Rampant Technologies is an independently owned defense contractor delivering specialized support to the most sensitive national security missions across the Department of Defense and the Intelligence Community. Guided by our philosophy of Securing, Enabling, and Executing our customers' critical missions, we bring together elite, cleared teams to solve the hardest technical challenges in intelligence analysis, signals processing, full-spectrum cyber operations, AI/ML and analytics, software engineering, and enterprise IT.

We hire mission and technical specialists, prioritizing people over processes and quality over quantity, so that every engagement advances the mission and shapes the future of national security.

The Cloud Infrastructure Engineer is responsible for designing, building, and maintaining scalable cloud and on-premises infrastructure that supports mission-critical applications and services. This includes administering and hardening Linux systems, architecting networking, storage, and compute resources, and building infrastructure as code to ensure environments are repeatable and version-controlled. A core focus of the role is installing, configuring, and maintaining Kubernetes clusters and the foundational CNCF tooling that runs on top of them, including monitoring, ingress, service mesh, and certificate management.

Beyond day-to-day infrastructure operations, this role partners closely with development and platform teams to translate application requirements into reliable, secure infrastructure solutions. Responsibilities include implementing and maintaining CI/CD pipelines, enforcing security best practices such as identity and access management and secrets management, and participating in on-call rotations to maintain system reliability and uptime. The Cloud Infrastructure Engineer also documents infrastructure architecture and operational procedures, evaluates new tools and practices to improve efficiency and maturity, and contributes to the team's overall technical direction.
