Senior Optimization Engineer, Carbon Capture & Sequestration

What role you will play in our team

• As the senior optimization engineer on our CCS team, you will shape the optimization foundation of a rapidly growing carbon capture and sequestration system on the U.S. Gulf Coast, influencing billions of dollars of infrastructure and operational decisions through advanced mathematical modeling.
• As part of the Low Carbon Solutions business, you will work in a dynamic, startup-like environment that leverages ExxonMobil’s scale, technical expertise, and resources to rapidly develop and deploy energy transition solutions.
• This role extends beyond mathematical model development. You will work directly with business stakeholders to apply optimization tools to real-world decisions, deepen your understanding of the CCS value chain, and help develop software products that enable optimization capabilities across the organization.   

What you will do

• Build optimization models that support network expansion decisions, CO₂ transportation planning, storage allocation, capital investment prioritization, and day-to-day operational decision making.
• Design and build optimization diagnostics, validate model formulations and solution strategies, and continuously improve model performance, scalability, maintainability, and transparency.
• Partner with stakeholders across the CCS business to apply optimization models to strategic and operational challenges, communicate recommendations, and incorporate business feedback into future model capabilities.
• Collaborate with data scientists to develop, validate, and improve surrogate models representing complex or non-linear system behavior.
• Collaborate with data and software engineers to integrate optimization models into robust, user-friendly tools that can be deployed and utilized across the CCS organization.

About you

Skills and Qualifications

• Bachelor’s, Master’s, or Ph.D. degree in Engineering, Operations Research, Applied Mathematics, Computer Science, or a related quantitative field with a strong focus on optimization.
• Five or more years of experience developing mathematical optimization solutions, including designing, implementing, and maintaining large-scale optimization models. Experience should include model formulation, performance tuning, solution validation, and translating business problems into optimization frameworks.
• Strong Python programming skills, including experience developing and maintaining optimization applications using tools such as GurobiPy, Pandas, and related scientific computing libraries.
• Demonstrated ability to independently develop, validate, and maintain complex optimization models with limited supervision.
• Strong communication skills with the ability to explain complex technical concepts to non-technical audiences and discuss detailed implementation approaches with technical stakeholders.
• Demonstrated ability to rapidly learn new business domains and adapt within a fast-paced and evolving environment.
• Strong analytical, quantitative, and problem-solving skills

Preferred Qualifications/Experience

• Experience deploying optimization models into production environments and working closely with software engineering teams to operationalize analytical solutions.
• Experience in asset-intensive, molecule-management industries such as oil and gas, chemicals, power, logistics, or related sectors.
• Prior CCS experience is not required. Candidates should demonstrate the ability to quickly learn unfamiliar domains and translate business processes and constraints into effective optimization formulations.
