What’s the role

The Engineer - Maintenance (Electrical) and Engineer - Maintenance (Instrumentation) roles involve end‑to‑end work planning for preventive and corrective maintenance activities across electrical and instrumentation systems in oil and gas, refinery, and petrochemical environments. Responsibilities include preparing comprehensive work packs and task lists for equipment such as switchgear, battery systems, substations, field instruments, Analyzer instruments, PLC/DCS control systems, and other related assets by studying OEM manuals, general and equipment‑specific task lists, test certificates, maintenance reports, spare part lists, and preventive maintenance strategies. Both roles require strong technical understanding—ranging from electrical wiring, circuits, transmission/operation at HV/LV voltage level and components to instrumentation and control systems—as well as familiarity with industry‑specific equipment and machinery.

They support maintenance and reliability engineers from initial response and assessment through prioritization, troubleshooting, proposing virtual technical solutions, coordinating stakeholder discussions, conducting risk assessments, ensuring QA/QC, maintaining proper documentation, and completing final job closure to enable high equipment reliability and overall plant technical availability.

What you’ll be doing

- Prepare and develop comprehensive work plans and work packs using calibration reports, maintenance reports, equipment‑specific task lists, spare part lists, drawings (P&IDs;, SLDs, schematics, loop diagrams), circuit diagrams, instrument logic, cause‑and‑effect diagrams,



equipment data sheets, and OEM O&M; manuals for field instruments, analyzer instruments, control systems, electrical switchgear, HV/LV transformers, and related E&I; equipment across various Shell operating units.
- Develop detailed maintenance plans aligned with HSSE and Protected Work Practices, covering materials, manpower, work sequencing, rental equipment, tools, and requisitioning; and build work packs with complete task descriptions, required parts/tools, estimated time, task relationships, and pre‑work preparation steps for all electrical and instrumentation scopes.
- Plan and manage SAP work orders, including building library work packs for time‑based, condition‑based, and breakdown maintenance; preparing parts and service requirements; estimating cost and duration; performing network mapping; and defining quality checkpoints for minimum assurance tasks.
- Drive work preparation quality, accuracy, and productivity by reviewing all E&I; work packages, registering/distributing work, handling additional/less work, supporting departmental integration, and optimizing work preparation processes.
- Conduct job hazard assessments and risk evaluations—including JHA, HRA, HAZID—prepare Permits to Work, determine system conditions, and identify shutdown windows or maintenance opportunities to ensure safe and efficient work execution.
- Perform diagnostics and maintenance analysis,



including first‑level damage history review, failure mode identification based on anomaly reports, CM/PM request analysis, and preparation of detailed work orders with procedures, sketches, specifications, and essential drawings.
- Ensure readiness of resources and support execution by verifying availability of special tools, materials, and services; customizing OEM work packs into site‑specific versions; and collaborating with site maintenance leads, OEMs, and vendors to update and refine work packs as required.
- Plan and anticipate mandatory spares and manpower for instruments, electrical equipment, control valves, level instruments, and damper equipment, using maintenance manuals and vendor information; and coordinate with site focal points for Preventive Maintenance Libraries and maintenance strategies across operating units.
- Utilize technical expertise and data analysis to interpret engineering drawings (P&IDs;, SLDs, PEFS, PFDs, schematics, loops, interlocks, control logic), identify and resolve process bottlenecks, maintain issue logs, and implement improvements across E&I; maintenance planning processes.

What you bring

- Degree in Engineering in Electrical, Electronics & Instrumentation / Instrumentation & Control Engineering / E&C; discipline.
- (E&I;) Minimum 2 - 10 years of hand-on field experience in Field Instrumentation, analyzer Instruments, PLCs, DCS and electrical systems and automation systems in Oil & Gas / Refinery / Petrochemicals / Equivalent Industry and in one or more of following areas.
- (Electrical) Minimum 5 plus years of a solid understanding of electrical systems, including wiring, circuits, and electrical components. Familiarity with the equipment and machinery used in the specific industry is c
