Responsibilities
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 organizations 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
Qualification

Strong network traffic analysis experience, using tools such as Wireshark, SolarWinds, or Splunk to support threat detection and incident response
Demonstrated success leading or owning security improvement projects, particularly in network segmentation, cloud security, or detection/monitoring initiatives
Experience integrating network telemetry into SIEM platforms and collaborating with SOC/SIEM engineers to improve alert fidelity and visibility
Experience contributing to or supporting incident response, including containment, investigation, and root-cause analysis from a network-security perspective
Preferred
Advanced understanding of securing containerized environments, including network controls between containers, container hosts, and surrounding infrastructure
Strong knowledge of securing public-facing and DMZ environments, including threat-modeling and appropriate layered defenses
Familiarity with Zero Trust principles and modern network security patterns aligned with that approach
Ability to influence architecture decisions across network, cloud, and security teams through clear communication and sound technical judgment
Excellent written and verbal communication skills, including the ability to produce high-quality documentation and explain complex concepts to diverse audiences
A proactive, ownership-driven mindset, with a focus on problem-solving, continuous improvement, and identifying gaps before they become issues
