Senior Network Engineer (Amsterdam)

Together AI is looking for a Senior Network Engineer to design, deploy, and operate the global network infrastructure supporting our production services and high-performance AI compute environments.

This is a hands-on engineering role for someone with deep networking expertise who can also troubleshoot across Linux, Kubernetes, automation, and application boundaries. You will work on large-scale, multi-vendor data center networks and help ensure they remain highly available, reliable, scalable, and performant.

The ideal candidate has strong networking fundamentals, experience operating complex networks at scale, and a structured, evidence-based approach to troubleshooting. You should be comfortable owning problems from initial investigation through root cause and resolution, including situations where the issue may extend beyond the network itself.

• 8+ years of professional experience designing, building, and supporting large-scale production data center, cloud, service-provider, or high-performance computing networks (excluding enterprise networks).

• Deep understanding of TCP/IP and strong experience with technologies such as BGP, OSPF, VXLAN, EVPN, ECMP, and QoS.

• Experience designing and supporting multi-tenant network environments using technologies such as VRFs, VLANs, overlays, and policy-based segmentation.

• Hands-on experience deploying and troubleshooting network platforms from vendors such as Arista, Cisco, Juniper, and NVIDIA.

• Strong troubleshooting skills using tools such as Wireshark, tcpdump, MTR, curl, nmap, and standard Linux networking utilities.

• Ability to diagnose connectivity, latency, packet-loss, routing, and performance issues across the network, host, and application layers.

• Experience developing or maintaining network automation using Python, Ansible, or similar tools.

• Experience working through a Git-based software development lifecycle, including branching, code review, validation, linting, testing, CI/CD, deployment, and rollback.

• Working knowledge of Kubernetes networking, including pods, services, CNIs, and basic connectivity troubleshooting.

• Foundational knowledge of RDMA networking and technologies such as RoCE or InfiniBand.

• Experience with cloud networking in AWS, GCP, or Azure.

• Strong Linux administration and troubleshooting skills.

• Design, deploy, operate, and maintain global, multi-vendor, multi-protocol networks supporting high-performance AI compute infrastructure.

• Troubleshoot complex network and application-connectivity issues, identify root causes, and drive problems through resolution.

• Analyze telemetry, packet captures, logs, and performance data to identify network degradation, congestion, packet loss, and capacity constraints.

• Participate in architecture and design reviews to ensure solutions meet requirements for performance, availability, scalability, security, and operational supportability.

• Develop and maintain automation, validation, and operational tooling that improves network reliability and reduces manual effort.

• Evaluate network hardware, software, optics, and emerging technologies for use in production environments.

• Establish standards and operational best practices for network design, deployment, monitoring, change management, and incident response.

• Lead projects addressing complex technical challenges and contribute directly to the network engineering roadmap.

• Partner with infrastructure, systems, security, and application teams to troubleshoot issues that cross traditional ownership boundaries.

• Must have hands-on experience deploying or
