Descripción de la vacante

Hitachi Energy Ltd. in Madrid is seeking a Principal Power Systems Architect to lead end-to-end electrical design for hyperscale data centres, from HV grid connection through MV distribution to rack power.

You will drive five domain groups, engage TSOs/DSOs, sign off major study deliverables, specify system equipment, and mentor a team to deliver reliable, future‑ready electrical architectures.

Formación

• M.Sc. or Ph.D. in electrical engineering; focus on power systems is a strong differentiator.
• Minimum 15 years of industrial experience across at least three of five domains.
• Proven experience with HV grid connections, TSO engagement and grid code compliance within IEC/EU frameworks.
• Familiarity with IEC standards relevant to large power systems and hands-on experience with RMS/EMT simulation tools.

Responsabilidades

• Own the overall electrical architecture of large-scale AI data centre campuses from HV connection to rack power.
• Lead five domains: steady-state planning, dynamic studies, insulation coordination, protection and RAMS, MV/LV system design.
• Define study scope, ensure coherence, and drive grid connection strategy with TSOs/DSOs.
• Provide technical sign-off across study deliverables and equipment specifications.
• Mentor and develop the engineering team across domains.

The Opportunity

Are you ready to shape the future of energy? At Hitachi Energy, we are establishing and developing an Operation Center of Excellence in Madrid, Spain (ESOPC) within the Grid & Power Quality Solutions business in Europe (HBUEU).

We are expanding our Grid Solutions team to support the next generation of AI data centres and are looking for an experienced engineering leader to help shape this journey. As a Principal Power Systems Architect, this role is responsible for the end-to‑end electrical system design of hyperscale facilities, from the high-voltage grid connection point through the distribution network and down to the rack level. The position serves as the technical authority ensuring a coherent, reliable, and future‑ready electrical architecture across the entire system.

This is a highly technical leadership role requiring deep expertise in power systems engineering, sound engineering judgment, and the ability to challenge conventional approaches to data centre electrification. The successful candidate will work closely with specialist engineering teams and external stakeholders, including utilities, grid operators, EPCs, and equipment suppliers, to deliver robust and innovative solutions.

How You Will Make An Impact

• Own the overall electrical architecture of large-scale AI data centre campuses and ensure design coherence across all disciplines, from HV grid connection through MV distribution to AC and DC rack power.
• Define study scope and direct work across a structured team of specialist engineers covering 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. Ensure scoping and output across these groups are mutually consistent and sequenced correctly.
• Lead grid connection strategy — TSO engagement, connection application technical content, grid code compliance positioning under the applicable national grid code and EU network codes, and ancillary service obligations — with particular focus on dominant‑load HV connections at 100 MW and above.
• Provide technical sign‑off across all major study deliverables and design work.
• Drive system‑level equipment specification: HV/MV transformers, reactive compensation, BESS integration, power electronics topology, and UPS architecture — in accordance with the relevant IEC standards.
• Act as the primary technical interface with external parties — TSOs, / DSOs, grid code authorities, EPCs, independent engineers, and supplying OEMs.
• Identify and manage technical risk across the full project lifecycle, including interface risks between electrical, civil, cooling, and IT infrastructure.
• Mentor and develop the specialist engineering team, building capability across all five study domains over time.

Your background

• 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.
• Minimum 15 years of relevant industrial experience spanning at least three of the five specialist domains, with genuine familiarity across all five.
• Proven experience with HV grid connections in an IEC regulatory context, including direct TSO engagement on connection studies, grid code compliance at transmission level, and familiarity with EU network codes (RfG, DCC, HVDC) where applicable.
• Familiarity with the IEC standards landscape relevant to large power systems: IEC 60909 (short circuit), IEC 60071 (insulation coordination), IEC 61936 (HV installations), IEC 61850 (substation communication), and IEC 62271 (switchgear).
• Hands-on experience with at least two major simulation platforms across the RMS and EMT domains (e.g. PowerFactory, PSS/E, PS-CAD,), and the ability to critically review outputs from tools you do not operate yourself.
• Experience with power generation systems and distributed control architectures — including DCS/SCADA integration, governor and excitation control, and plant‑level energy management in accordance with IEC 61850 and IEC 61968/61970 — is a significant advantage.
• Comfortable working at the boundary between power systems engineering and adjacent disciplines: power electronics, data centre infrastructure, civil interfaces, and commercial constraints.
• Fluent in English; proficiency in a second language relevant to the operating region is an advantage.
