In this role, you will be the technical lead for designing, installing, and optimizing our automated monitoring systems, ensuring they operate at peak efficiency and safety. You will bridge the gap between hardware sensors and enterprise-level software, working with cross-functional teams to integrate new technologies into our existing production environment. If you are passionate about process control, instrument loop integrity, and industrial automation, we invite you to help us elevate our engineering standards.

Key highlights

  • Design and calibrate sophisticated measurement and control systems including pressure, flow, level, and temperature transmitters within industrial processing units.
  • Program, configure, and maintain PLC and DCS hardware to ensure accurate process automation and reliable signal processing across the facility.
  • Perform diagnostic testing and loop tuning to optimize PID control performance, directly reducing process variability and increasing production throughput.
  • Conduct regular safety audits and functional testing of Emergency Shutdown Systems (ESD) to verify system integrity and adherence to plant safety protocols.

What is a Instrumentation Engineer?

An Instrumentation Engineer is a specialized professional responsible for the design, configuration, and maintenance of the measurement and control systems that govern industrial processes. By applying advanced control theory and systems engineering, an Instrumentation Engineer ensures that parameters like pressure, flow, temperature, and level are precisely monitored and regulated. Their expertise in DCS, PLC, and SCADA architecture is vital for maintaining plant stability, adhering to strict safety protocols, and driving operational excellence in complex engineering environments.

What does a Instrumentation Engineer do?

An Instrumentation Engineer typically manages the full lifecycle of field devices and control loops, from the initial specification of transmitters and valves to the calibration and troubleshooting of automated systems. Daily work involves configuring PLCs (Programmable Logic Controllers), refining PID control loops, and ensuring compliance with industry standards like ISA or IEC 61511. They collaborate closely with electrical engineers, maintenance technicians, and operations teams to minimize downtime, conduct root-cause analysis on control system failures, and execute seamless system upgrades during facility turnarounds.

Key responsibilities

  • Design and calibrate sophisticated measurement and control systems including pressure, flow, level, and temperature transmitters within industrial processing units.
  • Program, configure, and maintain PLC and DCS hardware to ensure accurate process automation and reliable signal processing across the facility.
  • Perform diagnostic testing and loop tuning to optimize PID control performance, directly reducing process variability and increasing production throughput.
  • Create and update technical documentation, including P&IDs, instrument loop diagrams, and cause-and-effect matrices for regulatory and maintenance compliance.
  • Lead the root-cause analysis process for instrumentation-related equipment failures, implementing long-term corrective actions to prevent recurrence and improve system stability.
  • Collaborate with procurement and vendor teams to evaluate, specify, and purchase high-precision instrumentation components for capital and maintenance projects.
  • Oversee the installation and commissioning of field devices, ensuring all work meets NEC and ISA standards for hazardous and non-hazardous environments.
  • Conduct regular safety audits and functional testing of Emergency Shutdown Systems (ESD) to verify system integrity and adherence to plant safety protocols.

Requirements and skills

  • Bachelor of Science in Electrical Engineering, Chemical Engineering, or a related field with a strong focus on automation and control.
  • 5+ years of hands-on experience working with industrial instrumentation, control valves, and fieldbus communication protocols like HART or Foundation Fieldbus.
  • Demonstrated expertise in configuring major DCS/PLC platforms such as Emerson DeltaV, Siemens PCS7, Rockwell Automation, or Honeywell Experion.
  • In-depth knowledge of international process safety standards, including IEC 61511 and functional safety management practices for hazardous areas.
  • Proven ability to read and interpret complex engineering schematics, including P&IDs, electrical wiring diagrams, and loop drawings.
  • Professional Engineer (PE) license or ISA Certified Automation Professional (CAP) certification is highly preferred for senior-level technical advancement.
  • Advanced troubleshooting skills using digital multimeters, signal calibrators, and diagnostic software to resolve complex field signal issues.
  • Strong technical reporting ability, with experience presenting complex system performance data to non-technical stakeholders and management teams.
