You will work hands-on with modern open networking technologies — including Mellanox Spectrum hardware, Cumulus Linux, and Netris — to build and maintain a low-latency, highly automated data center fabric. You will collaborate closely with global infrastructure and backend engineering teams to deliver a network environment that scales with the business.

• Strong proficiency in Cumulus Linux (Debian-based) and general Linux system administration.
• Hands-on experience with Netris for VPC-style networking on-premises or in hybrid cloud environments.
• Expert-level knowledge of BGP, OSPF, EVPN-VXLAN, and LACP.
• Proficiency in Python or Go for network automation.
• Bachelor's or Master's degree in Computer Science, Engineering, or a related technical field.

Responsibilities

• Design, deploy, and maintain high-density data center networks utilizing Mellanox switches and adapters.
• Administer and optimize network nodes running Cumulus Linux, ensuring stable and high-performance routing and switching.
• Manage and orchestrate network operations using Netris for automated, controller-based networking.
• Monitor and tune network performance for real-time systems, with a focus on throughput and latency.
• Implement and manage firewall rules, VPNs, and access control lists (ACLs) to protect infrastructure and data assets.
• Develop automation workflows to eliminate manual configuration, improve consistency, and accelerate deployment cycles.
