Job description

The Cloud Network Engineer designs and operates the cloud network foundation as the company migrates to the cloud, exits data center capacity, and rebuilds its disaster recovery posture. This role owns cloud network architecture, the transit layer, hybrid connectivity such as Direct Connect and VPN, cloud DNS, segmentation, firewalls, and the multi-region network model that DR depends on. The engineer plans and executes network cutovers across migration waves, delivers configuration through Terraform, and manages colocation and carrier connectivity including circuit diversity. This is a hands-on role spanning both legacy enterprise networking and modern cloud network architecture, and serves as escalation for network incidents.

• Design and operate VPC architecture, address space allocation, and routing across a multi-account AWS environment.
• Build and run the transit layer using Transit Gateway or Cloud WAN.

• Experience supporting production cutovers under change control.
• Troubleshooting across TCP/IP, DNS, load balancers, and routing.
• Colocation and carrier circuit experience: cross connects, diverse path design, provider management.

Required Work Experience:

• 8+ years related work experience in networking
• 4+ years managing hybrid cloud/on-premises network infrastructure

Required Education:

• Related Bachelor's degree required or additional related work experience

Preferred Experience:

• Healthcare payer experience, including partner and EDI connectivity.
• AWS GovCloud networking, including cross-partition routing and DNS.
• Networking across two or more major cloud platforms, including connectivity between them. Which platform was primary does not matter.
• Terraform or equivalent infrastructure as code.
• Data center migration, exit, or secondary site standup experience.
