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 s
