• Conduct daily technical surveillance of your assigned unit(s), ensuring operation within defined safety and environmental limits.

• Develop and implement process improvement plans to increase yield, improve product quality, reduce energy consumption, and minimize flaring/emissions.

• Perform engineering calculations (heat and material balances, hydraulics, equipment sizing) to validate performance and support modification proposals.

2. Technical Support & Troubleshooting

• Serve as the first point of contact for complex operational issues, providing real-time engineering support to console operators and field technicians.

• Lead or participate in root cause failure analyses (RCFA) for process upsets, equipment failures, or quality incidents.

• Develop operating guidelines and procedure updates to incorporate lessons learned and new best practices.

• Support turnaround and shutdown planning by identifying critical inspections, catalyst changeout strategies, and equipment cleaning requirements.

3. Safety, Reliability & Environmental Stewardship

• Champion Process Safety Management (PSM) elements for your area, including participation in Process Hazard Analyses (PHA), Management of Change (MOC) reviews, and Pre-Startup Safety Reviews (PSSR).

• Ensure compliance with all environmental permits (air, water, waste) through monitoring, reporting, and implementing control strategies.

• Analyze equipment performance trends to predict failures and recommend preventive maintenance strategies that enhance reliability.

• Conduct risk assessments for proposed operational changes or temporary deviations.

4. Project Development & Economic Analysis

• Develop scopes and justification for capital projects, from small reliability improvements to multi-million dollar efficiency upgrades.

• Create conceptual designs and collaborate with project engineers to develop detailed engineering packages.

• Perform economic evaluations (NPV, IRR) to prioritize improvement opportunities and justify capital expenditures.

• Provide process engineering input during project commissioning and startup.

5. Mentorship & Knowledge Sharing

• Document and share technical knowledge within the global ExxonMobil engineering community.

• Mentor new engineers and co-op students.

• Participate in global engineering networks to leverage best practices from other sites.
