Role Profile:
Seeking experienced Intermediate & Senior I&E Designers to lead instrumentation and electrical design for oil & gas projects through FEED, detailed design, procurement, construction support, and commissioning. The role requires strong technical expertise in hazardous-area applications, PLC/DCS/SCADA interfaces, electrical power systems, and team leadership.
Key Responsibilities:
Lead I&E design activities across project phases (FEED, detailed design, procurement, construction support, pre-commissioning and commissioning).
Promotes safety, quality and lessons learnt for projects.
Support and provide input into the development of proposals.
Mentor junior designers/drafters and coordinate with procurement, construction and client teams.
Maintain design change control, QA/QC reviews, as-built documentation and O&M manuals.
Produce and review deliverables: P&IDs, instrument index, I/O lists, loop diagrams, single-line diagrams, cable schedules, wiring diagrams, termination matrices, junction box and panel layouts, and BOMs.
Perform electrical calculations: short-circuit, protective device coordination, load flow, voltage drop, cable sizing, motor starting, grounding/earthing and lightning protection.
Specify field instruments, analyzers, flowmeters, transmitters, control valves/actuators, RTUs/PLCs/DCS interfaces, and explosion-proof/intrinsically safe equipment.
Implement hazardous-area classification (ATEX/IECEx/NEC Class/Division) requirements and specify enclosures, purge systems and cable glands.
Develop I/O mapping, control narratives, loop diagrams and interface matrices for PLC/DCS/SCADA, including HART/Fieldbus/Modbus/Ethernet networks.
Prepare technical requisitions, evaluate vendor datasheets, review vendor drawings and support FAT/SAT activities.
Coordinate with process, mechanical, structural and civil disciplines on routing, supports and layout.
Support HAZOP, LOPA and SIL activities; recommend SIF instrumentation and participate in SIL verification/testing.
Provide construction and commissioning support: review shop drawings, respond to RFIs, witness factory tests and troubleshoot start-up issues.
In partnering with Process, prepare instrument datasheets for pressure, temperature, level, flow transmitters and actuated valves and select appropriate technology for the application.
Perform infrastructure design (wiring, cables and associated hardware) of DCS, ESD, BMS, FGS, general-purpose PLCs and analyzer systems.
Capable of designing pneumatic, hydraulic and relay controls for specific applications.
Perform panel design for the above systems; develop material specifications to support procurement activities.
Conduct vendor offer reviews and technical bid evaluations (TBE) for equipment.
Support functional safety studies including HAZOP, LOPA and SIL verification for Safety Instrumented Systems (SIS).
Work Authorization:
Applicants must be legally authorized to work in the United States. The company does not offer visa sponsorship for this role at this time.
Required Qualifications (Senior):
Minimum 8–12 years’ relevant I&E design experience in oil & gas (upstream/downstream) projects.
Strong knowledge of hazardous-area equipment selection and standards (ATEX, IECEx, NEC/Class/Division), API, IEC, ISA, IEEE.
Proven experience with PLC/DCS/SCADA interfaces, HART/Fieldbus/Modbus/Ethernet networks and instrument bus architecture.
Competence in electrical calculations (short-circuit, coordination, load flow, voltage drop), cable sizing and grounding.
Experience producing P&IDs, loop diagrams, single-line diagrams, cable schedules, panel layouts and BOMs.
Demonstrated ability to lead design reviews, manage change control and deliverables.
Intermediate / Mid-Level I&E Designer — Requirements:
3–7 years’ I&E design experience in oil & gas or related industrial projects.
Practical experience producing P&IDs, instrument index, I/O lists, loop diagrams, cable schedules and basic single-line diagrams.
Familiarity with hazardous-area concepts and equipment selection (ATEX/IECEx/NEC basics).
Working knowledge of PLC/DCS I/O mapping, HART/Modbus communication basics and control loop tagging.
Ability to perform basic electrical calculations (voltage drop, cable sizing, simple load summaries) and follow established protection coordination.
Proficient with CAD tools (AutoCAD, AutoCAD Electrical, MicroStation) and MS Office; exposure to SPI/Intergraph or ETAP advantageous.
Support senior designers in vendor data reviews, technical requisitions, RFIs, shop drawing checks and on-site commissioning assistance.
Strong communication, attention to detail and willingness to travel to project sites as required.
Preferred Qualifications:
Experience working in an EPC environment.
Brownfield and revamp project experience.
Field or construction support experience.
Experience acting as lead I&E Designer on projects.
