What role you will play in our team

As a Process Development and Scale-Up Engineer, you will play a critical role in translating innovative process concepts into commercially viable technologies. You will lead efforts to identify, evaluate, and develop process configurations aligned with business strategy, and guide scale-up activities.

This role requires a strong foundation in unit operations and reactor design, with an emphasis on practical problem-solving and troubleshooting. You will work closely with cross-functional teams to integrate new technologies into existing operations, assess commercial feasibility, and develop robust scale-up strategies using tools such as advanced modeling, pilot plant experimentation, and scaling data to reduce technical risks needed to ensure successful commercialization.

This posting is open to both recent PhD graduates and experienced hires. While recent graduates are encouraged to apply, experienced hires will be expected to have had process scale-up and troubleshooting roles, particularly in pilot plant operations and reactor systems, and to provide examples when they have leveraged both technical depth and hands-on experience to drive a commercial process development forward.


Come be part of the team, with opportunities at our Spring, Texas or Baytown, Texas locations

What you will do

Primary job functions include one or more of the following:

• Identify and screen new process concepts to meet future business needs. Develop options to ensure advantage of technology based on understanding of ExxonMobil and industry wide strategic opportunities

• Identify and execute methodology to assess commercial feasibility of the concept before carrying into development
  
  
• Determine key parameters for process scale-up to commercial volumes from the pilot or demo scale. Integrate scale-up and overall development strategy for high complexity developments
  
  
• Establish and execute experimental and/or modeling plans (including building and leveraging appropriate tools) to address critical technical uncertainties in the technology commercialization
  
  
• Identify and define key process/plant integration issues. Develop plans to address through interfaces with partner projects and/or engineering organization
  
  
• Optimize process consistent with business/program objectives
  
  
• Influence and guide product specification setting
  
  
• Actively seek out and engage third parties where they provide competitive advantage as part of the development
