Job description

Serves as a hands-on technical leader who designs, implements, and continuously improves OEC’s (OEConnection’s) enterprise and cloud network infrastructure. Works within on-premises environments — routing, switching, firewall, and load balancing — and modern cloud networking across AWS and Azure, where OEC’s SaaS platform serves automotive dealers and OEMs globally. Drives network modernization, leads architecture decisions, establishes Infrastructure as Code and automation standards, and serves as the primary escalation point for complex network problems. Mentors junior engineers and shapes the long‑term direction of the network practice.

Key Responsibilities & Duties (essential to the job)

• Designs, deploys, and operates complexLAN/WAN and data center switching environments (Cisco Nexus,Catalyst, Meraki) and administers firewalls, VPN, and F5 BIG-IP load balancers supporting production and customer‑facing workloads.
• Architects and manages cloud networking in AWS and Azure — including VPCs, VNets, Transit Gateways, ExpressRoute/Direct Connect, hybrid BGP connectivity, NSGs, and cloud‑native security controls.
• Authors and maintains network Infrastructure as Code using Terraform; enforcesa GitOps workflowwhere all cloud network changes are version‑controlled, peer‑reviewed, and deployed via CI/CD pipeline.
• Builds and maintains automation tooling in Python and/or PowerShell for configuration compliance, inventory management, and operational efficiency; integrates Ansible or NAPALM for on‑premises device management.
• Designs and owns network observability — monitoring coverage, alerting thresholds, and on‑call escalation paths using Datadog, Azure Monitor, and AWS CloudWatch; leads post‑incident reviews and drive improvements.
• Leads network modernization initiatives including SD‑WAN adoption, zero‑trust segmentation, and cloud‑first connectivity; produces HLD/LLD architecture documentation and presents recommendations to leadership.
• Serves as the senior escalation point for complex network incidents; conducts root cause analysis, documents preventive actions, and maintains the team’s runbooks and standard operating procedures.
• Mentors Network Engineers and junior staff through pairing,code review, and knowledge‑transfer; evaluatesnew platforms and vendors through structured proof‑of‑concept testing.
