Own the design and implementation of network security controls across on-premises, cloud, and containerized environments, ensuring that segmentation, access controls, and monitoring capabilities align with enterprise security standards and business needs.

Serve as the primary security partner to the Network Engineering and Cloud teams, providing expert guidance on secure architectures, connectivity models, and risk mitigation strategies. This includes influencing design decisions and ensuring security is embedded into new and existing infrastructure.

Lead initiatives that strengthen network security posture, such as segmenting critical systems, securing DMZ and public-facing zones, improving container network controls, and maturing detection and logging across hybrid environments.

Act as a key contributor to the organization’s threat detection strategy by ensuring appropriate network telemetry is collected, normalized, and integrated into the SIEM. Work closely with the SIEM engineer and SOC to improve alerting fidelity and visibility across the network.

Drive continuous improvement efforts by reviewing existing configurations and architectures, identifying weaknesses or opportunities, and developing actionable plans to enhance security, resilience, and operational efficiency.

Support incident response activities, providing deep network-level expertise during investigations, helping contain threats, and contributing to root-cause analysis and long-term remediation.

Develop and maintain comprehensive network security documentation, including architectural diagrams, standards, change records, and incident reports that support audit readiness and ongoing operational excellence.

Collaborate cross-functionally with security, infrastructure, and application teams to ensure consistent application of network security controls and to promote a culture of security-first design.

Provide mentorship and guidance to junior security staff and partner teams as needed. This role does not have direct reports but may provide technical leadership on projects and influence others across the organization.
