Key Responsibilities

Customer & Solution Engagement
Engage customers and project stakeholders to define electrical system requirements, load profiles, and redundancy levels (Tier I–IV).
Provide technical consultation and conceptual design solutions that align with customer capacity, uptime, and energy efficiency goals.
Support sales and solutioning teams in developing technical proposals, equipment strategies, and high-level power distribution concepts during pre-sales and tender stages.
Electrical Design Management
Lead and manage the electrical design process for data center projects, including medium-voltage (MV) and low-voltage (LV) distribution systems, UPS, switchgear, PDUs, busway, standby generators, and emergency systems.
Develop system architecture and single-line diagrams (SLDs), power flow studies, and fault-level analyses to ensure reliability and compliance.
Review and validate detailed design deliverables prepared by consultants or contractors to maintain design intent, coordination, and constructability.
Technical Leadership & Design Reviews
Provide technical leadership on electrical engineering principles, ensuring alignment with Uptime Tier standards, IEC, IEEE, and NEC requirements.
Conduct formal design reviews and technical audits at key project milestones (concept, schematic, detailed design, and IFC).
Ensure designs are optimized for cost, performance, scalability, and operational maintainability.
Compliance, Standards & Quality Control
Ensure electrical systems comply with local authority codes, international standards, and company design guidelines.
Lead initiatives to develop, maintain, and improve DayOne's electrical design standards, design manuals, and technical libraries.
Implement design QA/QC protocols to verify accuracy, completeness, and quality of deliverables.
Innovation & System Optimization
Drive research and implementation of new technologies in data center electrical systems, including modular switchgear, high-efficiency UPS, busway distribution, and renewable or hybrid power integration.
Conduct system reliability assessments (e.g., failure mode analysis) and energy efficiency optimization for power distribution systems.
Vendor & Stakeholder Coordination
Coordinate with equipment vendors and suppliers to evaluate and select electrical components based on project requirements, lifecycle cost, and technical performance.
Work closely with construction teams to ensure smooth transition from design to installation and commissioning.
Provide technical Q&A and troubleshooting support for electrical issues during construction and commissioning stages.
Documentation & Reporting
Prepare, review, and maintain technical documentation, including schematics, specifications, reports, and as-built records.
Support internal reporting on project progress, design risks, and cost-performance analysis.

Job Requirements

Education & Qualifications

Bachelor's degree or higher in Electrical Engineering or a related field.
Master's degree and/or Professional Engineer (PE) license or equivalent registration is an advantage.

Experience

Minimum 8–10 years of experience in electrical design and design management within the data center or mission-critical infrastructure sectors.
Proven experience leading electrical system design from concept to completion, with deep understanding of redundant power architectures (N, N+1, 2N) and high-availability system design.
Track record of delivering large-scale data center projects (>20 MW IT load) or comparable mission-critical facilities.

Technical Expertise

Strong proficiency in power system analysis, including load flow, short circuit, and protection coordination studies.
In-depth understanding of MV/LV distribution, UPS topologies, generator systems, earthing/bonding, and lighting and control systems.
Familiar with battery energy storage systems (BESS), renewable energy integration, and on-site generation strategies is advantageous.
Deep knowledge of NEC, IEC, IEEE, and local authority regulations applicable to electrical design and installation.

Skills & Competencies

Strong analytical and problem-solving skills, with the ability to resolve design and construction challenges effectively.
Excellent communication and stakeholder management skills, capable of articulating technical concepts to both technical and non-technical audiences.
Fluent in English (spoken and written); a second language is a plus.
Proficient in MS Office, AutoCAD, and Revit (BIM); experience with ETAP, SKM PowerTools, or similar analysis software is preferred.
Ability to work under pressure, manage multiple priorities, and deliver results in a fast-paced environment.

DayOne is proud to be an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees.
