Senior Network Engineer

Role description

Role Overview

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.

What You Will Do

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, and diagnose and resolve complex network issues across the TCP/IPv4/v6 stack in large-scale distributed environments.

Why It Might Be a Fit

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. You will collaborate with hardware, systems, and software teams to integrate networking with compute and storage infrastructure and automate network operations and workflows to improve reliability, scalability, and operational efficiency.

Requirements

• 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

Benefits

• Comprehensive health insurance
• 401(k) plan with company contribution
• Paid time off and public holidays
• Flexible working hours
• Professional development and certification support
