The role requires deep expertise in high-voltage and low-voltage power systems, critical power infrastructure, and a thorough working knowledge of Japanese electrical codes, regulations, and utility frameworks - the essential "know-how in Japan" required to deliver compliant and reliable data centre facilities. Electrical Engineering & Design - Lead the end-to-end electrical design of data centre facilities including HV/LV power distribution, UPS systems, standby generators, automatic transfer switches (ATS), switchgear, and busbar systems. - Develop single-line diagrams, load calculations, short-circuit studies, cable schedules, earthing and lightning protection designs, and electrical equipment layouts. - Design and specify critical power systems to meet Uptime Institute Tier standards, client reliability requirements and Japanese regulatory requirements. - Conduct power quality assessments, energy efficiency analyses, and PUE optimisation reviews. - Oversee BIM/CAD deliverables and ensure drawing accuracy, coordination, and compliance with B Global Tech's design standards. Japanese Regulatory Compliance (Know-how in Japan) - Ensure all electrical designs comply with the Electricity Business Act, Building Standards Act, Fire Service Act, and relevant JIS/JEC standards. - Manage the High Voltage Electrical Work permit process and liaise with TEPCO and other regional utilities for grid connection, capacity reservations, and inspections. - Coordinate with the Electrical Safety Inspection Corporation and relevant inspection authorities for commissioning approvals. - Advise on electrical contractor licensing requirements under Japanese law and review contractor qualifications accordingly. Construction & Commissioning Support - Provide technical guidance during procurement, construction and commissioning phases; review shop drawings, RFIs, and method statements. - Witness and review factory acceptance tests (FAT) and site acceptance tests (SAT) for critical electrical equipment. - Support the preparation of O&M documentation, as-built drawings and handover packs. Collaboration & Leadership - Work closely with mechanical, structural and architecture teams across Barcelona HQ and APAC offices to ensure fully coordinated designs. - Support business development activities including technical proposals, client presentations and scope definitions. - Mentor junior engineers and contribute to building B Global Tech's engineering capability in Japan. Education & Certification - Bachelor's or Master's degree in Electrical Engineering or a closely related discipline. - Japanese professional licensure is highly desirable: First-Class Electrical Work Technician, First or Second Class Electrical Engineer, or registered Professional Engineer (Gijutsushi) in Electrical & Electronics. - Uptime Institute Accredited Tier Designer (ATD) or similar data centre certification is an advantage. Experience - 8+ years of electrical engineering experience, with a minimum of 5 years specifically in data centre, mission-critical or large-scale commercial M&E projects. - Candidates must come from a consultancy background - prior experience working within an engineering design or technical consultancy firm is a mandatory requirement. - Demonstrated experience delivering electrical designs in Japan and strong working knowledge of Japanese codes, utility processes and local market practices. - Experience with HV systems (6.6 kV and above) in Japanese data centre or industrial facilities. Technical Skills - Proficiency in electrical design and analysis tools: AutoCAD, Revit MEP / BIM, ETAP or SKM PowerTools for power system studies. - Working knowledge of Uptime Institute Tier standards, IEC, and Japanese Industrial Standards (JIS/JEC). - Strong understanding of data centre power infrastructure including 2N, N+1 and concurrent maintainability concepts. Language & Soft Skills - Business-level Japanese (spoken and written) is essential for client, authority and contractor engagement in Japan. - Professional working English required for coordination with Barcelona HQ and APAC offices. - Strong communication skills; able to present complex technical matters clearly to non-technical stakeholders.
