Job Description
Domain Architect - Wireless Networking
Noida, Uttar Pradesh

Job Summary

 Network Reliability & Availability Own reliability engineering for enterprise LAN, WAN, WLAN, SD-WAN and cloud connectivity. Proactively identify availability, capacity, latency and performance risks. Analyze recurring incidents and establish permanent corrective actions. Define and track appropriate SLIs/SLOs for critical network services. Improve network resilience through redundancy, fault tolerance and automated recovery. Partner with Network Architecture, Engineering and Operations teams to eliminate recurring failure patterns. The existing network operations material already emphasizes proactive/predictive monitoring, outage prevention and engineering changes that improve availability, capacity and performance. SDWAN JD 2 2. Incident & Problem Management Provide L3/L4 technical leadership for P1/P2 and major network incidents. Perform advanced troubleshooting across routing, switching, wireless, SD-WAN, DNS/DHCP and cloud connectivity. Lead technical bridges, restore services rapidly and coordinate across vendors and infrastructure teams. Perform detailed RCA and identify preventive engineering actions. Create automated diagnostics and remediation for repeatable failure scenarios. Improve MTTD and MTTR through better telemetry, correlation and automation. This reflects the existing requirement for expert troubleshooting and technical leadership during critical network incidents. Open Requirements in J&J Networks 3. Network Automation & Toil Reduction Develop network automation using Python, Ansible and YAML. Convert repetitive operational activities into automated workflows and runbooks. Build automated network health checks, configuration validation and compliance checks. Develop self-healing/remediation use cases for common network incidents. Integrate network automation with monitoring, ITSM and source-of-truth platforms. Use GitHub/Bitbucket and CI/CD pipelines for network automation lifecycle management. Identify and eliminate non-value-added alerts and repetitive tickets. Your existing requirement specifically calls out Python, Ansible, YAML, GitHub/Bitbucket and CI/CD, with measurable reduction of operational toil as a transformation objective. bpSigned_Copy_624789 4. Monitoring, Observability & Predictive Operations Develop proactive monitoring and network health indicators. Improve alert quality through threshold optimization, correlation and noise reduction. Analyze telemetry, logs, events and performance trends to predict service degradation. Establish dashboards for availability, latency, packet loss, capacity and other reliability indicators. Drive monitoring improvements that prevent incidents rather than simply detecting failures.
