Summary:
The Senior Instrumentation & Controls (I&C) Specialist is responsible for the technical execution and oversight of instrumentation, control, and safety instrumented system (SIS) scopes across the project lifecycle from design review and FAT through construction, pre-commissioning, commissioning, startup, and early operations. The role serves as the technical authority for DCS, PLC, and SIS platforms, providing expert troubleshooting, loop and logic verification, and coordination with engineering, operations, and vendor representatives. Assignments may include refining and petrochemical revamps, modular fabrication projects, and renewable energy (hydrogen, CCUS, electrolyzers).
Responsibilities:
-
Serve as the senior I&C technical authority on assigned projects,providingexpert guidance on instrumentationselection, loop design, control narrative interpretation, and SIS architecture.
-
Review and red-line P&IDs, loop diagrams, logic diagrams, cause-and-effect matrices, instrument index, I/O lists, and SIS safety requirement specifications (SRS) during design and pre-construction phases.
-
Develop andmaintaindiscipline-level work products including commissioning procedures, loop-check protocols, function test procedures, and turnover packages.
-
Mentor junior I&C technicians, engineers, and project staff.
-
Plan and execute pre-commissioning and commissioning activities including instrument calibration, loop checking, function testing, SIS proof testing, and pre-startup safety reviews (PSSR) support.
-
Lead loop check and function test campaigns; manage punch list closure and turnover package compilation per project quality requirements.
-
Support SIS lifecycle activities including PHA/LOPA workshop participation, SIL verification reviews, SIS validation testing, bypass management, and CMMS PM setup for SIS proof testing.
-
Coordinate vendor FAT and SAT participation for control system, analyzer, and packaged equipment scopes; ensure punch items and deviations are properly captured and dispositioned.
-
Diagnose and resolve complex instrumentation, control, and SIS issues during construction, commissioning, startup, and early operations support.
-
Interpret and apply field device diagnostics; perform configuration and tuning of smart field instruments and digital communication networks.
-
Provide hands-on support for DCS, PLC, and SIS configuration changes, MOC implementation, and bypass tracking in support of commissioning and operations.
-
Enforce compliance with project specifications, governingcodesand standards (ISA, IEC, NEC/NFPA, API), and client-specific engineering standards.
-
Support hazardous area classification verification, intrinsic safety loop validation, and grounding/bonding verification activities.
-
Document all field activities, test results, deviations, and lessons learnedin accordance withthe project document management plan and CC&C procedures.
-
Champion a strong HSE culture;participatein pre-job safety briefings, JSAs, and incident investigations asrequired.
