Senior Simulation Engineer

About the Role :

We are seeking an experienced Simulation Engineer with expertise in Aviva DynSim and hands-on experience modeling rotating equipment (blowers, compressors), heat exchangers, combustors, and Gibbs reactors . The ideal candidate will develop high-fidelity dynamic simulations to optimize process performance, troubleshoot operational challenges, and support engineering design in industries such as Oil & Gas, Petrochemicals, Power Generation, or Hydrogen / Carbon Capture .

Key Responsibilities :

• Develop, validate, and maintain dynamic simulation models in Aviva DynSim for systems involving :
• Rotating equipment : Blowers, compressors (centrifugal / reciprocating), turbines.
• Thermal systems : Heat exchangers (shell & tube, plate), combustors, fired heaters.
• Reactors : Gibbs reactors (equilibrium-based), catalytic reactors, reformers.
• Perform transient analysis to study startup / shutdown scenarios, trip events, and control system response.
• Integrate simulations with real plant data for model tuning and predictive maintenance.
• Support operator training simulators (OTS) by creating realistic equipment behavior models.
• Collaborate with process engineers to optimize compressor surge control , heat exchanger fouling, and combustion efficiency.
• Conduct sensitivity studies to evaluate process modifications (e.g., feedstock changes, capacity expansions).
• Troubleshoot operational issues (e.g., vibration in blowers, combustion instability, reactor maldistribution).
• Document assumptions, validation results, and best practices for simulation workflows.
