• Bachelor’s degree or higher in Science or Engineering, other related technical field, or foreign equivalent.
• 7 or more years of experience in process controls engineering within LNG or a related process industry.
• Experience developing, updating, and finalizing PFDs, UFDs, heat and material balances, and P&IDs.
• Hands-on experience with process control development, implementation, and operational support.
• Willing and able (with or without reasonable accommodation) to travel domestically and internationally 25% of the time on a yearly basis.

Nice To Haves

• Experience supporting commissioning, start-up, and live operations on major capital projects.
• Strong working knowledge of process controls, dynamic behavior of facilities, and interaction between process design and operations.
• Ability to clearly communicate technical information through written reports and verbal presentations.
• Demonstrated ability to work effectively with operations, project teams, and external partners.

Responsibilities

• Contribute to development and refinement of the project and process design basis, with a strong focus on operability, controllability, and production performance.
• Advise licensors, EPC contractors, and client teams on process technology operations, control philosophy, and start-up considerations.
• Review and develop Process Flow Diagrams (PFDs), Utility Flow Diagrams (UFDs), and Material Selection Diagrams (MSDs) in close coordination with the Process Design team to ensure designs support stable operation.
• Actively participate in Piping and Instrumentation Diagram (P&ID) development and reviews, ensuring alignment with control strategies and operational needs.
• Participate in process safety and risk reviews, including: Hazard Identification Studies (HAZIDs) Process Hazard Analyses and Hazard and Operability Studies (PHA/HAZOP) Layer of Protection Analyses (LOPA) Safety Integrity Level (SIL) reviews Quantitative Risk Assessments (QRA)
• Review process equipment design with an operations and controls lens, including sizing, internals selection, residence time, nozzle sizing, pressure drop allowances, and configuration.
• Review piping hydraulics and layouts to prevent unstable operation, slugging, and transient conditions, and to ensure acceptable straight-run lengths, mixing distances, and nozzle configurations.
• Participate in 3D model development and review cycles to confirm accessibility, operability, and maintainability of equipment, valves, and instrumentation.
• Perform process controls analyses, including control valve sizing, trim selection, and evaluation of control strategies.
• Support project economic evaluations by identifying operability risks, production impacts, and optimization opportunities.
• Review equipment specifications, datasheets, and vendor bid packages to confirm alignment with operating and control requirements.
• Maintain the quality, accuracy, and technical integrity of process deliverables throughout all project phases.
• Ensure ConocoPhillips minimum standards are applied consistently across process and control design.
• Update and finalize key engineering deliverables, including PFDs, UFDs, heat and material balances (H&MBs), and P&IDs.
• Participate in manufactured equipment reviews, module checkouts, and P&ID walkdowns to verify readiness for commissioning.
• Provide on-site support during commissioning, start-up, and post-startup stabilization.
• Troubleshoot post-startup operating issues, identify root causes, and support implementation of sustainable solutions.
• Lead or support revamp and debottlenecking studies aimed at improving capacity, availability, reliability, or resolving recurring operational issues.

Benefits
