About the role

Original posting from Nebius

About Nebius:

Nebius is leading a new era in cloud infrastructure for the global AI economy. We are building a full-stack AI cloud platform that supports developers and enterprises from data and model training through to production deployment, without the cost and complexity of building large in-house AI/ML infrastructure.

Built by engineers, for engineers. From large-scale GPU orchestration to inference optimization, we own the hard problems across compute, storage, networking and applied AI.

Listed on Nasdaq (NBIS) and headquartered in Amsterdam, we have a global footprint with R&D hubs across Europe, the UK, North America and Israel. Our team of 1,500+ includes hundreds of engineers with deep expertise across hardware, software and AI R&D.

The role 

 

We're looking for a senior support engineer who can handle difficult technical issues in modern cloud environments. This is not a traditional support role. The work is hands-on and technical: debugging Linux and Kubernetes issues, investigating problems in cloud infrastructure, and helping customers running AI workloads, distributed systems, and GPU-based environments. You'll work closely with engineering on production issues, help improve internal tools and troubleshooting workflows, and act as an escalation point when problems are unclear or high impact.

The role includes weekend rotation and incident response.

What you'll do

  • Investigate and resolve complex technical issues in customer environments
  • Troubleshoot across Linux, Kubernetes, cloud infrastructure, networking, storage, and GPU-related workloads
  • Support customers running containerized systems, inference workloads, training jobs, or other distributed platforms
  • Act as a senior escalation point for production incidents
  • Reproduce issues, narrow down root causes, and work with engineering on long-term fixes
  • Build or improve internal scripts, troubleshooting tools, and operational documentation
  • Help make support more scalable through better automation, observability, and process improvements
  • Communicate clearly with customers during active investigations and incidents
  • Take part in weekend coverage and urgent issue response

What we're looking for

  • Strong Linux troubleshooting skills
  • Strong Kubernetes and container experience
  • Solid understanding of cloud infrastructure in AWS, GCP, Azure, OpenStack, or similar environments
  • Good networking fundamentals
  • Ability to write scripts or small tools in Python, Bash, Go, or similar
  • Experience working on production issues that require structured debugging and cross-team collaboration
  • Ability to work independently and stay effective when the path to resolution is not obvious
  • Clear written communication, especially when explaining technical issues to customers and internal teams

Especially valuable

  • Experience with GPU-based infrastructure
  • Familiarity with AI/ML or LLM-related workloads
  • Understanding of inference and training pipelines
  • Experience improving observability, tooling, or operational workflows
  • History of building useful internal tools or automating repetitive work
  • Personal or open-source projects that show real technical depth

A strong candidate for this role usually

  • enjoys debugging messy infrastructure problems
  • takes ownership without waiting to be told exactly what to do
  • thinks beyond the immediate ticket
  • works well with engineering
  • looks for ways to reduce repeated operational pain, not just close cases
