• Strong Python programming skills and deep hands-on experience with pytest, PTF (Packet Test Framework), sonic-mgmt, and Ansible
• Solid background in CI/CD engineering and automated test orchestration, focused on automating provisioning, traffic generation, diagnostics, and regression testing
• Solid networking knowledge with a focus on routing (BGP, OSPF, routing tables, VRFs, Layer 3 concepts) and working with SONiC routers
• Understanding of router concepts including overlay architecture, policies, and IPsec tunnels (hands-on router experience preferred)
• Proven debugging and troubleshooting skills, including reading logs, CLI-level investigation, and isolating root causes across product, test, and environment layers
• Experience working closely with software development teams and translating delivered features into test scenarios
• Hands-on use of AI tools in everyday engineering work
• Experience with Docker
• Good Linux command-line skills including shell scripting and command-line tools
• Good knowledge of English (B2+ level)
• Proficiency with Git and CI/CD platforms

Nice to have:

• Hands-on experience with Golang, C/C++, Groovy
• Experience with SD-WAN
• Hands-on experience with router solutions
• Familiarity with Jenkins and GitHub-based CI/CD pipelines
• Experience with physical or virtual network testbeds and virtual routers
• Experience working with formal defect tracking systems
• Experience with traffic generators

• Design, build, and maintain robust CI/CD test automation pipelines and test suites in Python for pre-commit PR testing and weekly regression runs
• Automate environment provisioning, traffic generation, network diagnostics, and continuous regression testing across virtual and physical testbeds
• Debug failed runs by analyzing device, system, and test logs; distinguish product bugs from test-suite or environment issues; raise well-documented defects
• Collaborate closely with development teams to understand features and design test coverage for those use cases
• Extend test automation as new features are delivered in the Routing area
• Leverage AI tools (AI-assisted RCA, LLM coding assistants) to speed up scripting, log analysis, and root cause identification
• Coordinate issue resolution with suite owners and dev/test engineers through dedicated collaboration channels
• Manage physical and virtual testbed environments and provision resources for test execution
• Identify, analyze, and resolve flaky tests to maintain high pipeline reliability
