E&I Decarbonization Engineer — CCGT/CCUS at Marquise Energy Limited

Job Summary

• We are seeking a qualified and experienced E&I Decarbonization Engineer/Lead to drive electrical/mechanical and instrumentation initiatives focused on reducing emissions and improving efficiency across our Combined Cycle Gas Turbine (CCGT), Carbon Capture Utilisation and Storage, including retrofit, electrification, and general decarbonization of the gas turbine, HRSG, and steam turbine systems.
• Assess, design, and implementation of electrical/mechancical and instrumentation solutions to reduce emissions and improve efficiency of the Combined Cycle Gas Turbine (CCGT), , spanning the gas turbine (GT), Heat Recovery Steam Generator (HRSG), and steam turbine (ST) trains — including retrofit/upgrade, electrification alternatives, and general decarbonization of plant power generation.

Key Responsibilities

• Assess existing CCGT plant performance, heat rate, emissions profile, and cycle efficiency (GT, HRSG, ST) to identify decarbonization opportunities
• Lead engineering studies for CCGT decarbonization options, including:
  • Retrofit/upgrade of gas turbines for improved fuel efficiency and lower NOx/CO2 emissions
  • Optimization of HRSG and steam cycle performance to maximize combined-cycle efficiency
  • Hydrogen/gas-blend firing feasibility for the gas turbine train
  • Hybridization with renewable power (solar/wind) or battery storage to reduce run-hours/peaking load
  • Carbon capture retrofit-readiness (instrumentation and control interfaces) for the CCGT flue gas path
  • Electrification/grid-tie alternatives to reduce reliance on on-site CCGT generation
• Design and specify instrumentation and control systems for emissions monitoring across the CCGT train (NOx, CO2, methane slip, stack CEMS)
• Conduct feasibility and cost-benefit studies comparing retrofit, hybrid, and full electrification options for the CCGT plant
• Ensure E&I designs for CCGT decarbonization comply with relevant codes and standards (IEC, IEEE, API, NEC, NFPA) and environmental regulations
• Coordinate with process, mechanical, rotating equipment, and HSE teams to integrate decarbonization initiatives into overall CCGT plant engineering
• Prepare technical documentation, specifications, and datasheets for E&I decarbonization packages related to the CCGT plant
• Provide technical input for tenders, feasibility reports, and client submissions related to CCGT emissions-reduction projects
• Monitor emerging technologies relevant to CCGT decarbonization (hydrogen-blend turbines, carbon capture, digital twin/advanced control systems)
• Support commissioning, testing, and performance verification of retrofitted or newly installed CCGT E&I systems

Requirements

• Bachelor's degree in Electrical/MechanicalEngineering, Instrumentation & Control Engineering, or related discipline (Master's an advantage)
• Professional registration/certification (COREN, IEEE, or equivalent) preferred
• 8–10 years' E&I engineering experience in power generation or oil & gas, with demonstrable involvement in Combined Cycle Gas Turbine (CCGT) plants and/or decarbonization projects
• Strong knowledge of CCGT electrical/control systems (GT, HRSG, ST train), power system integration, and relevant international codes and standards
• Familiarity with emissions monitoring technologies (NOx, CO2, methane, CEMS) and carbon accounting for combined-cycle power plants
• Experience with E&I design software/tools (e.g., ETAP, AutoCAD Electrical, SPI, or equivalent)
• Strong analytical, report-writing, and stakeholder coordination skills

Desirable:

• Prior experience on Carbon Capture Utilisation and Storage and CCGT retrofit, hybridization, or mechanicalprojects
• Knowledge of hydrogen-blend firing, solar,wind,geothermal, and/or renewable/battery hybrid integration/system with combined-cycle plants
• Exposure to regulatory frameworks for power generation emissions reporting (e.g., NUPRC, EPA, or equivalent local bodies).
