Senior Network Security Engineer

Jobtailor; California (MO); On-site; USD 140,000 - 190,000; Full time

Job summary

Jobtailor is seeking a senior Network Security Engineer to own ZTNA and microsegmentation across hybrid environments. You will design least-privilege policies, drive enterprise adoption, and collaborate with infrastructure, applications, and DevOps teams.

The role involves building segmentation maps, handling policy enforcement issues, and designing AI-assisted runbooks to automate security operations with governance frameworks established by the CISO organization.

Qualifications

• 7+ years of progressive experience in network security engineering, including firewall management and VPN/ZTNA.
• Experience with micro segmentation platforms and ZTNA.
• Strong knowledge of TCP/IP, DNS, routing/switching, proxy architectures, and cloud networking.
• Familiarity or willingness to learn AI/ML concepts, prompt engineering, and agentic automation.

Responsibilities

• Own day-to-day engineering, configuration, and optimization of ZTNA and microsegmentation across environments.
• Design and implement microsegmentation policies that enforce least-privilege network access across data center, cloud, and hybrid workloads.
• Drive enterprise-wide ZTNA adoption, partnering with infrastructure, application, and DevOps teams to onboard users and services.
• Build and maintain segmentation maps, traffic flow baselines, and policy rule sets aligned to business-critical applications and regulatory boundaries.
• Support and troubleshoot network access issues related to ZTNA policy enforcement, split tunneling, and identity-aware access controls.
• Learn to design, build, and manage AI agents (using platforms such as Kindo.ai, n8n, and Claude/Anthropic APIs) that automate routine network security operations including policy reviews, firewall rule audits, segmentation gap analysis, and anomaly triage.
• Build AI-assisted runbooks that enable autonomous or semi-autonomous handling of common network security events, escalating only when human judgment is required.
• Instrument and monitor AI agent performance, accuracy, and safety using human feedback loops and governance frameworks established by the CISO organization.
