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.   About Learn more about what we do in Houston  here . What role you will play in our team

As the optimization engineer for the CCS100 team, you will be responsible for the CCS optimization models at the core of our products. This includes the development, improvements and maintenance on the models. Lead in translating new requirements from the business into model constraints and objectives. Rapidly iterate on model updates to help the team achieve realistic results. Provide technical optimization support to the analysts using the product. Help debug infeasibilities and explain unexpected behavior What you will do

Work with business to understand the system constraints and incorporate them into the model. Ask detailed follow up questions to discover the real system constraints Work with the data scientists on the team to develop and improve surrogate models for the non-linear parts of the CCS system Update of existing models to incorporate multiple timescales Build out optimization diagnostic tools to support self service debugging of model inputs

Conduct simulations and experiments to validate optimization models and strategies Tuning of the Gurobi optimization parameters to improve model performance Simplification of solution algorithms to improve model sustainability Apply your model to real business problems and present results to stakeholders   About you
