Engineer II, System validation Test - Insight QA

Overview

Hands-on system validation testing of a cloud-hosted platform used to onboard, configure, monitor and manage networking devices such as access points, switches and routers, working with senior QA engineers, developers and product teams.

What you'll do

• 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.
• 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.
• 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.
• 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.
• Develop and maintain Python-based automation for APIs, device workflows and regression scenarios.
• Create or update UI automation using Playwright, Selenium or an equivalent framework.
• Follow existing framework standards and build reusable, readable and maintainable test components.
• Analyze automation failures, distinguish product defects from script or environment issues and fix tests within assigned scope.
• Run automated suites through CI/CD pipelines and report failures with supporting evidence.
• Identify stable, repetitive manual scenarios suitable for automation.
• Log clear defects with reproducible steps, expected and actual behavior, logs, screenshots, API traces and packet captures when applicable.
• Participate in defect triage, daily stand-ups, sprint planning and test-status discussions.
• Collaborate with software, cloud, firmware, networking and mobile teams to reproduce and resolve issues.
• Track assigned defects through retest and closure and communicate risks or delays promptly.
• Maintain test cases, automation and technical notes in the agreed repositories and tools.
• Support release regression, production smoke testing and post-deployment validation as assigned.
• Verify critical customer workflows after deployments and provide accurate test status to the QA lead.
• Assist with reproducing customer-reported or production issues in controlled environments.
• Contribute new regression tests for escaped defects and recurring failure patterns.

What you'll need

• 3 to 5 years of software QA or system validation experience.
• Hands-on experience in functional, integration, regression and end-to-end testing.
• Working knowledge of TCP/IP and core networking concepts.
• Experience testing REST APIs and interpreting JSON request and response data.
• Programming or test-automation experience using Python.
• Exposure to UI automation using Playwright, Selenium or an equivalent tool.
• Ability to analyze logs, reproduce issues and write clear defect reports.
• Experience using Git and working with CI/CD test execution.
• Good written and verbal communication skills and the ability to work in a cross-functional team.
• Bachelor's degree in computer science, Information Technology, Electronics, Telecommunications or a related discipline, or equivalent practical experience.

Nice to have

• Experience testing cloud-managed networking or network management platforms.
• Hands-on exposure to access points, switches, routers or Wi-Fi test environments.
• Familiarity with AWS services, microservices, Docker or Kubernetes.
• Experience with Wireshark, tcpdump and basic packet analysis.
• Exposure to mobile application testing, performance testing or API security testing.
• Awareness of Wi-Fi 5, Wi-Fi 6, Wi-Fi 6E or Wi-Fi 7 concepts.
• Responsible use of AI-assisted engineering tools such as ChatGPT, Claude or GitHub Copilot for test design, automation, debugging or log analysis.
