• Own the architecture, implementation, and continuous improvement of Lumin’s network security program across cloud, SD-WAN, and ZTNA layers—designing identity-aware, policy-driven controls that secure both human and machine (agent) identities. • Design and deliver fully automated, end-to-end network security change management pipelines that eliminate manual toil, accelerate change velocity, and maintain audit-ready evidence at every step. • Build and operate real-time network telemetry, monitoring, and alerting systems that provide deep visibility into network activity — integrating threat intelligence feeds, cloud connectivity data, and asset inventories into a unified, automated network defense posture. • Engineer production-grade tooling and services—including firewall rule lifecycle management, policy drift detection, configuration compliance validation, and telemetry enrichment—using modern backend languages (Python strongly preferred) and infrastructure-as-code. • Manage and tune network-layer detection capabilities — including IDS/IPS signatures, firewall rules, and WAF configuration — to ensure high-fidelity signals for SOC consumption. • Operate at the leading edge of AI-assisted development: write precise engineering specifications, direct AI coding agents (e.g., Claude Code, Cursor), and review/validate generated output to build secure, lights-off agentic pipelines that the broader team can learn from. • Build and maintain API integrations across the network security technology stack (e.g., Cloudflare, Zscaler, cloud-native controls) with reliability, observability, and audit-readiness designed in from day one. • Support compliance audit and assessment activities — including evidence collection, control testing, and auditor walkthroughs for network security domains; maintain an accurate network diagram inventory documenting topology, segmentation boundaries, and data flows. • Partner with the Security Operations Center, SRE, and IT to ensure network security controls integrate cleanly with existing infrastructure pipelines, CI/CD workflows, and incident response processes; participate in security architecture reviews and contribute to runbook development and operational documentation—raising the network security bar across the engineering organization. • Perform other duties as assigned.
