CFD Research is seeking a highly skilled Cloud Network Engineer to design, implement, and operate secure, high‑performance networks that span on‑premise data centers, public cloud environments, and enclave‑based domains. The ideal candidate will have deep hands‑on experience with cloud networking, software‑defined networking (SDN), and container‑native networking solutions, particularly within Kubernetes environments. This Cloud Network Engineer will spend the majority of their working at the customer sites in Huntsville.

Key Responsibilities

Design & Deploy Secure Networks

Architect and configure restricted computer networks and secure inter‑domain routes.
Implement network segmentation, access controls, and policy enforcement across cloud and on‑premise resources.

Cloud & Multicast Networking

Build and manage cloud networking infrastructure (AWS, Azure, GCP, etc.).
Configure and troubleshoot multicast UDP and broadcast UDP traffic for high‑throughput applications.

Software‑Defined & Hardware‑Defined Solutions

Deploy and maintain Software Defined Network (SDN) platforms and hardware‑based network appliances.
Integrate network services with Kubernetes using CNI plugins and container‑based networking.

Hybrid Cloud Integration

Connect remote cloud instances to on‑premise data centers, ensuring reliable routing and latency optimization.
Support hybrid cloud architectures and remote enclave connectivity.

Automation & Monitoring

Automate network provisioning and changes using IaC tools (e.g., Terraform, Ansible).
Implement robust monitoring, logging, and alerting for network health and security events.

Collaboration & Documentation

Work closely with security, DevOps, and application teams to define network access protocols and rules.
Produce clear documentation, runbooks, and knowledge‑base articles for all network solutions.

Must‑Have Qualifications

Network Design Experience - Proven experience setting up restricted/compliant networks and securing inter domain/enclave communication.
Cloud Networking - Hands on experience with cloud networking services (VPC, VNets, peering, transit gateways).
Linux Operation Systems - Experience with Linux OS
Multicast/UDP - Practical knowledge of multicast UDP and broadcast UDP traffic handling.
SDN / Hardware Defined Networking - Experience with both software defined and hardware defined networking technologies.
Kubernetes Based Networking - Direct experience designing, deploying, and troubleshooting networking within Kubernetes clusters.
Secure Routing Across Domains - Ability to create and manage secure routing paths between isolated domains or enclaves.

Nice‑to‑Have Qualifications

CNI Expertise – Experience with one or more Container Network Interfaces (CNI): Cilium, Calico, Multus, or similar.
Enterprise Software Hosting – Background deploying and supporting enterprise‑grade applications in production environments.
Network Access Policy Development – Experience defining and governing network access protocols, firewall rules, and zero‑trust policies.
