About the Job

Requirements

  • A degree in electrical engineering, electrotechnics, or equivalent is required.
  • Experience in project management/engineering consultancy (MOE/engineering) is required.
  • Confirmed experience on high-voltage transmission (HTB) projects is required.
  • Experience working at 225 kV is required; experience at 400 kV is preferred.
  • Experience with HTB substations and RTE grid connections is required.
  • Experience with data center or critical-infrastructure projects is required.
  • Technical English is required for international projects.
  • The role requires rigor, the ability to analyze complex systems, technical autonomy and leadership, and client-facing capability.

Responsibilities

  • Define HTB/HTA electrical architectures, including AIS/GIS substations, RTE grid-connection schemes, redundancy, and distribution schemes.
  • Perform electrical studies, including power balances, short-circuit calculations, protection selectivity and coordination, and neutral grounding arrangements.
  • Size HTB/HTA transformers, high-voltage switchgear, and protection and control systems.
  • Prepare technical documents, including calculation notes, technical specifications (CCTP), and diagrams.
  • Lead grid-connection studies, liaise with RTE, and define interfaces between grid substations and client sites.
  • Contribute to feasibility studies, grid-connection agreements, project phasing, and commissioning, while integrating grid operating constraints.
  • Review execution documents (VISA) and monitor HTB/HTA construction work on substations, connections, and transformation equipment.
  • Organize and follow factory and site acceptance tests (FAT/SAT), dielectric tests, and energization; participate in commissioning.
  • Conduct arc-flash safety studies, including incident-energy calculations and safety-distance determination; analyze fault scenarios and recommend protection settings and network architecture.
  • Determine required personal protective equipment and integrate study results into the design.
  • Act as the HTB technical reference on projects, support project management and assistance teams (MOE/AMO), and contribute to technical decisions and trade-offs.
  • Supervise engineers and drafters.
  • Design for data-center service continuity using redundant architectures (N, N+1, 2N), avoiding single points of failure and supporting fault tolerance and maintainability.
  • Manage interfaces across HTB/HTA/LV systems, generators, UPS, and battery energy storage systems (BESS), including detailed energization sequencing.
  • Support enhanced commissioning with multi-level L1–L5 tests, backup-scenario verification, and validation of final availability.
  • Address maintainability, operability, grid changeover management, and strict safety procedures.
  • Meet demanding client requirements related to schedule pressure, energy performance, contractual service-level agreements (SLAs), and availability.

Desired Qualifications

  • Experience at 400 kV is desirable.
