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 ins
