Job Description:

Parsons is seeking a Senior Cloud Network Engineer to help modernize and scale the network architecture for a mission-critical global platform operating across remote sites, centralized hubs, and AWS cloud environments. This role is ideal for an engineer who understands both the realities of physical field networking and the design of cloud-native, software-defined network fabrics.

You will help transform a legacy, static, IP-heavy networking estate into a more virtualized, elastic, observable, and cloud-managed architecture. This includes hybrid connectivity from physical networks and appliances into AWS, building resilient virtual network topologies, and designing for highly variable traffic patterns ranging from steady-state operations to large event-driven surges.

We are especially interested in engineers who can combine deep networking fundamentals, AWS cloud networking, automation/IaC, and emerging AIOps/telemetry-driven operations to improve reliability, scalability, and operational insight.

What you will do

• Design and implement hybrid network architectures spanning field sites, centralized environments, and AWS

• Build and modernize VPC-based network fabrics using AWS services

• Integrate physical firewalls, routed networks, and VPN-connected sites with virtual cloud networking and security appliances

• Reduce dependence on static routing and static public IP-heavy designs by introducing more flexible, software-defined, policy-driven network patterns

• Design for burst traffic, event-driven surges, failover, and high availability

• Create repeatable network deployments using Terraform, automation, and infrastructure-as-code practices

• Improve network observability through flow logs, metrics, synthetic tests, alerting, and telemetry pipelines

• Contribute to AIOps/capacity planning initiatives using telemetry for anomaly detection, forecasting, and faster incident response

• Partner with cloud platform, field communications, software, observability, and security teams to deliver reliable end-to-end connectivity

Required qualifications

• 8+ years of experience in network engineering, cloud networking, or hybrid infrastructure engineering

• Strong hands-on experience with AWS networking in production, including VPC design, Transit Gateway, VPN/IPsec, Direct Connect, PrivateLink, Route 53, and security segmentation and routing design

• Strong networking fundamentals, including IP networking, routing, BGP, NAT, DNS, high availability/failover, and network security fundamentals

• Experience connecting physical networks into cloud-based virtual networks

• Experience with Terraform or similar infrastructure-as-code tooling

• Experience troubleshooting across network, platform, and application boundaries

• Support for high-availability, mission-critical, or globally distributed systems

Preferred qualifications

• Experience with virtual firewalls/appliances such as Cisco ASA/Firepower, Palo Alto, Fortinet, or equivalent

• Experience with network automation using Python, Ansible, or CI/CD workflows

• Experience with SD-WAN, network virtualization, or large-scale WAN modernization

• Experience with network observability tools and platforms such as Grafana, ELK, Kibana, flow log analysis, and synthetic monitoring

• Experience applying AIOps, analytics, or ML-assisted techniques to anomaly detection, capacity planning, traffic analysis, and incident reduction

• Experience with remote systems, low bandwidth, or unreliable connections

• AWS certifications or equivalent practical cloud networking depth

Why join Parsons in this role

• Drive transformation of legacy field networking to cloud-native hybrid networkin
