Quality Assurance Engineer (Python & AI-Driven Testing)

Job description

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.

Responsibilities

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.

Qualifications

Core Essentials

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

Programming Basics

Good foundations in Python (academic projects, internships, or personal projects are valid!).

Problem-Solving Spirit

Curiosity, logical thinking, and strong troubleshooting abilities.

Communication

Fluency in English and eagerness to collaborate in a multi-cultural team environment.

Growth Mindset

High interest in software quality, test automation, and using AI tools to work smarter. Nice-to-Haves (Not mandatory – you’ll learn this with us!): Familiarity with pytest or Linux environments. Academic exposure or interest in optical networks, telecommunications, or networking protocols. Exposure to ISTQB concepts or AI/ML basic concepts.

What We Offer

A structured onboarding process with dedicated mentors to get you up to speed. Hands-on experience with modern CI/CD, Python testing, and AI tools. A flexible, hybrid working setup in Portugal. Clear avenues for long-term career growth within a global technology leader.
