Project Type: Data Centre Construction Location: Dublin or Limerick Package: 75,000 benefits Key responsibilities: Lead the design and coordination of high-voltage (HV) electrical systems and substations (110kV and above) for large-scale data centre and industrial projects. Develop and review detailed electrical designs, including single-line diagrams, protection and control schematics, earthing, and interconnection layouts. Perform system studies and calculations such as load flow, short-circuit analysis, protection coordination, and arc-flash studies. Prepare design documentation, technical specifications, and equipment schedules in accordance with project and regulatory requirements. Provide design input for HV substations, including transformer selection, switchgear, busbar systems, and protection relays. Coordinate with grid operators, utilities, and clients to define connection requirements and ensure full technical compliance with local grid codes. Support the development of primary and secondary substation designs, including control systems and SCADA integration. Collaborate with mechanical, civil, and low-voltage design teams to ensure full MEP and structural integration. Evaluate supplier and manufacturer technical submissions, ensuring compliance with specifications and standards. Contribute to risk assessments, method statements, and constructability reviews during design and pre-construction stages. Provide technical support during procurement, installation, testing, and commissioning phases. Mentor junior electrical engineers and contribute to the development of internal design standards and best practices. Drive continuous improvement in design quality, efficiency, and innovation within the electrical engineering function. Qualifications/Experience: Bachelor’s or Master’s degree in Electrical Engineering or equivalent discipline. Minimum 8–10 years’ experience in electrical design engineering, with a strong focus on high-voltage (110kV–400kV) substations and transmission infrastructure. Proven experience delivering HV design solutions for data centres, industrial, or utility-scale infrastructure projects. Comprehensive knowledge of IEC, EN, and local grid codes, along with experience liaising with DNOs/TSOs. Strong understanding of primary and secondary substation systems, including switchgear, transformers, busbar arrangements, and control/protection systems. Proficiency in electrical design and analysis tools such as ETAP, DIgSILENT PowerFactory, or SKM Power Tools. Experience developing and reviewing SCADA, protection, and control schemes. Familiarity with Autodesk AutoCAD, Revit, or BIM-based workflows for substation integration is an advantage. Strong technical writing and documentation skills, with attention to detail and accuracy. Excellent communication and coordination abilities, with experience working in multidisciplinary teams. Proactive, analytical, and solution-oriented mindset, able to balance design quality, constructability, and commercial efficiency. Willingness to travel occasionally across Europe for site visits, client meetings, and technical workshops.
