Senior Infrastructure/​Systems Engineer - Remote Opportunity

About the Role

Plus8soft is seeking a Senior Infrastructure/Systems Engineer to join our team in a fully remote capacity. As a Senior Infrastructure/Systems Engineer, you'll manage and optimize core infrastructure for NoIP, ensuring high performance and reliability in a mission-critical environment. This is not a standard DevOps or Cloud-Native role; we require an individual who operates at the intersection of hardware and software.

What You'll Do

• 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: 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.
• English Proficiency: Good level of spoken and written English; must be able to explain complex technical stacks in depth during a strict screening process.

What We Offer

• Fully Remote: Preference for candidates in USA, LATAM, or Canada (Toronto/GMT-4 alignment).
• No Budget Restrictions: Compensation is commensurate with elite-level expertise and paid in USD.
• Direct Impact: Collaborate directly with founders in a fast decision-making environment.
• High Ownership: This mission-critical role allows you to have a real impact on the stability of global DNS/Infrastructure services.
• Elite Professional Growth: Work within an intensive environment where every word on your CV is respected and technical depth is the highest priority.
