Senior Network Security Engineer

Our client is seeking a Senior Network Security Engineer to design, implement, and improve network security across a hyperscale infrastructure environment.

This hands‑on technical leadership role combines security architecture, infrastructure operations, incident response, and automation
. You will help protect critical systems and data, strengthen segmentation and access controls, and improve the reliability and consistency of security infrastructure.

Automation is central to the team’s roadmap. The ideal candidate brings deep network security expertise and practical experience using scripting, Infrastructure as Code, and vendor APIs to simplify deployment, policy management, troubleshooting, and lifecycle operations.

• Design, implement, and maintain network security controls across trusted, untrusted, and DMZ environments.
• Deploy and optimize firewalls, proxies, VPNs, threat prevention profiles, and segmentation policies.
• Apply Zero Trust principles to strengthen access controls and limit unnecessary connectivity.
• Review security architectures, traffic flows, and policy changes to identify risks and improve protection.
• Support secure connectivity across data center, cloud, and hybrid infrastructure.
• Establish consistent configuration, hardening, and operational standards across security platforms.

• Develop automation for security infrastructure provisioning, configuration, validation, maintenance, and ongoing support.
• Use Python, Ansible, Terraform, and vendor APIs to create repeatable workflows and reduce manual administration.
• Build and maintain firewall automation, policy review, and rule consolidation processes.
• Integrate security workflows with tools such as Algo Sec, Tufin, Jenkins, and Git
  , where applicable.
• Improve deployment safety through testing, version control, change validation, and documented recovery procedures.
• Automate recurring operational tasks and identify opportunities to improve consistency and efficiency.
• Serve as a senior escalation point for critical network security incidents and complex infrastructure issues.
• Lead troubleshooting across security platforms, network services, applications, and cloud connectivity.
• Develop incident response playbooks and support coordinated investigation and recovery.
• Conduct root‑cause analysis and implement corrective actions to reduce recurring incidents.
• Partner with internal security teams and external providers to improve detection, response, and operational readiness.

• Oversee network vulnerability assessments and coordinate penetration testing activities.
• Prioritize remediation based on technical risk, business impact, and operational requirements.
• Contribute to threat modeling and security architecture reviews.
• Maintain network security policies, standards, and supporting documentation.
• Support compliance with applicable security requirements and established internal controls.

• Mentor junior and mid‑level engineers and guide peers through complex troubleshooting and design decisions.
• Provide technical direction across security engineering initiatives while maintaining hands‑on ownership.
• Partner with Infrastructure, Dev Ops, Cloud, and Application teams to incorporate security into platform design and operations.
• Communicate risks, technical recommendations, and incident findings clearly to stakeholders.
• Contribute to engineering standards, knowledge sharing, and continuous improvement.

• Extensive experience in network engineering and network security
  , including hands‑on architecture and operational responsibilities.
• Demonstrated experience designing and securing tr…
