Senior Network Security Architect - CA, Santa Clara, United States

Originally posted 9 September 2026 by the employer.

This role focuses on network security architecture including agentic AI workload isolation and DPU-based zero-trust micro-segmentation.

About the role

This role involves comprehensive network security architecture, focusing on design, identity-driven access control, security product enablement at scale, and emerging problem spaces such as agentic AI workload isolation. You will work on driving adoption of security solutions across NVIDIA's enterprise network.

What you'll do

• Build and implement network protection frameworks, including firewalls, intrusion detection/prevention systems, and VPNs.
• Partner with Enterprise Security on IAM, network access control (NAC/802.1X), and Zero Trust identity/posture-based policy.
• Enable NVIDIA's security products and tooling for internal customers at scale, driving them into org-wide production use.
• Design network-level isolation for autonomous/agentic AI workloads and multi-tenant environments.
• Lead efforts to move internal office and lab networks toward explicit east-west segmentation and dynamic Zero Trust controls.
• Research, evaluate, and recommend security solutions, products, and technologies.
• Conduct security audits and penetration tests to assess network security and identify vulnerabilities.
• Create and maintain documentation, including security policies, procedures, and network diagrams.
• Deliver guidelines, validated design standards, and direction on security standards/policies/roadmaps like Zero Trust.

What you'll need

• MS or PhD in Electrical Engineering, Computer Science, Computer Engineering, Artificial Intelligence, Data Science, Mathematics, Statistics, or equivalent experience.
• 12+ years of experience in building, managing and supporting large scale hybrid networks on the foundations of security.
• Experience developing automation technology with Python, Ruby, Go or other languages used in infrastructure automation.
• Advanced knowledge of NIST CSF, CIS controls, or MITRE ATT&CK frameworks.
• Strong knowledge of networking protocols and encryption services.
• Experience evaluating and testing new vendor platforms and in-house network initiatives for security issues.
• Knowledge of cloud platforms like AWS, Azure, or Google Cloud, and their respective security practices and services.
• Experience working cross-functionally with identity/IAM and product security teams.
• Comfort operating in ambiguity on emerging problem spaces, including securing AI agent platforms.
