Engineer II, Instrumentation, Sweeny Refinery

Phillips 66 & YOU - Together we can fuel the future

As an Instrumentation Engineer II at Phillips 66, you’ll help design, specify, install, and improve the instrumentation systems that provide accurate, reliable measurements across refinery operations. Working with operations, maintenance, project, and engineering partners, you’ll solve instrument and analyzer problems, support field installations and commissioning, and deliver projects that improve safety, reliability, and process performance. This is an opportunity to deepen your instrumentation expertise while working independently and providing technical guidance when needed.

What You’ll Do

• Design and evaluate instrumentation solutions for pressure, flow, temperature, level, analytical, and other process measurements, including feasibility testing and validation.
• Develop and maintain instrument indexes, datasheets, specifications, P&IDs, loop diagrams, installation details, I/O documentation, test procedures, standards, and other technical deliverables.
• Troubleshoot measurement and instrument performance issues by defining problems, isolating root causes, evaluating signal and equipment conditions, recommending solutions, and verifying results.
• Support the selection, application, and installation of field instruments, analyzers, control valves, and related equipment for new and existing process units.
• Guide instrumentation installations and upgrades, and support calibration, loop checks, functional testing, commissioning, startup, and verification activities.
• Deliver small- to medium-scale instrumentation projects within established program plans, coordinating scope, schedules, resources, procurement, construction support, testing, and validation.
• Partner with operations and maintenance to improve instrument reliability, manage obsolescence, evaluate spare-parts needs, and identify opportunities to reduce recurring failures.
• Collect and analyze instrument, analyzer, and process data to identify trends, evaluate performance, and support continuous improvement and process optimization.
• Research instrumentation and analyzer technologies, define future-state improvements, support change strategies, and provide technical guidance to project stakeholders and less experienced team members.

What You’ll Bring - Required

• Legally authorized to work in the job posting country
• Bachelor’s degree
• 3 or more years of engineering experience directly related to instrumentation, analyzer systems, control systems, or related refinery/manufacturing equipment
• Willing and able to obtain a Transportation Worker Identification Credential (TWIC)
• Possess a valid driver’s license
• Must be willing and able, with or without reasonable accommodations, to comply with the following:

• • Travel up to 5%
  • Work extended hours, which may include evenings, weekends, and holidays, and perform occasional duties
  • Transport articles up to 50 pounds
  • Climb ladders and stairs up to 200 feet
  • Work safely near large, hot, high-speed machines, around chemicals and hydrocarbons under high pressure and heat, and in harsh weather conditions
  • Wear fire-retardant clothing and personal protective equipment
  • Meet respirator and face-mask fit requirements when assigned

What Makes You Stand Out - Preferred

• Master’s degree or equivalent advanced technical education in Engineering or a related field
• Bachelor of Science degree in Chemical, Electrical, Mechanical Engineering, or equivalent technical discipline
• 5 or more years of experience in the oil and gas or chemicals industry with emphasis on process instrumentation, analyzers, control valves, or instrumentation engineering
• Experience applying instrumentation for pressure, flow, temperature, level, and analytical measurements, including instrument selection, sizing, specification, and installation
• Experience developing or maintaining instrument indexes, datasheets, specifications, P&IDs, loop diagrams, I/O lists, installation details, standards, procedures, or project documentation
• Experience with Continuous Emissions Monitoring Systems (CEMS), process analyzers, and SCAQMD or EPA regulations and requirements
• Experience supporting calibration programs, loop checks, functional testing, commissioning, verification and validation, root-cause investigations, reliability improvement, or instrument obsolescence strategies
• Experience interfacing instrumentation with distributed control systems, programmable logic controllers, safety systems, or related process control platforms
• Demonstrated ability to make sound decisions in complex, non-routine situations and provide technical guidance to others
