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 are looking for a Senior Network Engineer to design, build, and operate large-scale, high-performance data center networks supporting GPU-dense AI workloads. You will take end-to-end ownership of service provider–grade and CLOS-based network infrastructure, ensuring reliability, scalability, and predictable performance across distributed environments. This role requires deep expertise in routing, switching, and modern data center fabrics, with a strong focus on production operations, root cause analysis, and continuous improvement of network systems.

Your responsibilities will include:

  • Design and evolve scalable data center network architectures (CLOS/leaf-spine) for high-throughput, low-latency environments

  • Own end-to-end deployment and lifecycle management of routing and switching infrastructure across production environments

  • Develop and maintain network design documentation, standards, and operational procedures

  • Plan, execute, and validate network infrastructure testing, including vendor evaluation and benchmarking

  • Diagnose and resolve complex network issues across the TCP/IPv4/v6 stack in large-scale distributed environments

  • Optimize traffic engineering, ECMP, and load balancing strategies to ensure efficient utilization of network resources

  • Implement and operate MPLS-based technologies, including L3 VPNs and segment routing (SR-MPLS, SRv6)

  • Collaborate with hardware, systems, and software teams to integrate networking with compute and storage infrastructure

  • Automate network operations and workflows to improve reliability, scalability, and operational efficiency

  • Ensure high availability and performance of production networks through proactive monitoring and continuous improvement

What we expect you to have:

  • Expert-level knowledge (CCIE/JNCIE or equivalent) in MPLS, routing, and switching for service provider and data center networks

  • Strong experience with Ethernet switching, VXLAN, and modern cloud overlay networking technologies

  • Deep expertise in routing protocols including BGP and IS-IS

  • Hands-on experience with segment routing (SR-MPLS, SRv6), L3 MPLS VPNs, and ECMP-based traffic balancing

  • Proven experience designing and documenting large-scale network architectures

  • Experience developing and executing network testing strategies and validating vendor solutions

  • Strong troubleshooting skills across the TCP/IPv4/v6 stack in CLOS-based data center environments

  • Solid understanding of network hardware architecture, QoS mechanisms, and packet processing pipelines

  • Hands-on experience with network equipment from vendors such as Juniper, Arista, Huawei, and Mellanox

  • Working proficiency in English

It will be an added bonus if you have:

  • Working proficiency in an additional European language

  • Experience with public cloud networking and GPU/InfiniBand environments

  • Knowledge of software-defined networking (SDN) overlays in cloud environments

  • Proficiency in Python, Go, or other programming languages in Linux environments

  • Experience using programming languages for network automation and tooling

Working conditions:

  • Remote work within the United States

  • Work closely with globally distributed infrastructure and engineering teams

  • Participation in on-call rotations to support production environments

Key employee benefits:

  • Comprehensive health insurance

  • 401(k) plan with company contribution

  • Paid time off and public holidays

  • Flexible working hours

  • Professional development and certification support

Compensation:

  • $125,000 – $180,000 USD per year, depending on experience and qualifications
