Principal Power Systems Architect - AI Data Centre Grid Solutions

About the role

HITACHI ENERGY SPAIN is expanding its Grid Solutions team to support the next generation of AI data centres and is looking for an experienced engineering leader as Principal Power Systems Architect. The role covers end-to-end electrical system design of hyperscale facilities, from the high-voltage grid connection point through the distribution network down to the rack level, and acts as the technical authority for a coherent, reliable and future-ready electrical architecture. It is a full-time, on-site position in Madrid.

Key responsibilities

• Own the overall electrical architecture of large-scale AI data centre campuses, from HV grid connection through MV distribution to AC and DC rack power.
• Define study scope and direct a team of specialist engineers across five domains: steady-state network planning and power quality, dynamic studies, stability and grid code compliance, electromagnetic transient and insulation coordination, protection, RAMS and asset reliability, and MV/LV system design and P&C.
• Lead grid connection strategy, including TSO engagement, connection applications, grid code compliance under national and EU network codes, and ancillary service obligations, with a focus on dominant-load HV connections of 100 MW and above.
• Provide technical sign-off on major study deliverables and design work, and drive equipment specification (transformers, reactive compensation, BESS, power electronics, UPS) in line with IEC standards.
• Act as the main technical interface with TSOs, DSOs, grid code authorities, EPCs, independent engineers and OEMs, and identify and manage technical risk across the project lifecycle.
• Mentor and develop the specialist engineering team.

Required profile

• M.Sc. or Ph.D. in electrical engineering with a focus on power systems; a thesis in grid dynamics, power electronics or HV system design is a strong differentiator.
• At least 15 years of relevant industrial experience spanning at least three of the five specialist domains, with familiarity across all five.
• Proven experience with HV grid connections in an IEC regulatory context, including direct TSO engagement and grid code compliance at transmission level, and familiarity with EU network codes (RfG, DCC, HVDC).
• Fluent English; a second language relevant to the region is an advantage.

Required skills

• Familiarity with IEC standards such as IEC 60909, IEC 60071, IEC 61936, IEC 61850 and IEC 62271.
• Hands-on experience with at least two major simulation platforms in RMS and EMT domains (e.g. PowerFactory, PSS/E, PS-CAD).
• Experience with power generation systems and distributed control architectures (DCS/SCADA, governor and excitation control, energy management) is a significant advantage.
