Act as the technical authority for SONiC deployments running on Cisco Silicon One platforms in large-scale production environments.
Provide architectural guidance and operational support for hyperscale data center fabrics supporting AI/ML workloads.
Troubleshoot complex issues across the stack including SONiC containers, Linux networking, routing protocols, and ASIC forwarding behavior.
Perform deep debugging and analysis using Silicon One SDK tools and ASIC telemetry to identify hardware and software interactions.
Support both production and pre-production validation environments running SONiC and Cisco platforms including NCS5500, Catalyst 8000, Nexus 3000/9000, and NCS1K.
Collaborate directly with Cisco silicon architects, SONiC development teams, and software engineering groups to resolve defects and improve platform capabilities.
Optimize network fabrics designed for AI/ML clusters using RDMA over Converged Ethernet (RoCE) and other high-performance transport mechanisms.
Guide the customer in adopting DevOps-driven operational models, including CI/CD pipelines for SONiC software validation and infrastructure automation.
Help implement observability, telemetry, and automated validation frameworks to improve reliability at hyperscale.
Act as a trusted technical advisor, building strong relationships with customer network engineering and infrastructure teams.
