About the Role

We are seeking an experienced engineer to lead the development and operationalization of an integrated LNG feedgas forecasting, flow assurance, and optimization capability supporting Louisiana LNG.

This role sits at the intersection of natural gas transportation, LNG operations, hydraulic modeling, gas quality management, commercial optimization, and operational decision support. The successful candidate will be responsible for understanding how upstream pipeline, storage, gas quality, and commercial activities influence LNG terminal operations and developing predictive tools, models, and workflows that improve operational reliability and commercial decision making.

This position will serve as the primary technical lead supporting the evolution from reactive feedgas monitoring to predictive feedgas intelligence, enabling earlier visibility of changes in gas quality, pressure, flow, and supply reliability across the upstream transportation network. The capability is intended to support nominations, contingency planning, LNG operating decisions, and feedgas optimization.

Duties and Responsibilities

Feedgas Flow Assurance & System Optimization

• Develop and maintain hydraulic and flow assurance models for interstate and intrastate natural gas transportation systems.
• Perform steady-state and transient hydraulic simulations to evaluate system performance under normal and abnormal operating conditions.
• Analyze the impacts of compressor outages, pipeline maintenance, storage withdrawals, receipt point disruptions, and market changes.
• Support short-term and long-term gas supply planning activities through system modeling and scenario analysis.
• Identify capacity constraints and develop mitigation strategies.

LNG Feedgas & Process Optimization

• Analyze the impact of feedgas composition, pressure, and flow variability on LNG facility performance.
• Evaluate feedgas quality trends, including nitrogen, BTU, Wobbe, CO, C6+, and other critical parameters.
• Support LNG operating decisions through forecasting and scenario analysis.
• Collaborate with LNG Operations to optimize facility performance, operating envelopes, and feedgas management strategies.
• Support development of predictive capabilities for gas quality and facility performance forecasting.

Commercial & Gas Supply Planning Support

• Support nomination, scheduling, and gas supply optimization activities.
• Evaluate transportation, storage, and supply alternatives.
• Analyze impacts of market conditions, transportation constraints, and supply interruptions.
• Work closely with commercial teams, schedulers, gas controllers, and supply planners.
• Support month-ahead, week-ahead, day-ahead, and intraday gas supply planning activities.

Operational Intelligence & Data Analytics

• Integrate operational, commercial, SCADA, gas quality, and market data into decision-support workflows.
• Analyze forecast versus actual performance to improve predictive accuracy.
• Develop automated reports, dashboards, and operational intelligence tools.
• Identify upstream drivers impacting LNG feedgas reliability and quality.
• Communicate findings to Operations, Gas Supply, Commercial, and leadership teams.

Skills and Experience

Required Qualifications

• Bachelor's degree in Engineering is required, preferably in Mechanical, Chemical, Petroleum, or Civil Engineering. Candidates with other engineering disciplines will also be considered where they can demonstrate relevant industry experience.
• 8-15+ years of experience in natural gas transmission, LNG operations, gas supply, flow assurance, or system planning.
• Direct experience with interstate or intrastate natural gas transportation systems.
• Experience performing hydraulic modeling and system optimization.
• Experience supporting operational decision making during outages, constraints, and abnormal operating events.
• Experience in natural gas transmission systems, compressor stations, gas storage facilities, gas quality analysis, flow assurance, hydraulic simulation, pressure and capacity analysis, and pipeline operations.
• Experience with one or more pipeline modeling and simulation tools, such as Gregg Engineering, Synergi Gas, Pipeline Studio, SPS, Atmos SIM, BRE ProMax, or comparable hydraulic modeling platforms.

Preferred Qualifications

• Experience supporting LNG export facilities through operations, optimization, gas supply planning, or feedgas delivery activities.
• Understanding of LNG feedgas specifications, nitrogen management, gas quality impacts, LNG process fundamentals, and facility operating constraints.
• Experience in gas scheduling, nominations, or commercial operations.
• Knowledge of FERC-regulated pipeline operations.
• Experience with SCADA, operational data systems, and data analytics platforms.
• Experience supporting transportation agreements, storage optimization, and supply portfolio management.
• Exposure to machine learning, forecasting, or operational decision-support systems.
