Site DCS Engineer (ICSS / PLC / DCS)

Qualifications: Degree in Automation, Instrumentation, Control Engineering or equivalent. • 8+ years experience in DCS/ICSS/PLC engineering and execution on major oil & gas / LNG projects. • Strong knowledge of: o DCS/PCS systems o ESD/SIS and F&G systems o Package PLCs o Industrial communication protocols o Safety lifecycle, HAZOP, LOPA o GS/CR referential • Experience with large EPC contractors and multidisciplinary project execution. • Strong HSE culture and familiarity with site construction and commissioning workflows. • Fluent in English; French or Portuguese is an advantage. • Ability to work in a multicultural, remote environment with high autonomy and adaptability. Duties: 1. Technical Support (DCS / ICSS / PLC) • Ensure compliance with engineering specifications, project requirements, applicable referential, and international standards. • Review and validate ICSS/DCS/PLC documentation: architecture, I/O lists, logic diagrams, C&E matrices, network topologies, cybersecurity requirements. • Support resolution of design inconsistencies and missing information, coordinating with engineering centers (Milan, London if applicable) and EPC engineering teams. • Participate in P&ID reviews, HAZOP, Process Safety assessments, and safety review meetings if applicable • Contribute to design improvements regarding operability, maintainability, and reliability of control and safety systems. 2. Construction Support • Support installation of all DCS/ICSS equipment: cabinets, marshalling panels, safety logic solvers, field termination boxes, controllers, servers, networks, workstations, F&G panels, PLC cabinets, junction boxes, etc. • Review ITPs, method statements, inspection reports, and ensure conformity with engineering deliverables. • Participate in walkdowns, inspections, and tests (continuity, insulation, loop checks, Ex inspections). • Ensure preservation, storage, and handling of sensitive control equipment throughout construction. • Avoid contractor standby by providing timely responses to site queries (TQs), deviations, NCRs, and technical troubleshooting. 3. Pre‑commissioning / Commissioning Assistance • Support preparation, review, and implementation of pre‑commissioning and commissioning procedures for ICSS/DCS/PLC systems. • Participate in SATs for DCS/ESD/F&G and package PLC systems. • Witness key tests: o I/O loop checks o Logic testing (ESD, F&G, permissives/interlocks) o Sequence tests o System performance tests o Network redundancy checks o Package PLC–ICSS integration tests • Contribute to precomnissioning tracking system, punchlist management, and technical dossiers "as‑commissioned". • Support start‑up sequence readiness with commissioning and operations teams. 4. Package PLC & Vendor Coordination • Coordinate with package vendors (compressors, generators, HVAC, pumps, analyzers) for PLC integration into the ICSS. • Validate communication interfaces (Modbus TCP/IP, OPC, hardwired I/O, serial links). • Support vendor troubleshooting and on-site interventions. • Ensure cybersecurity (access control, antivirus, USB control, configuration management). 5. Interface Management • Coordinate interfaces between: Process – Mechanical – Electrical – Instrumentation – Telecom – Subsea – Marine – Commissioning – Operations. • Ensure all subsea/onshore DCS/ICSS interface requirements are correctly implemented. • Support integration of EMCS, EMS, SCS (Subsea Control System), analyzers, meterings, HVAC control, telecoms, and safety systems. 6. HSE and Quality Compliance • Ensure compliance with Project HSE standards; promote safety culture at site level. • Apply LOTO, PTW, electrical isolation, and safe control system intervention practices. • Report unsafe acts and conditions; support technical HSE audits and reviews. • Ensure construction and commissioning activities meet project quality requirements. 7. Reporting & Documentation • Report discipline progress, risks, technical issues, and priorities to the E&I Lead. • Ensure documentation is kept updated: as‑built drawings, loop folders, logic diagrams, network drawings, system configurations. • Support MC, pre‑commissioning, and commissioning dossier compilation and turnover.
