Role Overview
NETGEAR is looking for a QA Automation Engineer to help validate our next-generation firewall and cybersecurity platform. In this role, you will build and maintain automated tests that verify firewall behavior across critical security domains including Next-Generation Firewall (NGFW), Secure Access Service Edge (SASE), Zero Trust Network Access (ZTNA), Secure Web Gateways (SWG), Virtual Private Networks (VPN), and Software-Defined Wide Area Networks (SD-WAN).
Working alongside firewall developers and senior QA engineers, you will automate functional, regression, and performance testing against real and simulated network traffic. You will not be expected to know every area of the stack on day one — we will support you in growing across it.
Key Responsibilities:
-
Develop and maintain automated test suites that validate firewall functionality — policy and rule evaluation, NAT, stateful session handling, and traffic filtering across NGFW, SASE, ZTNA, SWG, VPN, and SD-WAN features.
-
Build and maintain test topologies and lab environments, including virtual machines, containers, and physical firewall appliances.
-
Generate and shape realistic network traffic to exercise the firewall data plane, and verify observed behavior against expected policy outcomes.
-
Run test suites in CI, triage failures, distinguish product defects from environment and test issues, and file clear, reproducible defect reports with supporting packet captures and logs.
-
Contribute to test plans and test-case design from firewall requirements, and help keep automation coverage mapped to those test cases.
-
Support performance and scale testing — throughput, connections per second, and concurrent sessions — and help identify regressions.
-
Work with developers to improve testability, and stay current with automation tooling, including AI-assisted test generation, maintenance, and failure triage.
Required Qualifications:
-
Bachelor’s degree in computer science, Engineering, or a related technical field.
-
2–4 years of professional experience in QA automation or test engineering, preferably for networking or security products.
-
Strong automation scripting ability in Python and Bash, comfort working in Ubuntu or other Linux environments from the command line, and day-to-day use of Git.
-
Working knowledge of networking protocols and traffic flows — TCP/IP, DNS, HTTP/HTTPS, TLS/SSL, NAT, and routing fundamentals.
