Senior Network & Security Engineer

TTM Technologies•Remote - California, CA

About The Position

TTM Technologies is seeking a Senior Network & Security Engineer to join our global IT infrastructure team. This is a hands-on individual contributor role for an engineer who thrives at the intersection of network and security disciplines — someone equally comfortable optimizing firewall policy and troubleshooting a complex routing issue before lunch. This role operates across a large, geographically distributed enterprise environment spanning manufacturing sites, corporate offices, and data centers across North America, Asia-Pacific, and Europe. The right candidate brings deep expertise in enterprise firewall platforms, large-scale switching and routing, and the drive to automate and continuously improve everything they touch.

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

Nice To Haves

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)
Willingness and ability to travel domestically and internationally on an as-needed basis

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
