The role includes building lab environments, performing connectivity and performance testing, and coordinating with multiple teams to ensure quality across deployments.

Qualifications

• Minimum 6 years of experience in test engineering, systems testing, network testing, or quality engineering.
• Strong understanding of IPv4/IPv6 addressing and subnetting, TCP vs UDP, DNS, DHCP, ARP, and ICMP.
• Working knowledge of HTTP/HTTPS, VLANs, VPNs, NAT, firewalls, routing, switching, Wi-Fi, and PoE.
• Experience understanding Change Requests, validating configurations, and testing store devices after changes.
• Experience executing connectivity, reachability, performance, failover, recovery, reliability, and stability tests.
• Ability to design diverse test scenarios (positive, negative, boundary, integration, regression).
• Hands-on experience with packet-capture tools; basic interpretation required.
• Experience using ping, traceroute, nslookup, dig for connectivity testing.
• Ability to diagnose connectivity issues across DNS, routing, firewall, and network layers.
• Ability to maintain traceability from requirements to tests to defects.
• Strong written and verbal communication with clear test evidence.

Responsibilities

• Identify business, technical, and operational risks and contribute to user story and requirement definition.
• Define, develop, and review test cases, test plans, test scenarios, and overall test strategy.
• Read and analyze network requirements and Change Requests; identify testable, ambiguous, and missing requirements.
• Convert requirements into test scenarios including boundary and regression tests.
• Build and maintain mock-store and lab environments representing real store networks and devices.
• Perform integration and functional testing of store devices after a Change Request is implemented.
• Execute connectivity, reachability, configuration, DNS, routing, firewall, port, and device-access validation.
• Perform network-performance testing including latency, packet loss, bandwidth, and response-time analysis.
• Execute network failover, recovery, reliability, and stability testing.
• Test POS applications, payment devices, scanners, cameras, printers, and cloud services.
• Capture logs, packet traces, screenshots, and performance measurements for defect analysis.
• Troubleshoot issues across application, device, network, security, and configuration layers; determine root cause.
• Manage defects through triage, prioritization, retesting, closure, and regression validation with full traceability.
• Coordinate test execution with Network Engineering, InfoSec, Store Operations, engineering teams, vendors, and AT&T.
• Support pilot-store validation, go/no-go reviews, production verification, and post-deployment issue investigation.
• Recommend wired or wireless implementation approaches based on reliability, security, bandwidth, cost, and maintainability.
• Improve repeatability through automation, scripting, and standardized test evidence.
• Demonstrate team-player mentality and SCRUM participation.
