Full Stack Engineer – Build the Telecom Infrastructure for NextGen

OXIO is the world's first telecom-as-a-service (TaaS) platform. We are democratizing telecom and making it easily accessible for brands and enterprises to fully own and operate proprietary mobile networks designed to support their own customers needs. Our TaaS solution combines multiple existing networks into one single platform that can be seamlessly managed in the cloud as a modern SaaS offering. And it gets better - with full network access comes unparalleled business intelligence and insights to help enterprises better understand customer and machine (M2M) behavior. With a continuous focus on innovation, any company can build a powerful telecom presence with OXIO, and in addition help them glean unique customer insights like never before.

Job Description:

Mobile connectivity is a scarce resource for most people [1]. Its affordability varies wildly from one country to another. The cost of a 500 MB of connectivity represents 30 minutes of work for an American while it's 40 hours for a Mexican. Furthermore, when traveling, people either have to pay roaming fees or face the friction of dealing with local carriers.

Something has to change in the telecom space, and our proposition is a unified exchange on which actors such as carriers, Mobile Virtual Network Operators, IoT providers, phone makers and many more can trade connectivity to drive prices down and enable new experiences for users and businesses.
