About the Job

Requirements

  • Experience working as a design engineer for a distribution network operator or transmission system operator in extra-high-voltage systems or high-voltage/low-voltage systems.
  • Proven experience and in-depth knowledge using protection and control relay configuration software, including tools from ABB, Siemens, Schneider Electric, and GE; familiarity with setting up, parameterizing, and testing protection relays using these manufacturers’ tools is essential.
  • Working knowledge of medium-voltage/high-voltage equipment, including switchgear, transformers, protections, underground and overhead lines, and other medium-voltage/high-voltage equipment.
  • Knowledge of local regulations in Spain, Portugal, France, Italy, the United Kingdom, Germany, Poland, Greece, and Azerbaijan.
  • Strong knowledge of transmission system operator and distribution network operator technical specifications.
  • Extensive field experience deploying medium-voltage/high-voltage equipment and applying associated good-practice installation methods.
  • Experience with testing and commissioning tests for renewable installations.
  • Experience in power systems for renewable installations, including high-voltage substations and control.
  • Detailed knowledge of reactive power compensation strategies.
  • Experience in detailed electrical system design using specialized calculation software such as ETAP, DIgSILENT, CymCap, Elek, and Cableizer.
  • Familiarity with the photovoltaic industry and photovoltaic systems, including inverters, transformers, and cabling.
  • Familiarity with electrical protection calculations and earthing design for medium- and high-voltage systems.
  • Familiarity with storage system technologies and strategies for renewable applications.
  • A degree or master's degree in electrical or power engineering.
  • At least 15 years of experience in the substation design industry.
  • Fluent spoken and written English at C1 level.
  • A driving license.
  • International working experience or experience on global projects.
  • Strong interest in renewable energy.
  • Ability to prioritize workload and work autonomously, adaptably, and across multiple skill areas.
  • Ability to promote a positive working culture within the team.
  • Strong organizational and verbal and written communication skills.

Responsibilities

  • Perform calculations, studies, and reviews of technical documentation related to control, protection, and supervisory control and data acquisition systems to ensure compliance with grid connection requirements across the regions where the Grid EMEA team operates.
  • Review and comment on basic and detailed engineering for planning, tendering, construction, and commissioning stages, including as-built high-voltage engineering designs, control and protection architecture, logical diagrams, interlocking concepts, and high-voltage substation signal lists.
  • Review manufacturers’ designs of high-voltage equipment related to control and protection systems, supervisory control and data acquisition, telecommunications, control and protection equipment, relays and devices, and parameterization of relays and other medium- and high-voltage equipment.
  • Calculate high-voltage installations, protection coordination studies, alternating- and direct-current system load studies, and current- and voltage-transformer sizing.
  • Prepare high-voltage substation design deliverables, including conceptual detailed designs for requests for proposals, planning, and detailed designs for contestable works tendering in coordination with the grid project team.
  • Perform calculations and studies based on technical risks and hazard analyses identified by the grid project team.
  • Contribute to optimizing interconnection solutions, costs, deadlines, quality, and risks.
  • Support centralizing and compiling information, lessons learned, engineering knowledge, local regulations, and best practices across different regions.
  • Prepare periodic engineering status and progress reports, including internal reports, reports for engineering, procurement, and construction contractors and independent connection providers, reports for high-voltage manufacturers, and meeting minutes.
  • Report engineering activities regularly to the Head of High-Voltage Engineering for EMEA.

Desired Qualifications

  • Additional languages are a plus.
