We also host a global business and technology center in Kuala Lumpur that provides high‑level information technology and engineering expertise to ExxonMobil’s upstream, downstream and chemical businesses worldwide.

What role will you play in the team

Operations Research Engineers function as internal consultants to support improved decision‑making by developing models using operations research methods, such as mathematical optimization and stochastic simulation. They will work in a team environment, applying their technical skills, project management, and business domain knowledge to develop technological and analytics solutions in partnership with business units to influence and improve key business decisions.

The Operations Research Engineer is expected to work with global, cross‑functional stakeholders to understand business problems (both commercially and technically), translate them into mathematical problems, and apply operations research methods to create solutions for decision support. This role will primarily work on business problems related to supply chain and commercial functions, especially for Fuels, Lubes, and Chemical products.

What will you do

• Participate in the scoping of business problems using operations research methods.
• Work with key contacts to identify and translate data requirements that represent the system and constraints to be modeled.
• Develop custom mathematical optimization and/or stochastic simulation models by applying linear programming, mixed‑integer programming, system dynamics simulation, and/or discrete event simulation.
• Proactively drive cross‑functional alignment across organizations to validate model solution quality.
• Create documentation to explain how the operations research methods are applied, and conduct reviews with senior technical professionals to ensure technical quality.
• Ensure effective and efficient pace of work by managing project timelines, coordinating project team members, and providing timely updates to stakeholders.
• Work effectively within cross‑functional, global teams (including business domain experts, product owners, decision science engineers, and IT) to design, develop, deploy, and sustain operations research‑based solutions that are scalable and of commercial‑grade quality.
