Senior Network Security Architect

Responsibilities

• Build and implement network protection frameworks, including firewalls, intrusion detection/prevention systems, VPNs and other security technologies.
• Partner with Enterprise Security — working across IAM, network access control (NAC/802.1X), and Zero Trust identity/posture-based policy so that network access decisions are increasingly driven by who/what is connecting and its security posture, not just IP/VLAN placement.
• Partner with Product Security (ProdSec) to enable NVIDIA's own security products and tooling for internal customers at scale — taking platforms validated in staging/pilot and driving them into org-wide production use (e.g., artifact/supply-chain scanning gates, access-control gateways, endpoint/network detection…
• Design network-level isolation for autonomous/agentic AI workloads ("autorun") and multi-tenant environments running disparate, co-located workloads at different trust levels — defining trust-domain boundaries, segmentation models, and long-term end-state architecture (e.g., firewall-based "chambers" today, migrating…
• Lead efforts to move NVIDIA's internal office and lab networks from a largely flat, implicitly-trusted model toward explicit east-west segmentation — internal/collapsed firewalls at key boundary points, a service-catalog-based access model, and a foundation for dynamic Zero Trust controls (posture, identity,…
• Research, evaluate, and recommend security solutions, products, and technologies that can enhance the network's security posture.
• Partner and conduct security audits and penetration tests to assess the network's security and identify vulnerabilities.
• Create and maintain documentation, including security policies, procedures, network diagrams, and multi-functional feasibility reviews that define clear ownership boundaries between network, identity, platform, and application-security teams.
• Deliver guidelines, validated design standards, and direction on security standards/policies/roadmaps like Zero Trust to ensure consistent security practices across the organization. Provide domain expertise, consultation, and critical issue support.
