📋 Description

• Create a globally consistent network architecture that improves security, resilience, cloud readiness, operational simplicity and business continuity while supporting the realities of manufacturing sites • Own and evolve global reference architectures for WAN, LAN, WLAN, internet edge, firewalls, remote access, cloud connectivity and network services • Translate business, security and operational requirements into practical roadmaps, design principles, approved patterns and lifecycle standards • Define the target architecture for SASE, SD-WAN, Zero Trust network access and secure branch connectivity, including coexistence and migration from legacy services • Establish a standard site blueprint for manufacturing, R&D, distribution and corporate locations, including resilient connectivity tiers, segmentation patterns and technology selection criteria • Act as design authority for major network changes, ensuring solutions are supportable, cost-effective, secure and aligned with the global strategy • Design resilient Azure network architectures, including hub-and-spoke connectivity, routing domains, BGP policy, VPN/ExpressRoute integration, cloud firewalls, load-balancing dependencies and high availability across regions • Identify and resolve routing asymmetry, overlapping path, failover and convergence risks across cloud hubs, branch connectivity and security enforcement points • Define secure connectivity patterns between Azure, AWS, SaaS platforms, business partners, internet-facing services and the global enterprise network • Partner with Cloud, Cybersecurity and Application teams to ensure network architecture supports availability, performance, observability and recovery requirements • Architect firewall, VPN and remote-access solutions using Palo Alto Networks technologies and related cloud-delivered security services • Develop scalable IT/OT segmentation and zone-based security patterns for manufacturing environments in partnership with Cybersecurity and OT stakeholders • Advance network access control and identity-based access using technologies such as Cisco ISE, 802.1X and complementary edge-security controls • Ensure designs follow least-privilege, defense-in-depth and secure-by-design principles while remaining practical for local operations • Define and maintain standards for switching, routing and wireless solutions across a mixed Cisco and Meraki estate • Design resilient branch connectivity using appropriate combinations of DIA, broadband, private connectivity, cellular/5G and satellite services based on site criticality and regional availability • Guide wireless architecture and optimization, including RF design fundamentals, capacity, coverage, client steering, authentication and troubleshooting of complex user-experience issues • Create repeatable deployment patterns for new sites, acquisitions, site expansions, technology refreshes and data-center exit activities • Set architecture requirements for availability, failover, monitoring, capacity and performance; validate that implemented solutions meet the intended design • Improve observability using platforms such as SolarWinds, cloud-native telemetry, vendor portals, logs, flow data and APIs • Lead technical root-cause analysis for major or recurring incidents and convert findings into durable architecture, configuration and process improvements • Optimize application experience for collaboration, voice, video and other business-critical traffic through sound routing, QoS, path selection and security-service design • Provide senior technical escalation support during high-impact incidents and planned migrations when architecture-level decisions are required • Produce clear high-level designs, low-level designs, diagrams, bills of material, decision records, standards, migration approaches, test plans and operational handover documentation • Lead architecture reviews, technical workshops, proofs of concept and vendor evaluations; present recommendations, trade-offs, risks and investment needs to technical and business stakeholders • Partner with Network Engineering, Cybersecurity, Cloud, Infrastructure, Enterprise Architecture, local IT and external service providers throughout the solution lifecycle • Mentor engineers, improve troubleshooting discipline and raise the quality and consistency of network design and documentation across the team • Support commercial and lifecycle decisions through technical due diligence, total-cost considerations, licensing analysis and vendor performance evaluation • Remain hands-on enough to review configurations, validate routing and security behavior, test failover and assist with difficult implementation issues

🎯 Requirements

• Bachelor's degree in Computer Science, Information Technology, Engineering or a related field, or equivalent relevant experience • Typically 8+ years of progressive enterprise network engineering experience, including at least 3 years performing architecture, lead design or principal-level responsibilities • Demonstrated experience designing networks for a global, multi-site enterprise; manufacturing or other business-critical operational environments are strongly valued • Expert-level understanding of TCP/IP, IPv4/IPv6, BGP, OSPF, route redistribution and policy, QoS, NAT, VPN technologies, high availability, failure domains and asymmetric routing • Strong hands-on experience with enterprise firewalls and secure remote access, preferably Palo Alto Networks and Prisma Access technologies • Strong cloud-networking experience in Microsoft Azure, including hybrid connectivity, routing, security controls, load-balancing dependencies and multi-region resiliency • Solid experience with enterprise routing, switching and wireless technologies; Cisco and/or Meraki experience is preferred • Practical understanding of SASE, SD-WAN, Zero Trust, network segmentation, NAC and identity-aware access • Ability to create high-quality architecture documentation and communicate complex technical decisions clearly to engineers, leaders and non-technical stakeholders • Professional fluency in English and Spanish, both written and spoken, to support global collaboration and effective partnership with the Matamoros site • Ability to participate in planned off-hours changes or critical-incident support when business needs require it
