Infrastructure Engineer

Job Description

We are seeking a seasoned Senior Infrastructure / Systems Engineer to manage and optimize core infrastructure for NoIP. This is not a standard DevOps or Cloud-Native role; we require an individual who operates at the intersection of hardware and software. You will be responsible for bare-metal performance, data center virtualization, and low-level system debugging in a high-load, mission-critical environment.

Responsibilities

• Manage Core Infrastructure: Oversee and optimize bare-metal servers and physical data center deployments.
• Optimize Virtualization: Maintain and tune expert-level virtualization environments using KVM or Proxmox, focusing on I/O and CPU/RAM efficiency.
• Low-Level Debugging: Perform deep-system troubleshooting, kernel tuning, and performance profiling to ensure 24/7 stability.
• Network Engineering: Handle high-load networking troubleshooting, routing protocols, and packet-level analysis.
• Maintain Containers: Manage Docker and container runtimes with a focus on how they interact with Linux namespaces and cgroups.
• System Stewardship: Prioritize stability and resource efficiency over general automation, acting as a “builder” of the foundation.

Requirements

• Linux Internals Mastery: Deep, low-level command of Linux (kernel tuning, system calls, and internals).
• On-Prem Expertise: Extensive experience with bare-metal, physical hardware, and data center operations.
• Networking Deep-Dive: Beyond basic CIDR—strong command of routing, switching, and high-load network architectures.
• Virtualization Specialist: Proven experience with KVM, Proxmox, or similar “low-level” hypervisors.
• Container Knowledge: Solid understanding of Docker/process isolation (not just Kubernetes orchestration).
• High-Load Experience: Background in CDN, Hosting, or ISP infrastructure is a massive plus.
