Skylo Technologies is a global NTN service provider, offering a service that allows smartphone and IoT cellular devices to connect directly over existing satellites. Backed by Innovation Endeavors.
About the role
Every MNO onboarding ends at a technical test gate. We are hiring an automation-oriented IREG & Network Test Engineer to own that gate—from attach and authentication through SGD, MAP, SMS, IP NIDD, and roaming sign-off. You will replace manual, partner-dependent execution with a repeatable test strategy, scalable lab, and automated regression pipeline.
What they're looking for
- 5+ years of experience in roaming, mobile core, interconnect, IREG, or telecommunications network testing
- Hands-on understanding of Diameter and relevant SS7/MAP concepts, including S6a/S6d, SGd, and roaming authentication and registration flows
- Experience reading Wireshark or equivalent signalling traces and diagnosing network failures involving multiple parties
- Experience designing automated telecommunications testing frameworks using Python or comparable languages and CI practices
- Fluency with IR.21/RAEX, PLMN, IMSI, TADIG, and structured testing evidence
- NB-IoT, NTN, NIDD, IoT roaming, GSMA test-suite, or device-lab experience
More about this role
The world still has coverage blind spots. You could help eliminate them at Skylo.
Skylo has pioneered a standards-based approach to satellite connectivity. We connect smartphones and IoT devices directly to satellites. No special hardware, no entirely new networks. Just billions of existing devices, suddenly reachable anywhere on Earth. We're not building toward this future. We're already in it.
Our direct-to-device service is live on millions of activated devices across five continents, covering more than 72 million square kilometers, in partnership with leading satellite operators, mobile network operators, Tier-1 chipset makers, and OEMs worldwide. And we're just getting started.
At the heart of it all is Skylo's commercial NTN vRAN: a 3GPP standards-based, cloud-native platform that seamlessly bridges terrestrial and satellite networks. It's the infrastructure that makes true anywhere, anytime connectivity possible.
When you join Skylo, you'll work at the intersection of three markets reshaping how the world stays connected: mass-market consumer devices, automotive, and industrial IoT. Enabling people outdoors and critical workflows in the world's most remote places.
