Senior Electrical Engineer – Data Centre (Japan)

B Global Tech is a specialist consultancy delivering design, architecture, and Mechanical & Electrical (M&E) engineering for mission-critical data centre facilities. Headquartered in Barcelona, with offices in Singapore, Malaysia, Thailand, and a newly established office in Japan. As one of our founding hires in Japan, the Senior Electrical Engineer will serve as the technical authority for all electrical engineering aspects of data centre projects in the Japanese market. 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.
