Summary

We are seeking a Senior Staff Engineer to lead the design and development of next-generation AI infrastructure platforms focused on GPU-based data centers, networking, and orchestration systems.

This is a high-impact, hands-on technical leadership role where you will architect and build systems that enable deployment, monitoring, and optimization of large-scale infrastructure supporting AI workloads across modern data center environments.

You will operate at the intersection of:

• Data center networking (L2/L3, AI fabrics)
• Infrastructure management, monitoring, and diagnostics

This role requires deep technical expertise along with the ability to drive end-to-end solutions from architecture through deployment and troubleshooting.

Detailed Description

• Lead the architecture, design, and development of scalable AI infrastructure platforms supporting GPU-based data center environments
• Build and enhance orchestration systems responsible for infrastructure deployment, provisioning, monitoring, and lifecycle management
• Design distributed systems with a focus on scalability, resiliency, fault tolerance, concurrency, and performance optimization
• Develop infrastructure observability and diagnostics capabilities across GPU, networking, and storage environments
• Define telemetry, health monitoring, and performance validation strategies for large-scale AI infrastructure deployments
• Develop and support data center networking and orchestration workflows including ZTP, DHCP, provisioning, and automated infrastructure configuration
• Work across modern AI fabric and data center networking architectures including Clos fabrics, EVPN, and L2/L3 networking environments
• Write high-performance backend software and infrastructure services using Python or Go within Kubernetes-based environments
• Troubleshoot and resolve complex infrastructure, networking, orchestration, and performance issues in live production data center environments
• Lead root cause analysis efforts and drive issues through resolution across software, networking, and infrastructure layers
• Partner cross-functionally with engineering, hardware, platform, lab, and customer teams to support deployments and operational success
• Drive technical direction, architecture decisions, engineering best practices, and mentorship across the organization
• Translate real-world deployment challenges into scalable engineering solutions that improve reliability, automation, and operational efficiency
• Operate as a hands-on technical leader capable of driving initiatives from architecture and development through deployment and production support
