[Remote] Network Engineer

Note: The job is a remote job and is open to candidates in USA. RZR is an AI-native advertising platform operating across machine learning, programmatic media, and mobile growth. The Network Engineer will design, implement, and manage high-performance network infrastructure for the company’s programmatic Demand-Side Platform, while optimizing low-latency data center networking, security, and automation. The role collaborates with infrastructure and backend engineering teams to build a scalable, highly automated network environment.

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

Skills

• 3+ years of professional network engineering experience (6+ years for Senior-level consideration)
• Deep familiarity with Mellanox Spectrum switches and ConnectX adapters
• 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

Benefits

• Own the core US data center network infrastructure — this is a high-ownership, high-visibility role, not a support function.
• Work daily with best-in-class open networking hardware and software: Mellanox Spectrum, Cumulus Linux, and Netris in a live production environment.
• Directly shape the backbone of a programmatic platform processing billions of real-time bid requests, where your engineering decisions have immediate, measurable impact.
• Join a small, senior infrastructure team where ideas get implemented — not committee'd to death.
• Be part of a company scaling aggressively, with the scope and trajectory to grow into a broader infrastructure leadership role.
