Gas Business Modeler (Relocation to Saudi Arabia is required)

Key Responsibilities

• Maintain and apply mathematical, computational, or simulation models to support engineering design, operational analysis, project planning, and performance optimization in gas sector in order to simulate real-world conditions, test scenarios, and predict outcomes to guide engineering and business decisions.
• Develop and maintain steady-state or dynamic simulation models using industry-standard software (e.g., HYSYS, PROSPER, GAP, PipePhase, etc.).
• Create simulation models for process units, pipeline networks, production systems, or processing facilities.
• Apply thermodynamic, hydraulic, or economic principles to ensure model accuracy.
• Collect and validate data from field measurements, historical performance, or engineering studies.
• Ensure data consistency and reliability for accurate modeling and forecasting.
• Run simulations under various operating conditions or scenarios (e.g., equipment failure, capacity changes, production decline, new well connections).
• Analyze results to identify performance bottlenecks, capacity limits, or optimization opportunities.
• Recommend design or operational changes based on model findings.
• Provide modeling support for FEED (front-end engineering Design ) studies, project design, and operational troubleshooting.
• Support capital project evaluations and feasibility studies with technical insights from models.
• Test and validate models against real-time or historical data to ensure accuracy.
• Calibrate models to match field behavior and improve predictive capability.

Minimum requirements

• Hold a Bachelor degree in Engineering (preferably Chemical, or Mechanical Engineering)
• Minimum of 10 years of experience in gas process modeling and simulation, preferably in gas sector.
• Professional certifications (e.g., in simulation software or project economics) are preferred.
• Experience in model-based decision support or digital transformation initiatives (e.g., digital twins, predictive analytics) is a plus.
• Proficiency in Process simulation such as: HYSYS, PRO/II, Aspen Plus.
• Skills in production systems modeling such as: PROSPER, GAP, PIPESIM, Preferably with Pipeline network modeling such as: PLEXSYS, OLGA (for dynamic models).
• A strong understanding of Thermodynamics, fluid mechanics, mass and energy balances.
• Experience in Data analysis and visualization tools (e.g., Excel, Python, MATLAB, Power BI).
• Experience in Economic modeling (e.g., NPV, IRR, cash flow projections), Preferably familiarity with Saudi Aramco standards and procedures.
• Analytical thinking and problem-solving skills as well as attention to details and accuracy in modeling.
