How will you make an impact?
We are seeking a highly skilled, technically authoritative and customer-facing Sr. Principal Hyperscale Rack Engineer within the Intelligent Infrastructure Segment to lead the architecture, integration, and strategic direction of advanced air and liquid-cooled server and network rack solutions for large-scale hyperscale deployments.
This role will serve as the senior technical authority responsible for translating customer requirements into scalable, manufacturable, and commercially viable rack systems.
As the Sr. Principal Hyperscale Rack Engineer , you will operate at the intersection of engineering, customer engagement, and program execution – driving end-to-end rack architecture across mechanical, power, thermal, electrical, and software domains.
Success in this role requires deep technical expertise, strong commercial acumen, and the ability to lead complex programs while influencing both internal and external stakeholders.
What will you do?
Serve as the lead architect and development manager for complex rack-level solutions, owning system-level design decisions across mechanical, electrical, power, thermal, networking, and software integration domains.
Lead customer-facing technical engagements from RFI/RFQ all the way to first hardware delivery, including design reviews, trade-off discussions, and executive-level conversations.
Translate ambiguous or evolving customer requirements into clear program frameworks, ensuring alignment between customer expectations and engineering execution.
Demonstrate strong commercial awareness by effectively managing customer expectations, pushing back when requirements introduce risk or inefficiency, and confidently addressing challenging technical and cost-related questions.
Drive cross-functional alignment across all departments (executives, engineering, supply chain, manufacturing, and program) to ensure cohesive solution development with emphasis on Bill of Materials (BOM) management and scheduling.
Own rack-level architecture including power distribution design, thermal strategies (air and liquid cooling), cable routing, serviceability, and manufacturability.
Provide deep technical guidance on rack infrastructure including PDUs, busbars, liquid cooling systems (CDUs, manifolds, QDs), airflow design, and high-density compute integration.
Oversee architecture decisions impacting performance, cost, scalability, and deployment efficiency.
Drive program execution from concept through production, ensuring schedules are clearly defined, tracked, and met.
Apply strong program management discipline: define milestones, identify risks early, escalate issues proactively, and hold cross-functional teams accountable to commitments.
Drive readiness support calls internally from initial NPI scoping to prototyping to mass production, ensuring all systems are operable together from a power, thermal, and software standpoint.
Partner with customers and internal stakeholders to continuously refine designs based on deployment feedback and operational learnings.
Collaborate with compliance and certification teams to ensure mechanical designs meet global regulatory requirements (e.g., UL, CE, ISTA, ASTM).
Mentor and guide engineers across disciplines, establishing best practices in rack system architecture and integration.
