How will you make an impact?

We are looking for a 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 high/low voltage systems (AC/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.

• Bachelor's Degree in Electrical Engineering, Systems Engineering, or related field is required

• Minimum of 7+ years of experience in electrical systems integration
• 3+ 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.

• Headquartered in Austin, TX, with a flagship facility located near The Domain and the Austin FC stadium
• Growing rapidly, with a team of more than 100 employees in Austin (500+ worldwide) and significant expansion planned through 2026
• Generated over $12 billion in FY25 revenue, driven largely by partnerships with major hyperscale customers
• Delivers cutting‑edge engineering, supply chain, and manufacturing solutions that power the world's AI infrastructure and global data center ecosystems

• Annual bonus opportunity
• Medical, dental, and vision insurance plans
• Paid time off (PTO)
• 4 weeks of paid parental leave
• 11 company-paid holidays (9 fixed holidays and 2 optional floating holidays), subject to change yearly
