• Provision and manage the AWS-hosted EVE-NG virtual simulation environment from the ground up. • Recreate legacy environments by sourcing vendor firmware (e.g., Cisco, Junos, Adtran) and leveraging client-provided Site Survey Reports (SSRs) to build accurate virtual replicas of target sites. • Validate automated Low-Level Designs (LLDs) generated by the ETL pipeline by executing them within the virtual lab and confirming the correctness of routing behavior. • Cross-check generated configurations against target-state IPAM and physical site data, ensuring alignment between logical design and real-world infrastructure assumptions. • Maintain CMDB data integrity by ensuring that post-migration routing tables, As-Built documentation, and telemetry are accurately captured and updated. • Perform As-Built quality assurance by analyzing post-migration outputs (e.g., “show run”, routing tables) collected by execution teams, comparing them against simulation baselines, and publishing validated results into CMDB and As-Built repositories.
