Lead Instrumentation and Control Engineer

Role & responsibilities

Key Responsibilities

Design & Engineering Leadership

• Lead preparation and review of control philosophy, instrument index, I/O list, cause & effect diagrams, control narratives, and instrument datasheets across all disciplines and product lines.
• Own DCS/PLC/SCADA/ICCP architecture, network topology, and control system sizing for electrolyser, synthesis loop, and BOP packages.
• Define hazardous area classification requirements in coordination with PS/EE and ensure instrument selection (Ex-rated transmitters, control valves, analysers) complies with area classification.
• Review and approve field instrument specifications, control valve sizing/selection, and analyser system selection (H, O, NH, CO, purity analysers) in coordination with PE.
• Develop and review junction box/marshalling cabinet layouts, cable schedules, and instrument installation details jointly with EE and CV.
• Define the electrolyser power/control system boundary (rectifier control interface, stack protection interfaces) jointly with EE.

Process Safety & SIS

• Lead SIL determination studies (LOPA) with PS, and own SIL verification / PFDavg calculations for Safety Instrumented Functions (SIFs) up to project completion.
• Participate as the C&I discipline lead in HAZOP, HAZID, and SIL workshops; ensure safeguards identified are translated correctly into logic, interlocks, and SIS architecture.
• Ensure Safety Instrumented System (SIS) design, proof-test intervals, and bypass/override philosophy comply with IEC 61511/61508 and client requirements.
• Own cybersecurity (IEC 62443) requirements for control system architecture in coordination with client IT/OT policies.

Vendor, Procurement & Construction Support

• Review vendor/package unit (electrolyser, compressor, rectifier, reformer, synthesis loop) control and instrumentation scope for interface completeness and specification compliance.
• Lead technical bid evaluation (TBE) for DCS/PLC/SCADA/SIS packages and major instrumentation, and support FAT/SAT and instrument loop checks at vendor works and site.
• Provide construction and commissioning support: instrument installation checks, loop checks, control narrative validation, and pre-commissioning punch-list closure.

Team & Coordination

• Supervise and mentor C&I engineers/designers within the discipline; review deliverables for technical adequacy prior to inter-discipline issue.
• Coordinate proactively with PE, EE, PS, PIPE, CV and PROP desks per the defined interface matrix; flag conflicts early rather than resolving them unilaterally.
• Support PROP desk with C&I scope definition, MTO, and cost basis inputs during proposal stage.
• Maintain discipline document register, ensure timely issue of deliverables per project schedule (IDC/IFR/IFC).
