Senior Electrical Design Manager

Senior Electrical Design Manager   Location - United Kingdom   Role Summary   As Senior Manager, Electrical Design, you will act as a senior electrical technical authority within STACK Infrastructure's EMEA Design & Engineering function. You will define, govern and continuously improve STACK's electrical engineering standards, helping to ensure consistent delivery of the European Reference Design across regions. Working at platform level, you will shape electrical resilience, capacity modelling, grid interface strategy, power distribution architecture and energy performance alignment across mission-critical data centre developments. This is a high-impact role for an experienced electrical design leader who can balance technical excellence, commercial judgement and future-ready thinking for hyperscale environments.   Key Responsibilities   - Own and maintain the electrical architecture within STACK's European Reference Design, including utility interface, HV/LV configuration, generator strategy, UPS architecture and modular power building block standards. - Define and govern electrical resilience models, ensuring power distribution standards remain scalable, consistent and aligned to customer, operational and investment requirements. - Validate capacity modelling assumptions, including MVA to MW IT conversion, load growth, diversity assumptions and partial versus full build-out scenarios. - Provide senior technical oversight at design stage gates, reviewing and challenging consultant designs for compliance, resilience integrity, constructability, maintainability and client requirements. - Shape platform-level grid and infrastructure strategy, including utility connection configuration, on-site substations, dual-feed resilience positioning, generator capacity and autonomy assumptions. - Support technical due diligence and early feasibility activity by assessing power availability, infrastructure risks and abnormal assumptions before underwriting or investment decisions. - Approve structured deviations from electrical standards and lead peer reviews for high-risk or high-complexity schemes across the EMEA portfolio. - Develop the roadmap for future electrical requirements, including higher rack densities, AI-driven load profiles, liquid cooling implications, energy efficiency evolution and alternative generation technologies where relevant. - Partner with commercial, development, delivery and engineering teams to evaluate CapEx drivers, specification changes, yield opportunities and investor-level technical risk. - Develop and maintain electrical engineering standards, technical guidance, Basis of Design inputs, QA checklists and peer review frameworks, ensuring consistency across regions.   What You'll Bring   - Significant experience in mission-critical, hyperscale data centre or similarly complex electrical engineering environments. - Deep technical expertise across MV/LV distribution systems, generator and…
