How will you make an impact?

• We are looking for a Sr. Principal Electrical Rack Engineer within the Intelligent Infrastructure Segment to drive electrical and power solutions for high-performance computing systems.
• As a Principal Engineer, you will be expected to demonstrate a level of expertise in a particular area that matches or exceeds the expertise of customers.
• You will consult on system architecture, assess technical requirements and competencies needed during quoting and oversee design progressions during product developments. 
• You will mentor and lead others in the organization to build team members design capability.
• Collaboration with cross-functional teams, customers, and global vendors is essential to align electrical architecture with overall system design and international standards.

What will you do?

• 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.
