Description
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.
Your responsibilities will include:
- Designing and evolving scalable data center network architectures (CLOS/leaf-spine) for high-throughput, low-latency environments
- Owning end-to-end deployment and lifecycle management of routing and switching infrastructure across production environments
- Developing and maintaining network design documentation, standards, and operational procedures
- Planning, executing, and validating network infrastructure testing, including vendor evaluation and benchmarking
- Diagnosing and resolving complex network issues across the TCP/IPv4/v6 stack in large-scale distributed environments
- Optimizing traffic engineering, ECMP, and load balancing strategies to ensure efficient utilization of network resources
- Implementing and operating MPLS-based technologies, including L3 VPNs and segment routing (SR-MPLS, SRv6)
- Collaborating with hardware, systems, and software teams to integrate networking with compute and storage infrastructure
- Automating network operations and workflows to improve reliability, scalability, and operational efficiency
- Ensuring high availability and performance of production networks through proactive monitoring and continuous improvement
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
