Network Service Design Manager

We invite you to join NTT DATA North America as a Network Service Design Manager
. The role will be based in Baltimore, Maryland (or Annapolis, Maryland for some opportunities) and will lead a large‑scale network modernization program serving public‑sector clients across Maryland.

As the Service Design Manager, you will be a technical leader for a large‑scale network modernization program. You will manage Service Catalogue Management, Service Level Management, Capacity Management, Availability Management, IT Service Continuity Management, Information Security, and Supplier Management. You will define the target architecture, produce HLD/LLD artifacts, govern standards and patterns, and lead end‑to‑end technical delivery across core backbone, SD‑WAN, security services, observability, and operations integration.

You are the single point of accountability for engineering decisions and design quality, partnering with the Program Director, Operations leadership (NOC/SOC), and agency stakeholders to ensure resilient, secure, and compliant outcomes.

• Define Service Requirements
  • Translate business, customer and technical requirements into clear network service specifications.
• Create End‑to‑End Service Designs
  • Develop high‑level and detailed designs that describe how the network service will work from end to end.
  • Document network capacity plans, routing, resilience and operational processes.
• Coordinate Across Technical Teams
  • Promote capabilities and offerings to internal groups, partners, and clients; present roadmaps, reference architectures and proof points.
  • Work with Engineering, Architecture, Network Operations (NOC), field engineers and vendors to ensure alignment.
• Ensure Operational Readiness
  • Define how the service will be supported (fault management monitoring, maintenance).
  • Prepare support documentation for operations teams and ensure handover to NOC/SOC.
• Manage Service Impact of Project Changes
  • Assess how design changes or network upgrades will affect existing services.
  • Ensure continuity, resilience and minimal customer interruption.
• Cross‑Functional Leadership & Collaboration
  • Facilitate collaboration among sales, pre‑sales, delivery, operations, and security teams to ensure seamless design‑to‑run transitions.
  • Blend technology and business strategy to develop compelling, outcome‑based solutions and articulate value in executive terms.
• Risk and Issues Management
  • Identify risks to service design, delivery or stability.
  • Develop migration plans (e.g., backup routes, redundancy, scheduling windows).
• Talent Development
  • Coach and mentor solution architects and sales teams; develop technical career paths, training plans and communities of practice.
• Core Technology Scope
  • Backbone & Routing: MPLS L3
    
    VPN, VRF/VRF‑lite, BGP, OSPF/IS‑IS, QoS/CoS, multicast, IPv6 and dual‑stack integration.
  • SD‑WAN:
    Policy‑based path selection, DIA/MPLS/broadband underlay diversity, controller design, segmentation, ZTP at scale, and app telemetry.
  • Security: NGFW (FTD/FMC, Palo Alto, Fortinet), IPS, DDoS mitigation, site VPN, AAA, segmentation, NAC integration, secure management VRFs.
  • Internet & Cloud Gateways:
    Redundant Internet egress, IX peering where applicable, cloud interconnects (Azure/AWS/GCP), NAT, DNS/DHCP/IPAM (Infoblox or equivalents).
  • Observability:
    Catalyst Center use‑cases, Thousand Eyes probes, Net Flow/IPFIX, syslog, SNMPv3, telemetry/streaming, Grafana dashboards, SLO/SLA instrumentation.
  • Operations & Automation:
    Event correlation tooling, configuration automation (Ansible, Python), standardized templates, compliance checks, and CI/CD for network changes.

• 10–15+ years in large‑scale network engineering/architecture, with 7+ years leading multi‑agency or enterprise programs.
• Minimum eight (8) years’ experience leading/supervising an engineering team responsible for services similar in size and scope in IT infrastructure management.
• Bachelor’s Degree from an accredited college or university in Engineering, Computer Science, Information Systems, Business, or other related discipline.
• A Master’s degree or higher and project management certification is preferred.
• Hybrid/onsite…
