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
