Infrastructure Engineer

Plus8soft is a global engineering company providing outstaffing and outsourcing services for fast-growing startups and established international companies. We focus on delivering high-quality engineering talent across Web, Mobile, Cloud, AI/ML, and DevOps, with a strong presence in the US and global markets.

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; the candidate will operate at the intersection of hardware and software, handling bare‑metal performance, data center virtualization, and low‑level system debugging in a high‑load, mission‑critical environment.

• 
  
• 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.
  

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

• 
  
• Fully remote: preference for candidates in USA, LATAM, or Canada (Toronto/GMT‑4 alignment). Europe‑based candidates with significant overlap are welcome.
  
• No budget restrictions: compensation is commensurate with elite‑level expertise and paid in USD.
  
• Direct impact: direct collaboration with founders and a fast decision‑making environment.
  
• High ownership: this is a mission‑critical role where you will have a real impact on the stability of global DNS/infrastructure services. xcfaprz
  
• Elite professional growth: work within an intensive environment where every word on your CV is respected and technical depth is the highest priority.
