As principal power systems architect, you will own the end-to-end electrical system design of hyperscale facilities — from the high-voltage grid connection point down through the distribution network to the rack — and you will be the technical authority that holds it all together.This is not a coordination role. You will be expected to understand the work deeply enough to challenge status quo in data center electrification architecture and take them to the next levels, make defensible design decisions under uncertainty, and earn the trust of both your expert team and the external stakeholders you interface with: utilities, interconnection authorities, EPCs,
and equipment vendors.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.P
