This is a customer-facing, consultative engineering role that translates customer requirements into accurate, executable technical designs and ensures completed solutions align with approved specifications and engineering standards. The Sr Data Center Engineer serves as a key technical liaison among customers, project leadership, engineering teams, Integration Centers, Field Engineering, and other delivery functions. While the role is focused primarily on technical leadership and project delivery rather than traditional Field Engineering implementation or pre-sales, candidates must have strong hands-on knowledge of physical data center infrastructure. Rack-build and physical-architecture experience are key requirements, including an understanding of how data center solutions are physically assembled, cabled, integrated, tested, and validated. * Lead technical discovery to gather, validate, and document customer requirements, constraints, dependencies, and acceptance criteria. * Translate customer requirements into detailed, executable technical designs and serve as a primary technical contact throughout the deployment lifecycle. * Develop and maintain solution designs and engineering documentation, including rack designs/elevations, BOMs, cabling matrices, patch schedules, network diagrams, implementation workbooks, configuration specifications, and related technical documentation. * Apply strong knowledge of physical data center architecture, rack builds, rack integration, structured cabling, fiber/copper connectivity, equipment placement, cable routing, patching, port mappings, cross-connects, labeling, power, and grounding. * Provide technical direction and support to teams assembling, configuring, integrating, and testing customer solutions. * Review completed rack builds, configurations, test results, and technical deliverables against approved designs. * Participate in First Article Builds (FABs), Proofs of Concept (POCs), validation reviews, and other technical checkpoints as required. * Identify and resolve design discrepancies, omissions, integration issues, and technical questions discovered during build and deployment. * Lead technical closure by validating completed work against approved requirements and acceptance criteria, obtaining technical signoff where required, and ensuring final documentation accurately reflects the delivered solution. * Communicate technical status, risks, dependencies, decisions, and recommendations to customers and project leadership. * Partner closely with Project Managers, Program Managers, Field Engineering, Integration Centers, consultants, vendors, and customer technical teams throughout delivery. * Lead technical contributors through influence, establishing direction and driving accountability without direct reporting authority.
