Quality Assurance Engineer, Roaming

About the Role

Ready to make travel easier for millions? Airalo is the world’s first and largest eSIM store, helping travellers stay connected seamlessly in over 200 countries and regions. We trust our teams to take ownership, put customers first, and do work that has a real impact every day.

Hi, I’m Peter, VP of Networks at Airalo! Our team ensures customers have instant, smooth connectivity from the moment they purchase their plan to the moment they arrive at their destination. We go beyond standard mobile service, building innovative solutions that enhance the traveller experience. We’re looking for curious engineers who want to design the future of global networks. Think outside the box, reverse-engineer solutions from ambitious product ideas, and help pave the way for Airalo’s leadership as a global connectivity partner.

Airalo’s fully remote Networks team is growing. You’ll work on the systems and infrastructure that keep over 20 million travellers connected reliably and securely at global scale. Solve complex technical challenges, optimize processes, and experiment with better ways to keep the world connected.

As our End-to-end Regression Specialist, you will be the guardian of our global roaming experience. You will own the testing of roaming scenarios across our Global Connectivity Platform, ensuring that as we scale our sponsor footprint and add Direct Roaming Agreements, our service remains "carrier-grade." You will dive deep into signaling traces to ensure our travelers stay connected across continents.
