Jabil has an exciting opportunity for a highly experienced and technically proficientPrincipal Electrical Engineerto engage in thedesign, fabrication, and integrationof electrical systems fordata center power and cooling products, as well asfactory enablement projects. This role includes full-stack electrical design fromgenerator systemstoAI rack integration zones, with a focus onPDUs, UPS systems,MV/HV power distribution,phased power infrastructure, andcontrols architecture. The ideal candidate will bring deep technical expertise and a passion for delivering scalable, reliable, and compliant infrastructure solutions. The Sr. Principal Electrical Integration Engineer will manage and oversee the electrical systems essential for the data center, energy storage systems, and HVAC applications. This role will involve developing specifications, selecting key components, routing wires and cables, establishing connections, and transitioning design to manufacturing. Furthermore, the position includes leading test process implementation and ensuring equipment alignment to maintain the highest standards of operational excellence and reliability. What will you do? Product & System Design : Knowledge ofhigh-efficiency power conversionandpoint-of-load regulationfor AI/ML server racks (BBU, rPDU). Understanding ofrack power zoning, load balancing, and redundancy strategies for tiered compute workloads. Ensure electrical systems are properly integrated into fabricated enclosures and structural assemblies. Lead the electrical design and integration ofUPS systems, power conversion units, and safety interlocks. Develop and maintainsingle-line and three-line diagramsfor power distribution systems, ensuring clarity, accuracy, and compliance with NEC, IEEE, and UL standards. Design and validatethree-phase power systems, including load balancing, fault protection, and redundancy strategies for high-availability environments. Engineer and integratemedium-voltage (MV)andhigh-voltage (HV)power distribution components such as switchgear, transformers, busways, and protective relays. Specify and qualify electrical components including circuit breakers, contactors, CTs/PTs, surge protection devices, isolation switches for MV/HV applications and the design and development of wiring harnesses Factory & Facility Integration : Design end-to-endelectrical distribution systems fromgenerator and utility interfacetoAI rack integration zones. Coordinate with cross functional teams to ensure electrical infrastructure aligns with facility layout, safety codes, and operational requirements. Plan and implementpower redundancy,load segmentation, andscalable distribution architecturesto support high-density compute environments. Ensure proper grounding, EMI shielding, and thermal management across all facility-level electrical systems. Fabrication & Implementation : Define fabrication processes including panel building, cable routing, and system integration, ensuring manufacturability and serviceability. Perform electrical load calculations, short-circuit analysis, arc flash studies, and thermal modeling using tools such as ETAP, SKM PowerTools, or EasyPower. Lead design reviews, risk assessments, and validation testing to ensure compliance with UL, IEC, NEC, CE, RoHS, and REACH standards. Interface with suppliers and customers resolve fabrication and quality issues, and ensure adherence to specifications. Support prototype builds, field deployments, and customer engagements to gather feedback and refine designs. Controls Architecture : Develop and implementelectrical controls architecturefor power and cooling systems, including PLCs, SCADA integration, and remote monitoring capabilities. Define control logic, sensor integration, and communication protocols (e.g., Modbus, BACnet, SNMP) for intelligent power and cooling management. Collaborate with software and automation teams to ensure seamless integration of control systems with facility and product-level infrastructure. Validate control systems through simulation, testing, and commissioning to ensure reliability, safety, and responsiveness. Leadership & Documentation : Develop and maintain engineering documentation including BOMs, test procedures, and engineering change orders (ECOs). Mentor junior engineers and provide technical leadership across cross-functional teams. Drive continuous improvement initiatives focused on cost reduction, design for manufacturability (DFM), and product scalability How will you get here? Education : Bachelors Degree in Electrical Engineering or related engineering discipline Experience : 8 years of experience in electrical design and fabrication, with a focus on data center or industrial power systems Proficiency in ECAD tools (e.g., AutoCAD Electrical, EPLAN, SolidWorks Electrical) and integration with mechanical CAD platforms Strong understanding of MV/HV power distribution, lithium-ion UPS systems, and three-phase electrical infrastructure Experience with electrical analysis tools (e.g., ETAP, SKM PowerTools, EasyPower) Proven experience in facility-level electrical design and construction support and Excellent leadership, communication, and cross-functional collaboration skills Knowledge, Skills, Abilities: Excellent interpersonal and communication skills Creative, self-motivated, accountable, and team-oriented Able to work independently with minimal oversight as part of a global team Proficient in reading, analyzing, and interpreting general business publications, professional journals, technical procedures, and government regulations Skilled in writing reports, business correspondence, and procedural guides Effective at presenting information and responding to management, clients, and public queries Capable of influencing others and sharing best practices while mentoring less experienced engineers Capable of assessing projects, articulating risks, and developing project milestones Familiar with stage-gate processes in project lifecycle management (PLCM) Excellent problem-solving skills and attention to detail Preferred Qualifications: Masters Degree in Electrical Engineering Active Professional Engineer (PE) license Experience with data center infrastructure: UPS systems, switchgear, CRAC units, and PDUs Familiarity with global compliance standards: UL, CE, RoHS, REACH, and IEEE.
