Senior Engineer II, Research

About the role

As a Senior Engineer, Process Integrity in our Energy Research & Innovation organization, you will investigate complex technical problems and turn advanced characterization, troubleshooting, and modeling work into practical solutions that support the reliability and performance of Phillips 66's refining, midstream, and renewable fuel assets. You'll work across disciplines to lead challenging troubleshooting projects, develop improved methods, advise business partners, and build technical capability in a collaborative environment where your expertise can make a measurable impact.

Responsibilities

• Identify opportunities to apply laboratory and field testing to real operating problems; design and execute experiments and tests using appropriate methods and analytical techniques; and translate results into practical, unit-level recommendations that resolve issues and support Phillips 66 operations.
• Develop and deliver plans for significant technical support and troubleshooting efforts, managing a portfolio of projects while balancing priorities, resources, schedules, and technical risk across multiple sites and customers.
• Analyze data from laboratory, field, process, and other sources to identify trends and root causes, evaluate operational and business impacts, and translate findings into actionable recommendations that support site decisions.
• Apply advanced diagnostic methods, analytical characterization techniques, modeling, simulation, scientific software, and company-approved AI tools to investigate complex technical problems and evaluate outcomes.
• Improve troubleshooting processes, procedures, test methodologies, and tools; develop new techniques and diagnostic capabilities; and create reusable standards that strengthen the quality, consistency, and efficiency of technical support across the organization.
• Provide expert technical advice on findings, standards, procedures, and emerging integrity issues, helping sites and stakeholders take informed action across refining, midstream, and renewable businesses.
• Serve as a subject matter expert in areas such as corrosion, fouling mitigation, crude quality, renewable feed quality, or product quality; mentor colleagues and provide guidance to less experienced scientists and engineers.
• Build business cases that justify proactive investigations and investments to improve reliability and operations.
• Contribute to technical reports
