Launched in November 2023, the Nebius platform provides high-end infrastructure and tools for training, fine-tuning and inference. Based in Europe with a global footprint we aspire to become the leading AI cloud for AI practitioners around the world.
Nebius is built around the talents of around 400 highly skilled engineers with a proven track record in developing sophisticated cloud and ML solutions and designing cutting-edge hardware. This allows all the layers of the Nebius cloud – from hardware to UI – to be built in-house, differentiating Nebius from the majority of specialized clouds. As a result, Nebius customers get a true hyperscaler-cloud experience tailored for AI practitioners.
As an NVIDIA preferred cloud service provider, Nebius offers the latest NVIDIA GPUs including H100, L40S, with H200 and Blackwell chips coming soon.
Nebius owns a data center in Finland, built from the ground up by the company’s R&D team. We are expanding our infrastructure and plan to add new colocation data centers in Europe and North America already this year, and to build several greenfield DCs in the near future.
Our Finnish data center is home to ISEG, the most powerful commercially available supercomputer in Europe and the 19th most powerful globally (Top 500 list, June 2024). It also epitomizes our commitment to sustainability, with energy efficiency levels significantly above the global average and an innovative system that recovers waste heat to warm 2,000 residential buildings in the nearby town of Mäntsälä.
Nebius is headquartered in Amsterdam, Netherlands, with R&D and commercial hubs across North America, Europe and Israel.
The role
We are looking for an expert-level Network Engineer (Network Architect) to join our team to ensure the development of our own data center infrastructure and the backbone network, research and develop the future of network interconnect for high-scale datacenter fabric with GPU interconnect, high-speed storage, in-depth investigations of emerging issues on the network together with neighboring server infrastructure, and cloud overlay teams.
You’re welcome to work in our office in Amsterdam.
In this position, your responsibility will be to:
- Provide technical design, operations, and assistance to related cross-functional team projects, including internal R&D and hardware as a service team.
- Design, evaluate, and provide solutions for all-around network services in cloud overlay and underlay environments.
- Research and evaluate R&D network equipment in the internal lab with the server team and network development team; prepare MVP of network segments for deploying new services.
- Design and develop data center networks with thousands of server ports, InfiniBand-based or other kinds of interconnect for GPU clusters, and automation and management tools.
- Provide documentation for end-to-end traffic flow, including intermediate devices like host-based FW/overlay data plane/cloud gateway, transit firewall, multi-vendor datacenter fabric and datacenter edge, and backbone part.
- Develop tools for in-depth investigation, monitoring, and healing of scalable datacenter networks, including data and control planes across vm/cloud overlay and underlay.
- Contribute to the launch of new regions within our cloud and GPU platforms.
We expect you to have:
- Expert and above-average understanding and experience in MPLS with different vendors, routing and switching for DataCenter, routing stack including proprietary vendors and opensource suites FRR/BIRD/goBGP, SR MPLS+SRv6, traffic balancing/ECMP, internet traffic engineering, and cloud overlay network technologies.
- Experience in researching, preparing, and documenting the developed network design and solution.
- Experience in developing plans and testing network infrastructure and vendors for specific purposes, workloads, and runtime.
- Experience in diagnosing problems with the TCP/IPv4/v6/multilayer encapsulation protocol stack in a CLOS topology data center network end-to-end, including intermediate equipment (FW, LB/uplinks and backbone).
- Knowledge of the design and internal architecture of modern network equipment, including ASIC, Whitebox, QoS mechanisms, and the operation of combination functionality.
- Experience with multivendor environments with backbox and white box switches, open-source NOS.
- Working proficiency in English.
It would be an added bonus if you had:
- Working knowledge of the GPU Interconnect cluster with more than 2k GPU cards.
- Practical experience with using SDK to Broadcom/spectrum ASICs.
