The ideal candidate will have extensive experience with Cisco SD-WAN, enterprise routing and switching, and leading complex network migrations across multiple locations.

Key Responsibilities

• Lead end-to-end network integrations for newly acquired companies, including discovery, architecture, migration planning, and execution.
• Assess existing network environments, including WAN connectivity, circuits, carriers, firewalls, wireless infrastructure, and IP addressing.
• Design and implement target network architectures utilizing Cisco SD-WAN.
• Develop migration strategies for transitioning legacy networking environments, including Palo Alto, Fortinet, and Meraki, onto standardized Cisco infrastructure.
• Design interim VPN connectivity, address overlapping IP spaces, and establish network segmentation and security standards.
• Plan and execute network cutovers across offices, remote locations, and other distributed sites while minimizing business disruption.
• Collaborate with security, cloud, infrastructure, and application teams to support Azure connectivity and enterprise integrations.
• Leverage Python and Ansible for network automation, configuration, and deployment activities.
• Lead and coordinate onsite engineers and field technicians throughout migration projects.
• Develop technical documentation, migration plans, rollback procedures, and implementation runbooks.
• Support onsite cutovers, including occasional nights and weekends.

Required Qualifications

• 8+ years of experience in network engineering, including enterprise network architecture and migration projects.
• Extensive hands-on experience with Cisco IOS/IOS-XE and Cisco SD-WAN architecture and implementation.
• Strong knowledge of BGP, OSPF, enterprise routing, and switching.
• Experience with Cisco ISE and 802.1X network access control.
• Strong understanding of Azure networking and cloud connectivity.
• Hands-on scripting and automation experience with Python and Ansible.
• Proven experience designing and executing large-scale network migrations and site cutovers.
• Experience coordinating field engineers, technical teams, and cross-functional stakeholders.
• Ability to independently own network architecture, migration planning, risk management, and implementation.
• Must meet U.S. person eligibility requirements.
• Must be willing to travel for site migrations and cutovers.
• Flexibility to support night and weekend cutovers as needed.

Preferred Qualifications

• CCNP certification.
• Experience with AWS networking.
• Enterprise wireless design and site survey experience.
• Experience supporting distributed environments within construction, energy, utilities, or similar industries.
