• Partner with network, cloud, platform, product security, and operations teams to translate security requirements into implementable designs.
• Validate architecture through design reviews, configuration analysis, packet and flow analysis, resilience testing, and post‑implementation verification.
• Conduct ongoing firewall administration and operations including policy lifecycle management, rule administration, hardening, and exception governance.

Threat Detection, Monitoring, & Incident Response

• Provide senior technical expertise during investigations involving network intrusion, lateral movement, command‑and‑control activity, privilege misuse, and data exfiltration.
• Design and improve network telemetry, logging, detection coverage, and correlation across SIEM, NDR, firewalls, proxies, DNS, VPN, and cloud network services.
• Perform or guide packet capture, flow analysis, protocol troubleshooting, and root‑cause analysis for complex security events.
• Act as a technical escalation point during major incidents and translate findings into architecture improvements, detection enhancements, and remediation plans.

Risk Management, Governance & Compliance

• Perform security architecture and risk assessments for new systems, cloud services, network changes, and exceptions.
• Author and maintain network security standards, reference architectures, technical guidelines, and control requirements.
• Align designs with relevant frameworks and requirements, including NIST CSF, NIST SP 800-53, NIST SP 800-207, and ISO/IEC 27001.
• Provide technical evidence and remediation guidance for audits, assessments, and control‑validation activities.

Cross‑Functional Collaboration & Communication

• Serve as a trusted technical advisor to IT & Engineering teams including Network Engineering, Cloud, Infrastructure, DevOps, Product Security, Risk, Privacy, and Legal stakeholders.
• Facilitate architecture workshops and design reviews, clearly documenting decisions, risks, assumptions, and required controls.
• Translate complex technical risks into practical, business‑aligned recommendations for engineering and executive audiences.
