Role Overview

We are seeking a delivery-focused Network Engineer with strong network automation experience to support ongoing network modernization, site deployments, and SD-WAN initiatives. This role is ideal for an engineer who has a background in Network Deployment and who excels at building and delivering easy to use GUI based automation scripts for production environments.

• Build automation to support new site turn-ups, network migrations, network access control initiatives, and SD-WAN deployment
• Develop or integrate front-end GUI components (internal portals, dashboards, or tooling) that simplify network delivery workflows.
• Use APIs to integrate network platforms with automation pipelines and enterprise systems.
• Collaborate closely with project managers, implementation teams, and operations to meet delivery deadlines.
• Participate in troubleshooting and remediation during deployments; feed lessons learned back into automation improvements.
• Maintain clear documentation for deployment scripts, automation workflows, and operational handoffs.

Networking (7+ years)

• 7+ years of hands-on experience in enterprise networking roles.
• Strong foundation in TCP/IP, routing, switching, and wireless networking.
• Experience deploying and supporting Cisco and Aruba campus and branch networks.
• Solid troubleshooting skills during network delivery and cutover events.

Network Automation (7+ years in production)

• 7+ years successfully using network automation in live production environments.
• Demonstrated experience using automation to:
  • Accelerate delivery timelines
  • Reduce configuration errors
  • Improve deployment consistency
• Experience with:
  • Python for network automation and data handling.
  • Ansible for orchestration and configuration management
  • Terraform for infrastructure-as-code (network modules preferred)
• Experience developing automation that produces clear reports for the Deployment team (HTML dashboards, UI elements, CSVs).
• Familiarity with REST APIs and integrating SaaS management platforms (especially Aruba Central).
• Experience using Git for version control and collaborative development.

Preferred / Nice-to-Have Skills

• Aruba certifications (ACMP, ACMA, or equivalent).
• Experience with Aruba EdgeConnect SD-WAN automated provisioning.
• Front-end or UI technologies (e.g. Flask/Django front ends, HTML, CSS, Javascript, React).
• CI/CD integration for network delivery pipelines (GitHub Actions, GitLab CI, Azure DevOps).
• Experience supporting multi-site rollouts, mergers, acquisitions, or parallel network builds.
• Familiarity with Zero Trust, NAC, or security integrations with Aruba platforms.

What Success Looks Like

• New sites and SD-WAN deployments are delivered faster with fewer issues due to automation.
• Network configurations are standardized and repeatable across environments.
• Operations and deployment teams have usable reports and GUIs that simplify day-to-day delivery work.
• Reduction in error rates and site re-touches, reduction in hours spent on site analysis and site deployment
