Job description

Job Summary:
Fluidstack is focused on delivering cutting-edge compute infrastructure for AI, aiming to enhance human freedom through technology. They are seeking a Network Engineer, Design & Engineering to take ownership of network design for AI training and inference workloads, collaborating with cross-functional teams to create deployable and optimized network architectures.
Responsibilities:
• Own the design lifecycle from customer requirements through deployable architecture.
• Produce topology designs, IP/addressing schemes, routing policy, and fabric configuration specifications for AI training and inference fabrics.
• Design front-end (out-of-band management, customer access), back-end (GPU-to-GPU training fabric), and storage network architectures.
• Design network architectures that adapt to different GPU platforms (NVIDIA, AMD, custom accelerators), server form factors, and workload profiles.
• Translate logical network designs into physical reality.
• Work cross functionally on rack elevation planning, power distribution constraints, structured cabling architecture, and cooling/airflow considerations.
• Produce comprehensive design packages that enable deployment teams to execute independently.
• Design lossless Ethernet fabrics optimized for RDMA (RoCEv2) workloads including PFC configuration, ECN tuning, traffic class design, and congestion management.
• Partner with Hardware Engineering on server/GPU platform integration, DC Operations on facility constraints and power planning, ICT on structured cabling feasibility, Software Engineering on automation requirements, and Validation teams on test plans and acceptance criteria.
• Participate in and lead design review sessions.
• Contribute to the development of reference architectures, design standards, and reusable design patterns that accelerate future deployments.
Qualifications:
Required:
• 5+ years of network engineering experience with a demonstrated focus on network design and architecture rather than purely operational roles.
• Experience designing datacenter network fabrics from requirements through deployment.
• Strong command of datacenter network fundamentals including CLOS/fat-tree topologies, BGP (eBGP underlay, iBGP/eBGP overlay), EVPN/VXLAN, IP addressing and subnetting at scale, and physical layer design.
• Working knowledge of RDMA network design (InfiniBand and/or RoCEv2), lossless Ethernet configuration (PFC, ECN, DCQCN), and the network performance requirements of distributed AI training workloads.
• Experience designing networks around specific GPU platforms (NVIDIA DGX/HGX, AMD MI-series, custom accelerator platforms).
• Ability to reason about network design in the context of physical constraints.
• Break complex design problems into fundamental components and reason through them systematically.
• Produce design documentation that is clear, complete, and actionable.
• Excellent at working across engineering disciplines and communicating design intent clearly to non-network stakeholders.
Preferred:
• Experience designing networks at hyperscale companies (Meta, Google, Microsoft, AWS) or large AI infrastructure providers.
• Deep familiarity with multiple network hardware platforms (Arista, Juniper, NVIDIA/Mellanox, Broadcom-based).
• Experience designing networks with automation in mind — consistent naming conventions, structured data models, templatable configurations.
• Experience with WAN topology design, DCI (Data Center Interconnect), optical transport, and backbone network architecture.
• Experience building something from scratch in a high-growth infrastructure or cloud company.
Company:
Fluidstack accelerates the world’s most ambitious AI projects by removing the bottlenecks to compute. Founded in 2017, the company is headquartered in London, GBR, with a team of 51-200 employees. The company is currently Growth Stage.
