Automation and Scripting

• Experience with network automation using Python, Ansible, Terraform, APIs, Git, and CI/CD.
• Experience with capacity planning, hardware-resource/TCAM analysis, and large-scale routing-table design.
• Can partner with NW automation teams to design and develop NW modeling and configuration rendering solutions, to be able to review configuration diffs and mitigate configuration issues on NW switches.
• Designs and builds advanced modules within automation frameworks to support testing, operations, and service reliability across multiple environments.
• Automates high-impact network tasks for production and lab environments, and optimizes repetitive, cross-team workflows to improve operational efficiency.
• Develops and maintains advanced dashboards, telemetry tools, and alerting systems to enable proactive monitoring and faster issue resolution.
• Writes, enhances, and documents reusable scripts that streamline routine network operations across teams and product domains.
• Modifies and extends infrastructure pipelines and configuration management tools to meet evolving requirements using existing playbooks and custom logic.
• Independently configures and extends tools to support new products or services, ensuring alignment with platform standards and integration best practices.

Testing and Quality Assurance

• Designs and develops advanced test strategies and reusable test cases that validate complex network systems and enhance long-term network integrity and reliability, including testing network features in lab environment and rolling it out in production.
• Leads team-level test practices and cross-functional collaboration, helping define robust testing protocols and ensuring consistency in execution across environments.
• Implements and refines post-incident validation methods, integrating break-fix outcomes and lessons learned into continuous test improvements.
• Reviews and approves L1 and L2 network changes and presents high-impact changes to cross-team change management boards, ensuring risks are understood and mitigated.
• Partners with cross-functional teams to drive pre-production validation efforts, ensuring systems and environments meet compliance and deployment-readiness criteria.
• Prepares and delivers audit documentation and test evidence to support internal Governance, Risk, and Compliance (GRC) processes, maintaining alignment with security and policy requirements.

Monitoring and Reliability

• Works with others (e.g. monitoring teams) to customize dashboards, telemetry pipelines, and alerting systems, defining service level objectives (SLOs) based thresholds and metrics to monitor network health.
• Partners with monitoring and Site Reliability Engineering (SRE) teams to refine alerting systems and enhance early detection of network anomalies and degradation.
• Leads incident response during support rotations, driving root cause analysis and coordinating cross-team resolution for escalated issues.
• Builds and improves internal tools that enable frontline support teams to efficiently respond to network failures and recurring operational issues.
