Key ResponsibilitiesTest Automation: Design, develop, and automate end-to-end solution test cases ensuring comprehensive coverage of networking and fiber-optic features. Framework Development: Leverage frameworks like Robot Framework, PYART, Playwright (or equivalent) to build robust, maintainable automated test suites for GUI and API testing. Evaluate and incorporate innovative, AI-based GUI testing tools to improve efficiency and reliability. Project Ownership: Ensure timely deliverables and alignment of test plans with product requirements and release timelines. Increase the automation coverage of solution test cases Mentorship & Team Collaboration: Mentor and guide junior automation engineers. Conduct code reviews, provide technical guidance, and foster best practices in the team. Collaborate closely with developers, product managers, and other QA teams to clarify requirements and triage issues. Quality Improvement: Continuously analyze testing processes and outcomes to identify gaps. Propose and implement improvements in methodologies, tools, and frameworks to enhance test coverage, efficiency, and reliability. Champion quality initiatives, such as CI/CD test integration, advanced metrics, and smarter test data management. Domain Expertise Application: Utilize deep knowledge of networking protocols and fiber optics to create realistic test scenarios (e.g. simulating network topologies, simulating customer use cases with network management system) and to troubleshoot complex issues related to network management and optical communication within the product.

Required QualificationsExperience: 5+ years of hands-on experience in software test automation and quality assurance, with significant focus on network management systems (NMS) or similar complex enterprise applications. Progressively responsible roles in test automation are expected. Domain Expertise: Strong background in the networking domain - solid understanding of L2/L3 networking protocol concepts(OSPF, BGP, ISIS, VLAN, VRF), protocols (Ethernet, TCP/IP, SNMP, etc.), and network devices. Experience with fibre optics technology and telecom networks (e.g. knowledge of optical fiber communication, GPON, XGSPON or other optical network systems) is highly valued. This domain knowledge is crucial for designing relevant test scenarios in an SMx environment. Test Automation Skills: Advanced proficiency in developing automated tests for GUI and APIs. Expertise with Robot Framework (keyword-driven testing), Playwright or similar web UI testing tools, and PYART (or comparable Python-based automation frameworks). Able to create custom test libraries and harnesses, and integrate test suites into continuous integration pipelines.

Familiarity with NMS/EMS products (such as Calix AXOS SMx, Cisco Prime, etc.) or telecom service provisioning is an advantage. Additional Automation Tools: Familiarity with other test automation and QA tools, such as Selenium, Cypress, or AI-driven testing platforms (for example, tools with self-healing tests or visual validation). Experience with performance testing tools or frameworks (for simulating load on NMS/network elements) would be a bonus. CI/CD and DevOps: Experience integrating automated tests in CI/CD pipelines (Jenkins, GitLab CI) and using containerized test environments (Docker, Kubernetes) for scalable test execution. Certifications: Relevant professional certifications, e.g. in networking (Cisco, Juniper), or testing (ISTQB Advanced Test Manager), demonstrating continuous learning and expertise.

Desired Soft SkillsCommunication: Excellent communication skills, both written and verbal. Capable of explaining complex technical concepts in simple terms to stakeholders, and documenting test plans, designs, and results clearly. Problem-Solving: Analytical mindset with exceptional problem-solving and debugging skills. Able to quickly diagnose issues in complex systems (network + software) and guide the team in implementing solutions.
