing manufacturing processes virtually, Process Engineers are responsible for designing and implementing these processes in real-world settings. Both roles require technical expertise, but Process Simulate emphasizes simulation skills, whereas Process Engineers focus on practical process development and optimization.

How does a Process Simulate specialist typically collaborate with engineering and production teams during a project?

A Process Simulate specialist works closely with both engineering and production teams to develop, test, and optimize manufacturing processes in a virtual environment before implementation on the shop floor. This collaboration involves regular meetings to review simulation results, gather feedback on proposed process changes, and ensure alignment with production goals and constraints. Effective communication is key, as the specialist must translate technical simulation data into actionable insights for engineers and operators. Such teamwork helps identify potential bottlenecks, improve efficiency, and reduce costly errors during actual production ramp-up.

What is a Process Simulate?

A Process Simulate engineer specializes in using simulation software—such as Siemens Process Simulate—to design, validate, and optimize manufacturing processes in a virtual environment. Their main tasks include creating digital models of production lines, testing various process scenarios, and identifying improvements before physical implementation. This helps manufacturers save time, reduce costs, and minimize errors by addressing issues early in the design phase. Process Simulate engineers often collaborate closely with production, quality, and design teams to ensure efficient and error-free manufacturing workflows.

Job description

We're looking for an experienced process scientist or engineer with a strong foundation in first-principles modeling and chemical engineering to accelerate how we scale products and evaluate process changes across R&D and manufacturing. You will build and validate mechanistic and hybrid models that capture the physics of our materials and processes enabling faster, smarter decisions from pilot through full-scale production. This role sits at the intersection of engineering fundamentals, computational modeling, and real-world manufacturing impact.
As a senior individual contributor, you'll lead the development of process models that simulate, predict, and de-risk scale-up, reducing our reliance on trial-and-error and compressing the time from formulation to production. You'll work closely with process engineers, R&D scientists, and our data science team to connect physics-based understanding with data-driven approaches, building toward hybrid models and digital twins that can be deployed across our manufacturing network.
We're building new capabilities and we want people who are energized by that. Beyond building models, you'll help define how process modeling is practiced across the organization by establishing scalable methodologies, reusable simulation frameworks, and best practices that raise the bar for how we design, optimize, and transfer processes. This is an opportunity to do technically deep, high-impact work while shaping how modeling and simulation are applied in a materials and manufacturing environment.
Key Responsibilities
Process Modeling & Simulation
  • Develop and validate first-principles and mechanistic models for key unit operations and process systems, capturing the physics of heat transfer, mass transfer, fluid dynamics, and reaction/dissolution kinetics relevant to our materials and processes.

  • Build process flowsheet models using tools like Aspen Plus to simulate end-to-end process behavior and evaluate the impact of process changes, new formulations, and equipment configurations.

Scale-Up & Process Transfer
  • Lead modeling efforts that bridge pilot-scale experiments to manufacturing-scale operations by identifying scale-dependent risks, informing equipment selection, and defining operating windows.

  • Develop scale-up and scale-down frameworks that reduce experimental cycles and accelerate the path from product development to production readiness.

  • Work with the Engineering Technology Center to test and adopt your models into process R&D.

Hybrid Modeling & Digital Twin Development
  • Partner with the data science team to integrate first-principles models with data-driven approaches, building hybrid models that combine physical understanding with empirical learning.

  • Contribute to the development and evolution of digital twins for critical process systems, supporting prediction, optimization, and what-if scenario analysis across the manufacturing network.

Analysis, Visualization & Decision Support
  • Translate complex simulation outputs into clear, actionable engineering recommendations that inform R&D direction, process design, and manufacturing decisions.

  • Develop compelling visualizations and technical narratives that enable cross-functional teams, from scientists to plant leadership, to quickly understand and act on modeling insights.

Methodology, Standards & Capability Building
  • Establish scalable modeling methodologies and reusable simulation workflows that can be applied across products, processes, and manufacturing lines.

  • Act as a technical resource on process modeling best practices by mentoring team members, guiding analytical approaches, and elevating how modeling is used to support decision-making across the organization.

  • Stay current with emerging tools, methods, and computational approaches in process simulation, multiscale modeling, and hybrid/digital twin frameworks.

Qualifications
Education
  • Bachelor's degree in Chemical Engineering, Mechanical Engineering, Materials Science, Polymer Science, Physics, or a related technical field; Master's or PhD strongly preferred

Experience
  • 5+ years applying process modeling, simulation, or computational engineering to real-world problems in materials, chemicals, polymers, or related manufacturing environments

  • Track record of building mechanistic or first-principles models that informed scale-up decisions, process design, or operational improvements - from model development through validation and deployment

  • Experience bridging pilot-scale and manufacturing-scale operations, with a practical understanding of how process physics changes across scales

Technical Skills
  • Strong proficiency in process simulation tools such as Aspen Plus, Aspen HYSYS, gPROMS, or equivalent flowsheet modeling platforms

  • Solid foundation in transport phenomena, thermodynamics, reaction/dissolution kinetics, and fluid dynamics as applied to process modeling

  • Experience with CFD or finite element analysis tools (e.g., ANSYS Fluent, COMSOL Multiphysics, Star-CCM+) for unit operation or equipment-level modeling

  • Proficiency in Python for custom model development, data analysis, and automation of simulation workflows

  • Experience developing or contributing to hybrid models that integrate physics-based and data-driven approaches (preferred)

  • Familiarity with digital twin concepts, reduced-order modeling, or model deployment in operational environments (preferred)

  • Familiarity with statistical methods, design of experiments (DOE), and uncertainty quantification as applied to model validation and process characterization (preferred)

  • Experience with version control (Git) and reproducible computational workflows

Who you are
  • Strong communicator who can translate complex simulation results into clear engineering recommendations for scientists, process engineers, manufacturing teams, and leadership

  • Comfortable operating in ambiguous, cross-functional environments and taking ownership of high-impact problems without waiting for direction

  • Self-directed senior IC who leads through technical credibility by shaping modeling approaches, driving alignment across teams, and raising the bar for how process knowledge is captured and reused

  • Energized by continuous learning and staying at the forefront of process modeling, simulation, and computational engineering
