Leadership is given to those who show initiative and consistently deliver excellence. Work ethic and strong prioritization skills are important. All engineers are expected to have strong communication skills. They should be able to concisely and accurately share knowledge with their teammates.

About the Role

Grok and X are powered largely from our own on‑premise infrastructure which enables us to move at speed and efficiency when deploying vast amounts of capacity. People wouldn’t be able to enjoy participating in the townhall on X or use Grok to understand the universe if it weren’t for our Edge networking infrastructure.

We are seeking two senior engineers that help architect, develop, and build our peering and transit infrastructure with associated routing policies, eDNS, cloud connectivity, CGNAT, and load balancer fleets. The two successful candidates will have great Python skills to remove repetitive engineering cycles and auto‑mitigate customer impacts.

Responsibilities

• Architect, develop, and maintain peering and transit infrastructure, including routing policies, eDNS, cloud connectivity, CGNAT, and load balancer fleets.
• Leverage Python scripting to automate repetitive engineering tasks and proactively mitigate customer impacts.
• Manage and troubleshoot DNS infrastructure to ensure reliable performance.
• Oversee and resolve issues related to cloud VPCs and connected network hardware.
• Diagnose and resolve complex TCP/IP issues to maintain seamless network operations.
• Collaborate with cross‑functional teams to enhance infrastructure efficiency and support xAI’s AI platforms.

Required Qualifications

• 7+ years of experience with edge network hardware, including load balancers, CGNAT, routers, and switches.
• 7+ years of routing experience in backbones, peering, and transit areas with expertise in traffic engineering.
• 5+ years of experience using Python scripting to automate deployments and break/fix tasks.
• 3+ years of experience managing DNS infrastructure.
• 3+ years of experience managing and troubleshooting cloud VPCs and connected network hardware.
• Proven ability to troubleshoot complex TCP/IP issues.

Preferred Qualifications

• Experience with A10 Networks, NGINX, or open‑source load balancer/CGNAT software.
• Familiarity with Route53 and UltraDNS.
• Expertise in GCP, AWS, and OCI VPC architecture and troubleshooting.
• Knowledge of Kubernetes Ingress.
• Demonstrated success in on‑call rotations and incident response in high‑stakes environments.
• Strong problem‑solving skills and adaptability in a fast‑paced, ambiguous setting.
