Sr. Principal Electrical Design Engineer

Jabil is a trusted partner for the world's top brands, offering engineering, supply chain, and manufacturing solutions. They are seeking a Sr. Principal Electrical Design Engineer to drive electrical and power solutions for high-performance computing systems, oversee design progressions, and mentor team members.

Responsibilities:

• Lead the end-to-end integration and testing of rack electrical solutions, including medium/low voltage systems (48V DC up to +/- 400V or 800V DC), uninterruptible power supplies (UPS), and power distribution units (PDUs) in varying form factors and product lines
• Participate in customer engagements and site visits to understand and document deployment constraints and gather feedback for design improvements
• Build accurate rack power budgets and model electrical capacity for both current and future high‑density server or switch configurations
• Manage relationships with electrical/power component vendors to build out a robust partner ecosystem consisting of PSUs, PDUs, bus bars, power shelves, and high voltage equipment
• Ensure all rack designs meet safety and certification requirements such as NEC/NFPA, IEEE, and UL/IEC
• Design, review, or integrate rack PDUs and power‑distribution components, including breaker configurations, metering, and load‑balancing features
• Perform detailed failure‑mode analysis, including FMEA and root‑cause investigations for electrical defects or field issues
• Define, validate, and improve factory electrical test strategies, including continuity testing, sequencing, load testing, and safety verification
• Be highly proficient in developing, updating, and interpreting electrical one‑line diagrams for rack‑level and row‑level power architectures, ensuring accurate representation of power flow, grounding, redundancy, and protection devices
• Collaborate with Architects/Compliance/Reliability and global vendors to align electrical architectures with total system design and international data center/power standards (e.g., OCP, ASHRAE, ANSI, TIA-942)
• Develop and maintain design documentation including BOMs, specifications, test plans, and engineering change orders (ECOs)
• Conduct root cause analysis and corrective actions for electrical failures or field issues
• May perform other duties and responsibilities as assigned

Requirements:

• Bachelor's Degree in Electrical Engineering, Systems Engineering, or related field is required
• Minimum of 8+ years of experience in electrical systems integration
• 4+ years of specific experience in rack-scale electrical/power design and analysis
• Strong understanding of electrical systems, integration strategies, and large-scale program management
• Familiarity with server design (EIA-310, OCP/ORV3), 48V DC busbar connections, power plugs/receptacles, and power cable routing
• Proficiency in electrical tools and simulations (e.g. AutoCAD, Ansys, PSpice, SCADA, DCIM, etc.)
• Hands-on experience with electrical safety tests such as hi-pot, ground-bond, leakage current, and continuity checks
• Writing and updating work instructions, assembly diagrams, test plans, and electrical schematics based on hands‑on build results
• Excellent English communication skills (verbal and written) with strong technical leadership capabilities
• Excellent interpersonal and communication skills
• Creative, self-motivated, accountable, and team-oriented
• Able to work independently with minimal oversight
• Capable of assessing projects, articulating risks, and developing project milestones
• Skilled in writing reports, business correspondence, and procedural guides
• Effective at presenting information and responding to management and customers
• Capable of influencing others and sharing best practices
• Familiar with stage-gate processes in project lifecycle management (PLCM)
• Ability to travel both domestically and internationally up to 30%
• Master's Degree in Electrical Engineering, Systems Engineering or related field is preferred
• Experience designing electrical power systems for data centers, telecom, or industrial power/cooling products
• Provide technical leadership by establishing long‑term electrical design standards, documentation, and best practices for rack engineering teams
• Translate one‑line diagrams into factory‑ready build documentation ensuring manufacturing teams can safely and consistently execute the electrical design during prototype builds and production ramp
• Active Professional Engineer (PE) license preferred
• Generate cable layouts to minimize EMI/EMC issues in dense computing environments
• Hands-on experience with prototype fabrication and testing; experience working with global suppliers and contract manufacturers a plus
