With our significant investment in technology and infrastructure, we strive to maximize the value of the energy we produce for the world along with a commitment to enhance Aramco’s value to society. Headquartered in the Kingdom of Saudi Arabia, and with offices around the world, we combine market discipline with a generations’ spanning view of the future, born of our nine decades experience as responsible stewards of the Kingdom’s vast hydrocarbon resources. This responsibility has driven us to deliver significant societal and economic benefits to not just the Kingdom, but also to a vast number of communities, economies, and countries that rely on the vital and reliable energy that we supply. We are one of the most profitable companies in the world, as well as amongst the top five global companies by market capitalization. Overview Engineering Services are seeking a highly qualified and experienced process modeling specialist with expertise in process simulation, digital twin development, and advanced modeling techniques. The ideal candidate will have a strong background in building and validating simulation models for gas, refinery and other oil and gas units, including kinetic reactor models, using tools such as Aspen HYSYS, AVEVA ROMeo, APS, and Honeywell UniSim. A preference will be given to candidates with experience in both Sequential Modular and Equation Oriented model development. They will provide technical leadership in process modeling and simulation, drive the development of digital solutions such as process simulation twins. The candidate will also mentor junior engineers, deliver company-led training courses, and contribute to troubleshooting operational issues while developing innovative technologies to further enhance operation. Experience with hybrid modeling techniques and the integration of AI/ML with simulation tools is desirable. Key Responsibilities Develop and validate detailed process simulation models for refinery units and other hydrocarbon processing facilities using tools such as Aspen HYSYS, AVEVA ROMeo, APS, and Honeywell UniSim. Build and optimize kinetic reactor models to accurately represent complex chemical reactions and process conditions. Provide technical leadership in process modeling and simulation, guiding cross-functional teams to implement modeling solutions for operational and strategic decision-making. Lead the development of digital twin solutions, integrating process simulation models with other software components such as data analytics, machine learning, and optimization systems. Troubleshoot operational issues in hydrocarbon processing units by analyzing simulation results and providing actionable recommendations. Collaborate with internal stakeholders to identify modeling requirements, translate them into functional specifications, and deliver tailored solutions. Mentor junior engineers and deliver company-led training courses on process modeling. Stay updated on emerging technologies and methodologies, such as hybrid modeling techniques and the application of AI/ML in process simulation, and apply this knowledge to improve modeling accuracy and efficiency. Develop and implement best practices, standards, and procedures for process modeling and simulation within Saudi Aramco. Prepare technical reports, presentations, and documentation to communicate findings and recommendations to stakeholders. Minimum Requirements A minimum of a bachelor degree in Chemical Engineering. A MSc/PhD are preferred. A minimum of 15+ years of experience in process modeling and simulation in the oil and gas industry. Strong expertise in process simulation tools such as Aspen HYSYS, AVEVA ROMeo, APS, and Honeywell UniSim. Proficiency in one or more of these tools is expected. Proven experience in building and validating kinetic reactor models and simulating complex refinery processes. Demonstrated ability to provide technical leadership and guide cross-functional teams in process modeling and simulation projects. Strong understanding of gas and refinery operations, process modelling, and troubleshooting. Excellent problem-solving skills, with the ability to translate operational challenges into modeling opportunities. Strong communication and interpersonal skills, with the ability to mentor junior engineers and deliver training programs. Proficiency in English, both written and verbal, with the ability to write technical reports and present findings to stakeholders.
