We are seeking a hands‑on, I&E Engineer who thrives in the weeds—someone who can design, build, integrate, program, and troubleshoot complex industrial control systems from the field level up through SCADA. This role blends strong electrical aptitude with mechanical awareness and demands deep involvement in unit operations, system integration, and real‑world problem solving
.

You will be directly involved in instrumentation design, electrical systems, PLC/HMI/SCADA programming, and commissioning
, working alongside field technicians and cross‑functional teams to support both upstream and downstream processes.

This is not a desk‑only role. If you enjoy being on the floor, making connections, solving integration challenges, and seeing your designs come to life, this role is for you.

This is a high‑impact engineering role for someone who wants ownership—from concept and design through commissioning and long‑term reliability. You’ll work on diverse systems, solve complex integration challenges, and see your work directly influence operational performance.

If you’re a true I&E Heavy Hitter who enjoys rolling up your sleeves and making systems work in the real world, we want to hear from you.

• Design, program, configure, and troubleshoot PLC, HMI, and SCADA systems across a variety of platforms.
• Integrate systems using Allen‑Bradley, Siemens, and other PLC platforms
  .
• Develop and support HMI solutions (Siemens, Red Lion, Allen‑Bradley) for both upstream and downstream processes.
• Program and maintain SCADA systems
  , primarily Blue Linx
  , with a focus on reliability and usability.
• Lead design integration between Siemens HMIs and other control systems
  .

• Design, select, and specify instrumentation including sensors, analyzers, control valves, PLCs, and HMIs.
• Perform calibration, loop checks, testing, and verification of field instrumentation.
• Troubleshoot and support electrical systems including motors, MCCs, VFDs, switch gear, and local power distribution.
• Work with local power distribution (single‑phase and three‑phase) sourced from supply power panels.
• Support installation, commissioning, and startup of I&E systems and equipment.
• Develop and maintain engineering drawings and documentation, including:
  • P&IDs
  • Single‑line, multi‑line, and three‑line diagrams
  • Loop diagrams, I/O lists, and electrical schematics
  • Use AutoCAD and Solid Works to create, update, and maintain construction and as‑built drawings.
  • Maintain control system backups and configuration documentation.

• Provide hands‑on troubleshooting support alongside field technicians during testing and onsite issues.
• Conduct root cause analysis and implement corrective actions for recurring I&E issues.
• Develop and support preventive and predictive maintenance programs for critical assets.
• Support incapability and performance issues through improved instrumentation and control strategies.

• Prepare scopes of work, cost estimates, and technical documentation for I&E projects.
• Oversee contractors and vendors during electrical and instrumentation installations or upgrades.
• Collaborate with operations, maintenance, process engineering, and HSEQ teams.
• Participate in MOC processes, hazard reviews, and job safety analyses
  .
• Ensure compliance with NEC, NFPA, ISA, OSHA
  , and internal electrical safety standards.
• Provide technical training and mentorship to operators, electricians, and technicians.

• Bachelor of Science in Engineering (Electrical, Mechanical, Instrumentation, or related discipline)

• 5–7 years of hands‑on Instrumentation & Electrical engineering experience in industrial or process environments
• Direct experience in oil & gas, chemical processing, water treatment/recycling, or similar process industries

• Strong electrical…
