Responsibilities
- Design and build end-to-end automated test suites for authentication protocol flows, REST APIs, network policy enforcement, and device onboarding.
- Own test coverage for product domains including RADIUS/EAP, TACACS+, captive portal, and PKI by deriving test plans, implementing cases, triaging failures, and maintaining tests.
- Build and extend test utility libraries for simulated RADIUS/EAPOL clients, browser automation, certificate handling, and REST API access.
- Perform root-cause analysis of test failures, reproduce issues in lab environments, and collaborate with backend engineers to resolve product bugs.
- Review feature specifications and write test plans covering happy paths, boundary conditions, and failure modes before implementation.
- Own and improve Jenkins CI pipelines for nightly end-to-end suites across cloud and on-premises deployments.
- Contribute bounded fixes to platform code, including testability improvements, log clarity, and small bug fixes.
- Mentor junior engineers and interns on test design, debugging, and the team’s test framework.
