Senior Network Architect

Job Profile Summary

Responsible for the strategic architecture, design, and technical direction of Rackspace's global data center and wide area network (WAN) infrastructure, with a primary focus on healthcare customer environments. Serves as the senior technical authority for data center fabric and WAN transport, including the high-bandwidth, low-latency network underlay required to support high-performance compute (HPC) and other data-intensive workloads. Translates healthcare business, clinical, and regulatory requirements into scalable, resilient, and secure network architectures. Acts as a liaison with vendors and third-party providers and partners closely with engineering, security, and customer teams to guide the network's strategic direction across highly available, compliance-driven healthcare infrastructure. This is a network architecture role focused on the connectivity fabric that delivers bandwidth and throughput to compute and storage platforms, not on designing or administering the HPC compute clusters themselves.

• Develops automation and infrastructure-as-code practices (Python, Ansible, or equivalent) to standardize provisioning, validation, and change management across the fabric

• Plans and executes network changes around clinical change-freeze windows and blackout periods (e.g., surgical schedules, EHR go-lives), coordinating timing with hospital operations to avoid disruption to patient-care systems

• Researches, evaluates, and recommends emerging data center, WAN, and HPC networking technologies and vendors based on performance, scalability, and business value

• Leads implementation planning and peer design reviews for major infrastructure initiatives, including new data center builds, fabric refreshes, and WAN transport migrations

• Creates and maintains architecture documentation, low-level and high-level design (LLD/HLD) artifacts, network diagrams, and standard operating procedures

• Mentors and provides technical guidance to network engineers and architects across the organization

• Contributes to disaster recovery and business continuity planning for data center and WAN environments, with attention to the uptime and failover requirements of clinical and patient-care systems

• Designs network architecture to support healthcare-specific workloads, including EHR/EMR platforms (e.g., Epic, Cerner), PACS/medical imaging, HL7/FHIR integration engines, and connected medical devices, as well as life-safety network domains such as nurse call systems, physician paging, and emergency communication networks
