Job Summary
A Network Reliability Engineer for SD-WAN and Cisco Meraki bridges the gap between traditional network engineering and site reliability engineering (SRE). They focus on designing, automating, and maintaining highly available, cloud-managed networks, minimizing downtime, and ensuring seamless application performance across distributed enterprise branches
Key Responsibilities
Architecture & Deployment
- Design, deploy, and manage scalable SD-WAN architectures using Cisco Meraki (MX, MS, MR, and MG series).
- Implement policy-based routing, intelligent traffic steering, and application-aware routing across multiple WAN links.
- Configure and manage site-to-site VPNs, client VPNs, and network security policies including firewalls, content filtering, and IDS/IPS.
Reliability & Performance
- Establish network observability, telemetry, and alerting. Utilize the Meraki Dashboard to monitor packet loss, latency, and throughput across the environment.
- Proactively identify and troubleshoot network bottlenecks, latency issues, and connectivity failures to ensure high availability.
- Perform root cause analysis (RCA) on network outages and implement permanent mitigations
Automation & Scaling
- Automate routine network configurations, firmware updates, patching, and lifecycle management tasks to reduce manual intervention.
- Utilize network APIs (e.g., Meraki Dashboard API) and automation frameworks (like Python or Ansible) to streamline operations and enforce configuration consistency.
- Evaluate and optimize Quality of Service (QoS) for business-critical SaaS applications (e.g., Microsoft 365, Zoom).
Collaboration & Support
- Provide L3 escalation support for complex network incidents.
- Collaborate closely with ISP providers to quickly resolve circuit or last-mile connectivity issues.
- Maintain and update network documentation, topology diagrams, and Standard Operating Procedures (SOPs).
