Job Description We are looking for a Senior Network Engineer/Analyst to serve as the simulation and validation engine for a large-scale network consolidation program at a US-based Tier-2 Telco. The role focuses on building and operating AWS/EVE-NG simulation labs, replicating legacy environments, and validating automated configuration outputs before deployment to production. It acts as the final technical quality gate, ensuring that all configurations are fully tested and aligned with the target-state design. This position is ideal for professionals with strong expertise in network virtualization who thrive in validation-heavy environments and quality assurance of complex network transformations.
Responsibilities * 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.
Qualifications * 5+ years of experience in network engineering, infrastructure analysis, or technical QA, with strong focus on lab simulation * Hands-on expertise with network virtualization platforms such as EVE-NG, GNS3, or CML, along with cloud infrastructure knowledge (AWS EC2, VPC routing) * Strong multi-vendor routing and switching expertise, with the ability to confidently navigate and troubleshoot CLI across both legacy network devices (e.g., Junos, Adtran) and modern platforms such as Cisco SD-WAN edge * Ability to translate simulation failures into clear, actionable feedback for Network Architects and ETL/Automation teams
