Job description

We are seeking a highly skilled Network Engineer to join our Networks team supporting the U.S. Africa Command (AFRICOM) mission in Stuttgart, Germany. The ideal candidate is an innovative professional who can deliver a rich feature set, high availability, and exceptional performance of automation and orchestration tools while maintaining a secure, mission-ready network infrastructure.

Manage and troubleshoot datacenter network fabrics using Cisco ACI (Application Centric Infrastructure) and Cisco Nexus switching platforms. Deploy, manage, and update Palo Alto and Cisco Firepower firewalls, including centralized management platforms (Panorama, FMC). Administer Cisco Identity Services Engine (ISE) for secure endpoint access, policy enforcement, and Zero Trust architecture support. GEM One Enterprise Management: Architect, deploy, and maintain the General Dynamics GEM One management infrastructure to centrally monitor and administer a global fleet of High Assurance Internet Protocol Encryptor (HAIPE) devices. Cryptographic Operations: Perform expert-level remote device provisioning, configuration, and secure key management for Type 1 encryptors (e.g., TACLANE-Micro, TACLANE-FAS) via GEM One. Develop automation frameworks and leverage network automation tools (Ansible, Python, REST APIs) to streamline deployments and support Software-Defined Access (SDA). Maintain core network services including F5 load balancers and Infoblox for DNS, DHCP, and IPAM. Proactively identify and resolve performance bottlenecks and single points of failure. Create a roadmap for maturing DevOps practices and drive adoption of Infrastructure as Code (Terraform). Gather and analyze metrics for performance tuning, fault discovery, and after-action reporting. Work with operations teams to build automation use‑cases and improve reliability through rigorous testing and release procedures.
