Experienced Reservoir Simulation Engineer

EPAM is a global technology services and engineering company operating in 50+ countries, with recognized capabilities across cloud, AI, data, and core systems engineering. In the Energy sector, EPAM partners with leading Utilities, Oil & Gas majors, Renewable Energy developers, and emerging LNG operators to modernize infrastructure, accelerate digital transformation, and build the data and AI platforms defining next-generation energy operations. Our engineering-first approach and sector depth have established EPAM as a trusted strategic partner to some of the largest energy enterprises in North America.

EPAM is looking for an Experienced Reservoir Simulation Engineer to join our Energy practice (Energy Competency, Subsurface & Wells) in Houston, Texas. You will work hands-on with complex reservoir simulation models, focusing on building, refactoring, converting, and quality-assuring dynamic models. The role requires strong practical simulation expertise and the ability to work directly with asset and subsurface teams to ensure models are technically robust and fit for use.

Hands-on experience with CMG, Eclipse, or Intersect is required. Experience with Intersect and with model migration between simulators is particularly valuable. These platforms are also represented in EPAM's existing reservoir simulation capability.

We are looking for someone who is first and foremost a reservoir simulation specialist: comfortable taking an existing complex model apart, understanding how it works, rebuilding or refactoring it where necessary, migrating it between simulation platforms, and demonstrating that the resulting model behaves correctly.

Req# 1060246539

Responsibilities

• Build and refactor reservoir simulation models, including model setup, initialization, and configuration
• Review existing simulation models and improve their structure, quality, robustness, and performance
• Model conversion and migration
• Convert and migrate models between CMG, Eclipse, and/or Intersect, validating results following conversion
• Troubleshooting, QA/QC, and history matching
• Troubleshoot model issues including initialization, convergence, numerical stability, and simulation performance
• Perform model QA/QC and identify inconsistencies in model configuration, data, and results
• Support history matching and run simulation cases to confirm model behavior
• Collaboration and documentation
• Work closely with subsurface and asset teams to understand existing models, assumptions, and requirements
• Clearly document model changes, assumptions, validation results, and technical issues

Requirements

• Education: Bachelor's or Master's degree in Petroleum Engineering, Reservoir Engineering, or a related discipline
• Simulation experience: Significant professional experience in reservoir simulation and dynamic reservoir modeling
• Platform expertise: Strong hands-on experience with at least one of CMG, Eclipse, or Intersect
