Network Architect

Leidos delivers innovative solutions through a diverse, talented team dedicated to making the world safer, healthier, and more efficient through information technology, engineering, and science. Everything we do is built on a commitment to do the right thing for our customers, our people, and our community. We offer a robust benefits package including competitive salaries, a 401(k) retirement plan, comprehensive medical/dental/vision coverage, flexible work schedules for work/life balance, and tuition reimbursement.

Leidos is seeking a Cloud Network Architect to provide technical leadership for the design, integration, and evolution of secure multi-cloud networking capabilities supporting the U.S. Air Force Cloud One Next (C1N) ACSS contract. In this role, you will serve as a senior technical authority for network architecture across AWS, Microsoft Azure, Google Cloud Platform (GCP), and Oracle Cloud Infrastructure (OCI). You will develop common networking patterns while accounting for the unique capabilities and constraints of each Cloud Service Provider (CSP), enabling secure and resilient connectivity across Cloud One environments, Department of the Air Force (DAF) networks, mission systems, and external services.

The Cloud Network Architect will work closely with cloud engineering, cybersecurity, platform engineering, operations, and program leadership to translate mission and security requirements into scalable network architectures. The role will establish technical standards, reference architectures, and automation patterns that reduce CSP‑specific complexity while maintaining the security, availability, performance, and compliance requirements of DoD environments.

• Multi‑Cloud Network Architecture:
  Design and maintain enterprise network architectures across AWS, Azure, GCP, and OCI, including virtual networks, routing, segmentation, ingress/egress, private connectivity, DNS, load balancing, and network security services.
• Network Architecture Standards:
  Develop reusable reference architectures, design patterns, and technical standards that provide consistency across CSPs while appropriately leveraging cloud‑native networking capabilities.
• Hybrid & Cross‑Cloud Connectivity:
  Architect secure connectivity between cloud environments, DoD networks, mission partner environments, and external services using technologies such as VPNs, private circuits, cloud interconnects, and software‑defined networking.
• Routing & Segmentation:
  Define enterprise routing, IP address management (IPAM), network segmentation, traffic isolation, and trust‑boundary strategies supporting multiple environments, tenants, security domains, and DoD Impact Levels.
• Security Architecture:
  Partner with cybersecurity teams to implement Zero Trust networking principles, network access controls, firewall policies, encryption, traffic inspection, microsegmentation, and secure ingress/egress architectures.
• Resiliency & Availability:
  Design highly available and fault‑tolerant network architectures that account for CSP regions, availability zones, redundant connectivity, failure domains, disaster recovery, and continuity of operations.
• Infrastructure as Code:
  Define and implement automated network provisioning using Infrastructure as Code (IaC) technologies such as Terraform and Ansible, integrating network configuration into Git Lab‑based engineering and deployment workflows.
• Network Observability:
  Establish approaches for network monitoring, flow logging, telemetry, performance analysis, capacity management, and troubleshooting across heterogeneous cloud environments.
• Architecture Governance:
  Review proposed network changes and cloud architectures to ensure alignment with established standards, security…
