NCyber is seeking a Platform Infrastructure Engineer to design, build, automate, and maintain the infrastructure that powers mission-critical software systems supporting the National Security Community. This role owns the engineering of our compute, virtualization, container, and automation platforms. You'll work closely with software engineers, network engineers, security engineers, and technical leadership to deliver reliable, scalable infrastructure while helping modernize our architecture toward cloud-native and hybrid-cloud environments. This position is ideal for someone who enjoys building platforms rather than simply maintaining servers.

You'll help design, deploy, and operate the infrastructure that supports production software systems from development through deployment.

Responsibilities include:

• Design and maintain Linux-based infrastructure platforms
• Engineer and operate private cloud environments built on OpenStack
• Build repeatable infrastructure using Infrastructure-as-Code and configuration management
• Design and maintain containerized application platforms using Docker
• Automate infrastructure deployment, configuration, and lifecycle management
• Support cloud migration initiatives across AWS and Google Cloud
• Build CI/CD and GitOps workflows that improve deployment consistency
• Engineer observability solutions including centralized logging and monitoring
• Support Apache NiFi dataflow infrastructure
• Troubleshoot complex infrastructure, virtualization, networking, and storage issues
• Improve platform reliability, scalability, and security
• Produce architecture documentation and operational runbooks
• Mentor junior engineers and participate in technical design reviews

• The ability to obtain and maintain a security clearance
• 5+ years designing or operating Linux infrastructure
• Strong Linux administration experience (Ubuntu/Debian preferred)
• Experience operating virtualized or private cloud environments
• Experience with Docker and containerized workloads
• Experience with Ansible or similar configuration management tools
• Experience automating infrastructure deployments
• Experience troubleshooting production infrastructure
• Strong scripting skills (Python, Bash, or similar)

Experience with several of the following:

• Virtualization / Hypervisor Solutions (OpenStack, Vmware, Proxmox, etc.)
• Apache NiFi
• Elasticsearch / Kibana
• GitOps workflows
• Terraform or OpenTofu
• AWS or Google Cloud
• Observability and monitoring platforms (e.g., Prometheus, Grafana, Loki, Splunk)
• PostgreSQL
• Containerization and orchestration platforms (Docker, Kubernetes, ECS, etc.)
• AI infrastructure (vLLM, Open WebUI, Jupyter)
