CFD Engineer — Multiphase & Transport Phenomena

About Us

At Exxon Mobil, 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.

Exxon Mobil'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.

At Exxon Mobil, one of the world’s largest publicly traded energy providers and chemical manufacturers, we develop and apply next‑generation technologies to help safely and responsibly meet the world’s growing needs for energy and high‑quality chemical products. Affordable and sustainable energy solutions are required to advance global prosperity. We invest in technology and communities to bring the world better energy. Within Exxon Mobil Technology and Engineering Company, our teams leverage our world‑class facilities to research and develop the energy solutions of tomorrow.

• Develop and apply fluid dynamics and transport phenomena models to guide the development and design of new process technologies with applications across all Exxon Mobil companies: upstream, product solutions, and low‑carbon solutions.
• Work collaboratively as part of a cross‑discipline team complementing expertise in fundamental and pilot plant experimentation, process engineering, and equipment design with your expertise in applied and computational fluid dynamics and transport phenomena. Though this role will be modeling focused, you will contribute to experimental design and execution.
• Serve as a subject matter expert in topics related to fluid dynamics, transport phenomena, and CFD to the global research and process engineering communities.
• Develop and maintain advanced computational fluid dynamics and transport phenomena modeling capabilities.

• PhD in Chemical Engineering, Mechanical Engineering, or related discipline with relevant thesis work.
• Demonstrated aptitude and strong background in physics‑based modeling, particularly in the areas of fluid dynamics and transport phenomena, and a broad interest in applying these skills to process development.
• Demonstrated experience with:
• Developing and applying fluid dynamics and transport phenomena modeling to simulate but not limited to multiphase flows, flows with phase change, reacting flows, or combustion
• Developing models using computational languages/platforms:
  Ansys Fluent (i.e., Fluent User‑Defined Functions), OpenFOAM, MATLAB, Python, or compiled languages (e.g., C/C++, Fortran)
• High performance computing
• Strong ability and interest to work on applications driven by abstract problems and develop creative out‑of‑the‑box solutions.
• Driven and self‑motivated.
• Strong written and oral communication skills.

• Cold flow experimentation.
• Experience simulating industrial processes at scale incorporating complexities of physics interactions such as…
