Senior Network Engineer

At The Intersect Group, we partner with innovative enterprises that depend on resilient, scalable, and secure networks to power their business. Our clients operate in complex, fast-moving environments where connectivity, cloud adoption, and automation are central to growth. They value integrity, collaboration, and continuous improvement—creating a culture where engineers can solve meaningful problems and see the impact of their work. This opportunity lets you influence strategic architecture while advancing best-in-class operational practices.

We’re seeking a seasoned Senior Network Engineer to design, implement, and optimize enterprise network platforms with a primary focus on data center networking and a secondary focus on remote offices, cloud connectivity, SD-WAN, security, and network automation. This role is critical to delivering robust, scalable, and secure services that keep business applications available and performant. You will architect and support Layer 2/Layer 3 environments;

integrate cloud connectivity (including Cloud OnRamp patterns) to Azure and AWS; strengthen edge and security controls; and drive automation for repeatable, high-quality operations. You’ll collaborate closely with Network Services, Architecture, Infrastructure PMs, and Information Security to ensure solutions align to standards and are delivered predictably in a plan/build/operate model.

• Design & Implementation: Engineer data center and distributed (SD-WAN) networks, including L2/L3, secure site-to-site connectivity, and cloud on-ramps to Azure/AWS.
• Operations & Reliability: Monitor performance, troubleshoot complex incidents, and execute lifecycle activities (config, firmware, and software upgrades) to maximize availability.
• Security Integration: Deploy and support next-gen firewalls, SASE, and NAC solutions; harden edge, campus, and cloud access in partnership with Info Sec.
• Automation & Tooling: Build and maintain network automation (e.g., Ansible, Terraform, Python, APIs) to streamline provisioning, validation, and troubleshooting.
• Standards & Documentation: Create and maintain network standards, diagrams, runbooks, and automation artifacts; reduce technical debt via standardization and modernization.
• Cloud & SD-WAN: Implement and optimize SD-WAN architectures and cloud connectivity patterns for resilient, high-performance access to SaaS and IaaS workloads.
• Observability: Leverage enterprise monitoring and telemetry (e.g., Net Flow, IP SLA, packet capture) and platforms like Solar Winds to drive proactive insights.
• Collaboration & Mentorship: Partner with architecture, apps, and support teams; mentor junior engineers and communicate complex concepts to technical and non-technical stakeholders.

• 8+ years of hands-on network engineering experience with a strong concentration in enterprise data center and distributed/SD-WAN environments.
• Advanced expertise in routing and switching (TCP/IP, BGP, OSPF), spine/leaf or SDN architectures (e.g., Cisco ACI, VXLAN/EVPN), and Cisco data center platforms (Nexus, ASR/ISR).
• Proven experience implementing cloud connectivity (Azure/AWS), including Cloud OnRamp patterns and hybrid routing designs (VPC/VNet, transit, gateways).
• Depth in network security platforms such as Palo Alto Networks, Fortinet (Forti Gate, Forti Manager, Forti Analyzer, Forti Client, Forti
  
  SASE), Zscaler, and legacy/support for Cisco ASA; familiarity with ISE or other NAC solutions.
• Demonstrated ability to automate networks using Ansible, Terraform, Python, CI/CD, and API-driven workflows.
• Proficiency with observability and analysis:
  Solar Winds (Orion), packet capture tools, Net Flow, IP SLA; experience with QoS, multicast, and traffic engineering strategies.
• Professional-level certifications (e.g., CCNP/CCDP/CCIE, Fortinet NSE 4–7) or equivalent experience;
  Dev Net or similar automation credentials a plus.
• Excellent communication, documentation, and cross-team collaboration skills; able to lead initiatives, mentor others, and perform in a fast-paced on-call environment.

• Experience with SD-WAN deployments and modernization programs across multi-site enterprises.
• Knowledge of load balancers, WAN optimization, Meraki, and Wireless LAN Controllers; exposure to CUCM is helpful.
• Background designing and executing greenfield builds and migration efforts (e.g., VXLAN/OTV) and developing resilient, repeatable automation patterns.
