About the Role

We are seeking a highly skilled Perimeter Design Engineer to support strategic cybersecurity initiatives through the design, engineering, and governance of enterprise perimeter security solutions.

This role focuses primarily on Fortinet firewall technologies and will be responsible for developing secure, scalable, and resilient designs that support business growth, regulatory requirements, and enterprise security objectives.

The position will support security architecture initiatives including new deployments, infrastructure modernization, network segmentation, data center transformations, and technology lifecycle management. The Perimeter Design Engineer will serve as a technical leader responsible for developing security standards, design patterns, and reference architectures supporting enterprise security services.

You will lead technical design efforts across strategic projects and ongoing security engineering initiatives, translating business and security requirements into detailed designs while ensuring scalability, maintainability, security, and operational efficiency.

What You’ll Do

• Develop High-Level Design (HLD) and Low-Level Design (LLD) documentation for enterprise firewall and security solutions.


• Define architecture standards, engineering guidelines, technical roadmaps, design patterns, and reference architectures for firewall and perimeter security technologies.


• Perform technical assessments to evaluate:
  
  
  
  • Business requirements
  
  
  • Security risks
  
  
  • Scalability requirements
  
  
  • Infrastructure dependencies
  
  
  
  


• Design firewall policies, NAT strategies, VPN connectivity, segmentation solutions, and DMZ architectures.


• Conduct architecture reviews and design validations to ensure alignment with enterprise standards and security policies.


• Collaborate with Security Architecture, Infrastructure, Cloud, Application, Operations, and project teams to deliver secure and scalable solutions.


• Review implementation plans to ensure alignment with approved designs and engineering standards.


• Support technology lifecycle initiatives, including hardware refreshes, software upgrades, platform migrations, and modernization programs.


• Develop and maintain engineering standards, reference architectures, design templates, and operational requirements.


• Evaluate emerging technologies and provide recommendations for future adoption.


• Mentor implementation and operations teams on approved designs and best practices.


• Identify opportunities for automation, process improvement, and operational efficiency across perimeter security platforms.


• Support complex troubleshooting and root-cause analysis as a senior technical resource.


• Maintain knowledge of current technologies and emerging technologies relevant to enterprise security.
