Job Description
Welcome to ConocoPhillips, where innovation and excellence create a platform for opportunity and growth. Come realize your full potential here.
**Who We Are**
We are one of the world’s largest independent exploration and production companies, based on proved reserves and production of liquids and natural gas. With operations and activities in 13 countries, we explore for, develop, and produce crude oil and natural gas globally. We are challenged with an important job to safely find and deliver energy to the world. Our employees are critical to our success, and with them we power civilization.
We’re grounded by our SPIRIT Values – safety, people, integrity, responsibility, innovation, and teamwork. These values position us to deliver strong performance in a dynamic business – but not at all costs. We believe it’s not just what we do – it’s how we do it – that sets us apart.
**Fostering an Inclusive Work Environment**
To deliver superior performance, we create an environment that respects the contributions and differences of every individual. Wherever possible, we use these differences to drive competitive business advantage, personal growth and, ultimately, create business success.
**Job Summary**
Reporting to the LNG EPC Engineering Supervisor, the Senior/Staff LNG Process Engineer supports the full lifecycle of liquefied natural gas (LNG) facility design and delivery. You will shape early process concepts, guide detailed engineering with Engineering, Procurement and Construction (EPC) partners, and help bring facilities online through commissioning and start\-up (CSU). This role blends deep process design expertise with practical operability and safety focus. You will collaborate with internal teams, licensors, EPC contractors, and clients to deliver safe, reliable, and efficient facilities.
Travel averages about 25% and includes on\-site support in the U.S. Lower 48 and international locations, especially during CSU and targeted operational support windows.
**Position Overview**
**Conceptual \& Pre\-FEED Phases:**
* Define and document process design premises that align with project objectives , safety expectations, and operating strategy.
* Advise licensors, EPC contractors, and client teams on process design choices, operability, and commissioning and start\-up (CSU) considerations early, when design decisions have the most impact.
* Participate in layout, constructability, and risk\-focused reviews, including early 3D model reviews, to identify issues before they become costly changes.
* Build and maintain conceptual process simulations (for example, Aspen HYSYS or similar) to validate concepts, develop heat and material balances, and support early equipment sizing.
* Develop key early deliverables, including:
* Process Flow Diagrams (PFDs)
* Utility Flow Diagrams (UFDs)
* Preliminary Piping and Instrumentation Diagrams (P\&IDs)
* Create and update design templates and standard documentation so early engineering stays consistent and easier to execute in later phases.
**FEED, EPC \& Post Startup Phases:**
* Own the quality, accuracy, and technical integrity of process design deliverables from Front End Engineering Design (FEED) through EPC execution.
* Ensure designs meet ConocoPhillips minimum standards and agreed design bases, while supporting EPC teams with clear technical direction and timely decisions.
* Guide selection and application of critical instrumentation and control concepts to support safe, stable operations and effective start\-up.
* Lead or support rated\-case and design\-case simulations to confirm equipment and system performance across expected operating conditions.
* Support structured safety and operability reviews and close out actions, including:
* Hazard and Operability Studies (HAZOP)
* Layer of Protection Analysis (LOPA)
* P\&ID reviews
* Risk assessments and 3D model reviews
* Support LNG train walkdowns and cold box inspections to verify field readiness, completeness, and alignment with design intent.
* Work with EPC teams to confirm practical piping routing, elevations, and equipment placement in the liquefaction area, with focus on maintainability, access, and operability.
* Develop and verify process equipment specifications to ensure equipment meets performance requirements and integrates correctly with the overall process design.
* Provide technical site support during commissioning, start\-up, and post\-startup stabilization, including leadership of issue resolution where needed.
* Troubleshoot post\-startup operating issues, identify root causes, and implement solutions that improve reliability, safety, and performance.
* Develop and deliver training for engineering and operations teams supporting new facilities, tailored to the design intent and control philosophy.
* Produce operations and control deliverables such as loop descriptions, control narratives, alarm and trip summaries, and similar documentation needed for safe operation.
