Responsibilities:

• Support lifecycle replacement and remediation of Juniper ACX access switches that are approaching or past end of life
• Execute Layer 2 and Layer 3 configurations, supporting both L2 terminated services and L3 handoffs into core routing platforms
• Perform access network migrations, service cutovers, and device replacements as part of a prioritized lifecycle initiative
• Deliver switching configurations supporting:
• Layer 2 services
• Layer 3 services that transition traffic to core routing platforms
• Operate in environments utilizing common routing protocols (e.g., OSPF, ISIS, BGP) as required to support service movement into core routers
• Support both legacy configurations and more modern routing/switching designs where applicable
• Work closely with the newly established switching team led by Network Engineering leadership
• Partner with experienced commercial/network engineering teams that historically owned circuit builds and service activation
• Provide hands on execution support to ensure the lifecycle initiative gains momentum and delivers meaningful impact

Requirements:

• 5+ years of network engineering experience with a focus on switching and access networks
• Hands on experience with Layer 2 and Layer 3 switching in production environments
• Experience working with Juniper ACX platforms or similar service provider access devices
• Strong understanding of service provider / ISP or MSO network environments
• Ability to onboard quickly, adapt to an existing environment, and execute independently
• Experience supporting network lifecycle initiatives, refreshes, or remediation programs
• Comfortable working in environments that blend switching and routing responsibilities
• Automation experience (Python, Ansible, or similar) to support efficiency and scale, though not required
• Prior experience working in an ISP or MSO environment with large access layer footprints
• Background supporting commercial services, access aggregation, or service activation teams
