At Airalo, we're making it easier for people to stay connected wherever they travel. As the world's first eSIM store, we help millions of travelers access affordable mobile data in 200+ countries and regions around the world.

Today, we're a team of 400+ people across 60+ countries, building a product used by travelers every day. We've grown quickly, but we've worked hard to keep what matters: trust, ownership, and the freedom for people to do great work without unnecessary layers or bureaucracy.

We're fully remote by design, genuinely global, and united by a shared mission to make travel simpler for everyone.

Location: Remote.
Contract: Full-time, permanent.
Benefits: Learn more about our benefits here in this link - https://airalo-public.notion.site/Benefits-25396a97ffca81fb9bc1f0be479f1be3?pvs=74
Languages: English is our main working language day to day, so you'll need to be comfortable communicating in it both in meetings and async.

Design and maintain IREG-based test campaigns for roaming partners, network changes and service launches across Data, Voice and SMS.

Manage the test SIM and eSIM fleet, remote test probes, campaign configuration, scheduling, execution, reporting and coverage history.

Build repeatable test pipelines, integrate smoke and regression suites into CI/CD, and provide clear release gates; so that core network changes and Steering of Roaming adjustments never quietly break the existing footprint.

Define the KPIs, baselines and thresholds that tell us the service is healthy. Correlate synthetic test results with production KPIs and real customer journeys, and turn what you find into alerts and runbooks the Operations team can act on.

Design and run the tests that show our geo-redundancy behaves as designed, i.e. site failover and failback, Diameter and GTP path recovery, session survival, data consistency after a switch; and verify that our core platforms deliver the capacity they were dimensioned for, under sustained load and under signalling bursts.

Analyse PCAP, MAP/SS7, Diameter, GTP and DNS traces alongside monitoring data to isolate failures, support root cause analysis, validate fixes and strengthen regression coverage.

You've worked in telecom QA, network testing, service assurance or roaming validation.

You know how LTE/EPC fits together. Give you a registration or session flow and you'll find where it broke.

Wireshark is where you go first, not last.

You write your own automation in Python or something close, and you keep regression suites running in CI/CD.

Experience at a roaming hub, IPX provider, mobile operator or MVNO, including partner interoperability testing.

Hands-on SIM box or remote testing probe management.

Exposure to 5G roaming and VoLTE roaming, including S8HR and SMS over IP.

Familiarity with HSS/HLR, PCRF and OCS functions, and how they show up in roaming failures.

Working knowledge of GSMA roaming procedures and documents, including IR.21, IR.24, IR.35, IR.38 and IR.92.

We started Airalo to make staying connected effortless, wherever you are in the world. Today, millions of travelers rely on our eSIMs, and many of the people building the product were customers first.

Our team spans 60+ countries, united by a shared belief that great work happens when people are trusted to own what they do. There's trust to own what you do, space to focus without constant layers of process, and a clear sense of what you're responsible for from day one.

As Airalo continues to grow, so do the opportunities to learn, take on new challenges, and make a real impact - from anywhere in the world.
