Project description

Project Description: Product verification & testing for an L1-L3 Traffic Generator Solution for a Global Networking Testing and Validation equipment provider.Our team: A team of networking enthusiasts willing to contribute to customer success.Technologies used: Networking protocols, traffic generation tools, Windows/Linux servers, network virtualization, network management tools, microservices.Opportunities: Networking and testing certifications, collaboration with an international team of professionals, working with the latest networking technologies and concepts, access to training.

Responsibilities

• Design, implement and maintain long-running automated test scenarios (soak tests spanning days/weeks) using Spirent TestCenter APIs, covering performance, scalability, convergence, and protocol stability under sustained traffic load.
• Derive automation requirements from manual functional test specifications and hardware validation reports
• Collaborate with development team to translate software requirements into high-quality test automation suites
• Develop automation for the end-to-end solution validation and integrate the automation for seamless validation.
• Implement, execute and debug Python automated test scripts on Linux-based platform
• Analyze and manage automated regression test execution failures
• Debug and troubleshoot complex issues and work closely with the engineering team on the failures and validate fixes
• Integrate test suites into CI/CD pipelines
• Collaborate closely with hardware and software development teams to triage test failures and drive quality improvement
• Reproduce and root-cause hardware/firmware defects through systematic test isolation
• Make use of AI tooling (e.g. Claude Code, agentic AI) given customer-specific heavy usage patterns.
• Review customer deployments and customer-found issues and address any gaps in the test coverage.

SKILLS

Must have

• Overall QA background of 6+ years, with 4+ years in testing networking domain-related applications.
• QA Automation experience in an Agile/SCRUM team, focused on API and/or CLI testing (4+ years);Python strongly preferred (other comparable languages considered).
• Automated Testing for API or CLI 4+ years, including experience in test harness or frameworkdevelopment.
• Hands-on experience automating Spirent TestCenter (STC) using its Python API specifically StcPythonnative API, the REST-based stcrestclient library (py-stcrestclient), or HLTAPI (High Level Test API); abilityto script traffic port configuration, device emulation, traffic stream setup, result subscription and statisticsretrieval.
• Familiarity with STC Lab Server architecture: connecting to chassis, managing test sessions, andexecuting automated sequences without GUI dependency.
• Experience writing and maintaining long-running automation suites (soak tests of days/weeks duration)with robust result collection, error handling, and reporting.
• Working knowledge of L2/L3 protocols exercised through STC: Ethernet, VLAN/QinQ, BGP (v4/v6),OSPF (v2/v3), IS-IS, MPLS/LDP, BFD, and data-center protocols such as VXLAN and EVPN; abilitytoconfigure emulated/simulated router topologies for scale and convergence testing.
• Familiarity with RFC 2544 / RFC 2889 benchmarking methodology for throughput, latency, frame loss andback-to-back testing.
• Practical experience with AI tooling in day-to-day activities to improve productivity and delivery quality(code generation, code review, automation, agentic AI, MCP usage, etc.).
• Experience in performance, scale, and convergence testing; ability to analyze and improve performanceand convergence at system level.
• Ability to develop and publish solution validation documents and test reports.
• Strong verbal and written communication skills; able to communicate effectively across QA andDevelopment teams.
• Highly motivated, self-driven, and able to collaborate cross-functionally to meet challenging goals.

Nice to have

• Knowledge Linux OS variants (Ubuntu, Debian).
• CI/CD (Jenkins, GitLab, or similar) and issue tracking tools (JIRA, Confluence).
• Knowledge of STC Tcl API or legacy Tcl/HLTAPI scripting (useful for migrating existing test suites toPython).
• Familiarity with additional traffic generation or network testing tools (e.g., IXIA/Keysight, Wireshark, Iperf).
