**About us**
At ExxonMobil, our vision is to lead in energy innovations that advance modern living and a net\-zero future. As one of the world’s largest publicly traded energy and chemical companies, we are powered by a unique and diverse workforce fueled by the pride in what we do and what we stand for.
The success of our Upstream, Product Solutions and Low Carbon Solutions businesses is the result of the talent, curiosity and drive of our people. They bring solutions every day to optimize our strategy in energy, chemicals, lubricants and lower\-emissions technologies.
We invite you to bring your ideas to ExxonMobil to help create sustainable solutions that improve quality of life and meet society’s evolving needs. Learn more about our **What** and our **Why** and how we can work **together**.
**About Houston**
-----------------
ExxonMobil's state\-of\-the\-art campus north of Houston serves as home to its Upstream, Product Solutions and Low Carbon Solutions businesses and their associated service groups. The facility opened in 2014 and accommodates more than 10,000 employees and visitors.
By bringing many global functional groups together, the campus provides employees with the tools and capabilities needed today, and in the future, to achieve business objectives and accelerate the discovery of new resources, technologies and products. It was designed to foster improved collaboration, creativity and innovation and enhance the company’s ability to attract, develop and retain the top talent in the industry.
The campus is located in Spring, Texas, on 385 wooded acres immediately to the west of Interstate Highway 45 (I\-45\), at the intersection of I\-45 and the Hardy Toll Road, approximately 25 miles from the cultural vibrancy of downtown Houston.
The campus was constructed to the highest standards of energy efficiency and environmental stewardship. Its design incorporates extensive research into best practices in building and workplace design through extensive benchmarking of the world’s top academic, research, and corporate facilities.

**What role you will play in our team**
---------------------------------------
ExxonMobil is seeking a qualified and experienced flow assurance engineer to provide technical support and expertise to its development projects and production operations. The candidate would be part of ExxonMobil’s Flow Assurance Engineering team in ExxonMobil Technology and Engineering Company, which provides corporate\-wide technical and advisory support for both design and operation of ExxonMobil’s diverse global portfolio of assets, new developments, and low\-carbon solutions initiatives.
The Flow Assurance Lead Engineer is responsible for the design of oil and gas production systems and assessment of their operability, including wells, flowlines and risers, production and injection facilities, and pipelines. The Lead Flow Assurance Engineer uses analytical and computational tools to predict the transient multiphase flow and thermal behavior of the production system and develops and documents functional requirements and operational strategies to prevent, mitigate, and remediate vulnerabilities associated with gas hydrate formation, wax deposition, and other solids.
**What you will do**
--------------------
* Develop and apply Flow Assurance design and operating strategies across deepwater projects, unconventional developments, midstream/downstream pipelines, R\&D initiatives, and low‑carbon solutions.
* Provide full life‑cycle Flow Assurance support from concept evaluation through detailed engineering, commissioning/startup, and steady\-state operations.
* Assess and recommend design and operating philosophies, clearly articulating strengths, limitations, and strategic implications for management decision\-making.
* Collaborate across disciplines (Marine, Risers, Pipelines, Subsea, Facilities, Reservoir) and interface with suppliers and contractors to align scopes, deliverables, and technical expectations.
* Perform fluid characterization using thermodynamic simulation to model PVT behavior of produced fluids.
* Conduct steady‑state flow modeling for sizing gas/water injection systems and pipelines.
* Execute multiphase flow modeling (steady\-state and transient) to design production systems, artificial lift requirements, insulation needs, and to evaluate operational transients such as slugging, cool‑down/warm‑up, startup, shutdown, and blowdown.
* Analyze and predict solids formation and deposition behaviors (hydrates, sand, wax, scale, asphaltenes, etc.) using modeling and laboratory methods.
* Evaluate erosion and corrosion risks and collaborate with Materials Engineers to guide material selection.
* Mentor and guide less experienced engineers in the Flow Assurance discipline.
* Steward and revise Flow Assurance design/selection guides, software, and tools.
* Sustain and promote
