About the Company

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.

About the Role

We are looking for a Senior Systems HPC Engineer to play a key role in building our hyperscaler platform, working across its core components while analyzing and optimizing the performance of large-scale GPU clusters at the intersection of hardware and software. You will operate across the full stack-from hardware and system software to networking (InfiniBand/RoCE), virtualization (KVM/QEMU), and distributed communication layers (e.g., MPI, NCCL).

Responsibilities

  • ● Focus on understanding system behavior across multiple layers, identifying performance bottlenecks, and driving improvements that shape how our clusters are built, operated, tuned, and validated.
  • ● Investigate and troubleshoot performance issues of GPU cluster under real workloads (training and inference)
  • ● Evaluate and integrate new hardware, system configurations and tuning approaches through software stack
  • ● Support complex performance-related escalations from internal teams and customers
  • ● Work closely with infrastructure, software engineering and hardware vendor teams (e.g. NVIDIA, Mellanox, Intel)
  • ● Contribute to hardware and cluster qualification (acceptance), ensuring systems meet performance expectations

Requirements

  • ● 5+ years of professional experience in system-level software development (focused on performance optimization, low-level programming).
  • ● 3+ years of hands-on experience with Linux systems (administration, troubleshooting, and performance tuning).
  • ● In-depth understanding of server architecture, including PCIe devices, NICs, Linux OS/Kernel, and high-performance computing (HPC) systems.
  • ● Strong proficiency in one or more performance-oriented programming languages (C/C++, Go, Python).

Benefits

  • ● Competitive compensation
  • ● Career growth and learning opportunities
  • ● Flexibility and ownership
  • ● Collaborative and innovative culture
  • ● Opportunity to work on impactful AI projects
  • ● International environment and talented teams
