Responsibilities:

• Plan and design physical IT infrastructure for offices, labs, manufacturing facilities, and data centers.
• Lead and support new site buildouts, office expansions and relocations, data center deployments, hardware refreshes, and infrastructure moves.
• Develop rack layouts, MDF/IDF requirements, equipment placement plans, and infrastructure bills of materials.
• Create and maintain accurate rack elevations, physical connectivity diagrams, equipment records, cable documentation, and DCIM data across office and data center environments.
• Support capacity planning across rack space, site and data center power, cooling, cabling, and equipment growth.
• Administer and improve DCIM/IPAM/CMDB platforms such as Nautobot, NetBox, Device42, or equivalent.
• Establish and maintain physical infrastructure documentation and labeling standards to ensure environments remain accurately documented throughout their lifecycle.
• Review floor plans, low-voltage drawings, vendor designs, proposals, and statements of work.
• Coordinate with architects, contractors, colocation providers, carriers, OEMs, and field-service vendors.
• Partner with Network, Systems, and Cloud Engineering teams to ensure site and data center infrastructure supports compute, storage, connectivity, wireless, security, hybrid connectivity, and public cloud requirements.
• Identify capacity constraints, documentation gaps, and opportunities to improve infrastructure standards and processes.
• Provide technical guidance to junior engineers and support teams as needed.

Required Qualifications:

• 5+ years of experience in data center, enterprise site, or physical IT infrastructure engineering.
• Experience designing and supporting infrastructure across offices, data centers, labs, or similar enterprise environments.
• Strong experience creating and maintaining rack elevations, physical infrastructure diagrams, cabling documentation, equipment layouts, and infrastructure records.
• Strong knowledge of rack design, structured copper/fiber cabling, equipment placement, and physical infrastructure standards.
• Strong working knowledge of data center and site power, including A/B power, UPS/PDU systems, circuit capacity, equipment power draw, redundancy, and related cooling/airflow considerations.
• Experience designing MDF/IDF environments and sizing infrastructure for new or expanding facilities.
• Experience with DCIM/IPAM/CMDB platforms such as Nautobot, NetBox, Device42, Sunbird, or similar.
• Working understanding of enterprise networking, including switching, wireless, WAN connectivity, and carrier services.
• Ability to interpret architectural drawings, floor plans, low-voltage designs, and equipment specifications.
• Experience working with colocation providers, low-voltage contractors, carriers, and technology vendors.
• Strong technical documentation, communication, and organizational skills.
• Ability to independently execute infrastructure projects from planning through deployment.
• Ability to travel periodically for site and data center deployments.

Preferred Qualifications:

• Experience supporting a geographically distributed or rapidly growing enterprise.
• Experience across offices, engineering labs, manufacturing environments, and colocation data centers.
• Hands-on experience with Nautobot or NetBox for DCIM, IPAM, rack elevations, circuits, and infrastructure documentation.
• Experience supporting data center migrations, expansions, or greenfield site deployments.
• Familiarity with hybrid infrastructure and public cloud platforms such as AWS and Azure, including connectivity between enterprise sites, data centers, and cloud environments.
• Familiarity with infrastructure from vendors such as Juniper, Cisco, Palo Alto Networks, Dell, APC, or Vertiv.
• Experience developing infrastructure BOMs, cost estimates, lifecycle plans, and capacity forecasts.
• Experience using APIs, scripting, or automation to improve DCIM and infrastructure lifecycle management.
• Experience within aerospace, defense, manufacturing, or other regulated environments.
• Relevant certifications such as BICSI, CDCP, CCNA/CCNP, or equivalent.
