Quest Oracle Community; Bedford, Northern (MA, KY); Hybrid; USD 131,000 - 237,000; Full time

Job summary

Leidos is seeking a Cloud Network Architect to lead secure multi-cloud networking across AWS, Azure, GCP, and OCI for the Air Force Cloud One Next program. You will define standards, automate provisioning with IaC, and work with cybersecurity, DevSecOps, and operations to meet DoD requirements.

You will design scalable, highly available networks, implement Zero Trust, and ensure compliance across CSPs with reference architectures and governance.

Qualifications

• Bachelor's degree in Computer Science, Information Technology, Network Engineering, Systems Engineering, or a related technical discipline and 12-15 years of prior relevant experience, or equivalent additional experience in lieu of degree.
• Extensive experience designing and operating enterprise-scale network architectures, including routing, switching, firewalls, DNS, load balancing, VPNs, private connectivity, and network segmentation.
• Demonstrated experience designing cloud network architectures in multiple CSPs, with strong knowledge of at least two of the following: AWS, Azure, GCP, or OCI, and the ability to architect common solutions across heterogeneous cloud environments.
• Advanced knowledge of cloud networking concepts including VPC/VNet architectures, transit networking, peering, private endpoints, cloud-native firewalls, NAT, load balancing, DNS, and private connectivity services.
• Advanced knowledge of TCP/IP and enterprise routing technologies, including BGP, route propagation, route filtering, CIDR planning, and IP address management.
• Strong understanding of network security architecture, Zero Trust principles, network segmentation, firewalls, security groups, access control policies, encryption, and traffic inspection.
• Experience designing secure hybrid cloud connectivity using technologies such as AWS Direct Connect, Azure ExpressRoute, Google Cloud Interconnect, OCI FastConnect, and IPsec VPNs.
• Experience implementing network infrastructure through Infrastructure as Code, preferably using Terraform, Ansible, GitLab CI/CD, and Git-based configuration management practices.
• Experience designing resilient network architectures across multiple availability zones, regions, and connectivity paths with clearly defined failure and recovery strategies.
• Experience designing or operating network architectures within DoD, federal, or other highly regulated environments, including familiarity with RMF, STIGs, NIST security controls, and secure enclave architectures.
• Ability to translate complex network architectures and technical tradeoffs into clear recommendations for engineering teams, cybersecurity stakeholders, program leadership, and Government customers.
• DoD Secret security clearance required.

Responsibilities

• 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 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 IaC technologies such as Terraform and Ansible, integrating network configuration into GitLab-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 requirements, operational constraints, and enterprise architecture objectives.
• Technical Leadership: Serve as a senior technical advisor to cloud, network, cybersecurity, DevSecOps, and operations teams, providing design guidance and resolving complex networking and connectivity challenges.
• Technology Evaluation: Evaluate cloud-native and third-party networking technologies to identify opportunities to improve scalability, security, automation, observability, and operational efficiency.
• Documentation & Knowledge Transfer: Develop architecture diagrams, interface definitions, network patterns, technical decision records, and implementation guidance that enable engineering teams to consistently implement approved architectures.
