Quality Assurance Engineer (Python & AI-Driven Testing)

• In an increasingly connected world, telecom networks are the backbone of global connectivity. By joining the Optical Networks division (recently strengthened by the acquisition of Infinera), you’ll be at the forefront of a team delivering high-capacity network solutions in the AI-driven data center era.
• As an Quality Assurance Engineer, you will be an essential member of a cross-functional Scrum team. We don't just "test code at the end"—we embed quality into the product right from the design phase.
• Whether you're a recent graduate or at the start of your tech career, we provide the mentorship, tooling, and environment for you to master automated testing, Python coding, and cutting-edge AI quality frameworks.
• Learn Automation & AI Testing: You won't just run manual tests—you'll learn to build modern Python automation suites and leverage LLMs/AI utilities for test generation and defect analysis.
• Mentorship & Growth: Work closely with senior developers, system architects, and testers who will help you build a solid engineering foundation.
• Real Agile Experience: Participate in every step of the R&D software lifecycle within a supportive, international Scrum team.
• Agile & Quality Mindset: Join daily scrums, sprint planning, and reviews, bringing fresh perspectives to requirement analysis and testability.
• Python Test Automation: Design, write, and maintain automated test scripts using Python and pytest aligned with CI/CD practices.
• AI-Assisted Testing: Learn and apply AI-driven testing techniques (using LLMs for test case design, pattern analysis, and automated test data generation).
• Troubleshooting: Work on root-cause analysis to help developers fix complex system bugs efficiently.

Core Essentials

• Education: BSc or MSc in Computer Science, Telecommunications, Physics, or a related technical field (graduates/final-year students welcome).
