Senior Network & Security Engineer

TTM Technologies is a global manufacturer of technology products, including printed circuit boards, RF components, and mission systems. The Senior Network & Security Engineer will support the global IT infrastructure team by managing enterprise firewalls, network routing and switching, wireless infrastructure, access control, automation, and incident response across a geographically distributed environment.

Responsibilities:

• Design, implement, and manage enterprise firewall policy across a global environment — including rule lifecycle management, audits, optimization, and governance
• Provide network routing and switching support across a complex, multi-site infrastructure — including campus, data center, and WAN environments
• Support and administer enterprise wireless infrastructure, including centralized management platforms and controller-based architectures
• Serve as a technical liaison between network and security functions — owning cross-team requests end-to-end to ensure accountability and execution
• Develop and maintain automation and Infrastructure-as-Code solutions to reduce manual toil and enforce configuration consistency
• Administer and enforce network access control policies, ensuring only authorized devices and users gain access to appropriate network segments
• Contribute to network and security projects supporting ongoing global expansion, including new site buildouts and data center additions
• Participate in on-call rotation and incident response for network and security events

Requirements:

• Enterprise firewall engineering expertise — deep, hands-on experience with a leading enterprise NGFW platform, covering both security policy management and network routing integration (not just one or the other)
• Large-scale switching and routing experience — enterprise-grade LAN/WAN environments including high-density data center switching, campus switching, and routing protocols (BGP, OSPF, EIGRP)
• Network access control — experience designing, deploying, or managing NAC solutions to enforce device posture, authentication, and segmentation policy across a large enterprise environment
• Automation & Infrastructure-as-Code — working proficiency with configuration management and automation tooling (e.g., Ansible or equivalent) and version control (Git)
• CLI-first mindset — you write the commands; you don't open a ticket for someone else to write them
• Dual-domain competency — genuine, demonstrable experience in both network engineering and security engineering; candidates with depth in only one area will not be considered
• 7+ years of progressive experience in enterprise network and/or security engineering roles
• Active or recently held professional-level certifications in enterprise networking and/or enterprise firewall platforms — recognized vendor certifications at the professional or expert level are a strong differentiator
• Experience with centralized network management platforms for large-scale switch and wireless fleet management
• Familiarity with enterprise wireless architecture, including controller-based and cloud-managed deployments
• Cloud networking experience — hybrid connectivity, cloud-native security enforcement, and network integration in a major public cloud environment (Azure preferred)
• Exposure to regulatory compliance frameworks relevant to multinational manufacturing operations (e.g., data privacy, defense supply chain, export control, or similar)
