Engineer II, System validation Test - Insight QA

ABOUT THE ROLE

We are looking for an Engineer II in System Validation Testing with 3 to 5 years of experience to join our cloud network management quality engineering team. The role focuses on hands-on testing of a cloud-hosted platform used to onboard, configure, monitor and manage networking devices such as access points, switches and routers.

The engineer will work with senior QA engineers, developers and product teams to understand requirements, design and execute tests, automate repeatable workflows, investigate failures and contribute to reliable releases across the device, network, cloud, API and web or mobile application layers.

KEY RESPONSIBILITIES

CLOUD NETWORK MANAGEMENT TESTING

· Understand feature requirements and expected customer workflows for cloud-managed access points, switches and routers.

· Test device onboarding, discovery, provisioning, configuration and removal workflows.

· Validate device-to-cloud communication, cloud-to-device operations and configuration synchronization.

· Test device status, statistics, alerts, notifications and basic remote-management workflows.

· Validate firmware upgrade, reconnect, recovery and factory-reset scenarios under guidance.

· Execute tests across common LAN, WAN, Wi-Fi and multi-device network setups.

TEST PLANNING AND EXECUTION

· Review user stories, acceptance criteria and functional specifications with the QA team.

· Create and maintain clear test scenarios and test cases covering positive, negative, boundary and recovery conditions.

· Prepare test data and configure required devices, accounts, subscriptions and environments.

· Execute functional, integration, system, regression, compatibility and end-to-end tests.

· Record results accurately, report coverage gaps and escalate blockers early.

· Retest resolved defects and run focused regression for impacted workflows.

API CLOUD AND DATA VALIDATION

· Test REST APIs using tools such as Postman and automation libraries.

· Validate request and response data, status codes, authentication, authorization and error handling.

· Verify consistency across APIs, backend services, database records and user interfaces.

· Test asynchronous operations, events and notifications with support from senior engineers.

· Use AWS logs, dashboards and application telemetry to investigate test failures.

· Perform smoke and regression validation in QA and staging environments.

NETWORKING AND TROUBLESHOOTING

· Apply networking fundamentals including TCP/IP, IPv4 and IPv6, DHCP, DNS, ARP, ICMP, HTTP and HTTPS, VLANs, routing, switching, NAT, LAN, WAN and Wi-Fi.

· Use ping, traceroute, nslookup or dig, iperf, browser developer tools and device or cloud logs during troubleshooting.

· Capture and perform basic analysis of network traffic using Wireshark or tcpdump.

· Isolate whether a failure is related to the device, network, cloud service, API, backend or application layer, and involve the appropriate team.
