A major component of this role will be using dynamic simulation for developing and deploying high-fidelity dynamic simulation models to support advanced control strategies, operator training systems, and digital twin initiatives for LNG facilities. This role bridges process engineering and automation, enabling safer, more efficient LNG plant operations through simulation-driven insights.

KEY RESPONSIBILITIES

• Apply engineering expertise to design and implement world-class natural gas liquefaction processes and equipment.
• Perform advanced process cycle simulations for natural gas liquefaction and related systems.
• Complete detailed thermal design of proprietary heat transfer equipment (coil wound heat exchanger) manufactured by Honeywell LNG.
• Conduct relief and depressuring scenario analyses for proprietary equipment using established tools and methodologies.
• Support plant operations through startup, performance testing, troubleshooting, control scheme implementation, and continuous improvement initiatives.
• Collaborate closely with cross-functional teams—including commercial, project management, mechanical design, manufacturing, machinery, R&D, and start-up—to ensure seamless project execution, and drive product development and improvement.
• Participate in P&ID reviews and HAZOPs at contractor offices to ensure safety, operability and design integrity.
• Develop, configure, and validate dynamic simulation models using UniSim Design (steady-state and dynamics).
• Perform dynamic studies including startup, shutdown, and cooldown sequences, compressor trip scenarios, 
• Emergency shutdown (ESD) and blowdown analysis
• Develop and validate control narratives, cause & effect matrices, and alarm management strategies
• Troubleshoot plant operational issues using simulation and digital twin environments
• Domestic and international travel to clients’ offices, contractors, and plant sites expected about 10-15 percent of the time.
