The Role
Client is seeking an experienced Network Automation Engineer with strong hands-on expertise in NetBrain to accelerate the automation of network incident diagnostics, evidence collection and operational workflows. The role will work alongside Network Operations, engineering, tooling and service-management teams to convert repeatable troubleshooting knowledge into secure, reusable and auditable automation.
Your Responsibilities
- Analyse incident, alert and service-management data to identify and prioritise automation opportunities.
- Design, build, test and deploy NetBrain PDAs, Runbooks, Qapps, Data Views, Dynamic Maps, Network Intents and associated templates.
- Translate existing playbooks, standard operating procedures and senior-engineer troubleshooting practices into deterministic automation workflows.
- Configure triggered and interactive diagnostic workflows for incidents and monitored events, with clear guardrails, approvals and exception handling.
- Integrate NetBrain with ServiceNow, DX NetOps Spectrum and other monitoring, observability and orchestration platforms using supported APIs and integration patterns.
- Automate collection of device state, topology, paths, configurations, logs and relevant telemetry, and make outputs available within the incident workflow.
- Work with CMDB and inventory teams to validate device, service, dependency and configuration-item data required for reliable correlation and routing.
- Develop pre-change and post-change validation, configuration-drift and compliance checks where prioritised by the product owner.
- Partner with L1, L2 and L3 network teams to validate diagnostic logic across representative incidents, vendors and technologies.
- Apply secure engineering, change management, maker-checker, testing, rollback, access-control and audit requirements expected in a regulated financial-services environment.
- Produce design documentation, support procedures, test evidence, operational metrics and knowledge-transfer material.
