We are currently seeking a highly skilled and experienced Senior Network Engineer/Architect to join our team. This pivotal role is responsible for leading the design, implementation, and advanced support of our mission-critical, global network infrastructure. As a technical leader, the Senior Network Engineer/Architect will bring deep, hands-on expertise in Juniper and Palo Alto Networks, and a strong command of complex service provider and large enterprise technologies including BGP, MPLS, and Quality of Service (QoS). The successful candidate will ensure reliable transport for key services such as VoIP and high-volume IP Video Surveillance (IPVS), effectively bridging strategic architectural vision with operational execution.
Work activities:
Architect, plan, and deploy highly available, scalable, and secure WAN, LAN, and Data center networks using Juniper (e.g., MX Routers, EX/QFX Switches) and Palo Alto Networks firewalls
Develop and maintain the MPLS core network architecture, including L2/L3 VPNs, Traffic Engineering (TE), and Label Distribution Protocol (LDP)/Resource Reservation Protocol (ESVP)
Design and implement complex BGP routing policies for multi-homed internet connectivity, inter-AS communication, and global route optimization
Lead the network aspects of strategic projects, ensuring solutions align with business objectives, security standards, and best practices
Design, implement, and fine-tune Quality of Service (QoS) policies (e.g., queuing, policing, shaping, classification) across the network to guarantee optimal performance for critical services
Ensure reliable delivery and transport of VoIP services, including configuration and management of related infrastructure (e.g., Session Border Controllers, gateways) and their seamless integration
Architect, plan, and support the network infrastructure specifically for IP Video Surveillance (IPVS) systems, including camera-to-VMS communication and storage networking
Conduct network capacity planning and traffic analysis to accurately forecast bandwidth requirements for high-resolution, continuous recording IP cameras (e.g., H.264/H.265 streams)
Design and manage the secure VLAN segmentation and network zoning strategy for all IPVS infrastructure, including ensuring proper PoE/PoE+ power budgets on supporting switches
Configure and manage all features on Juniper SRX Series Firewalls and Palo Alto Networks Next- Generation Firewalls (NGFWs), including Security Policies, NAT, VPNs, User-ID, and Application-ID
Enforce robust network security policies for all segmented networks, including implementing 802.1x authentication for camera and other endpoint access where required
Provide Tier 3/4 escalation support for complex network incidents and performance issues, ensuring rapid resolution and root cause analysis
Utilize network monitoring tools and packet capture analysis (Wireshark) to diagnose and resolve high-level network, voice, and video stream issues
Required Qualifications:
10+ years of progressive experience in network engineering, with at least 3 years in a Network Architect or Lead Senior role
Deep hands-on expertise with Juniper Junos OS across routers (e.g., MX Series), switches (e.g., EX/QFX Series), and SRX firewalls
Expert-level knowledge of Border Gateway Protocol (BGP), including path manipulation, route filtering, and peering
Extensive experience designing and operating Multi-Protocol Label Switching (MPPLS) networks, including LDP, RSVP-TE, and L2/L3 VPNs
Proven expertise with Palo Alto Networks firewalls, including Panorama management, App-ID, Content-ID, and WildFire integration
Strong, verifiable experience in designing and troubleshooting networks that support high-volume, real-time traffic, including QoS for VoIP and IP Video
