Site Reliability Engineer OXIO is the first NeoTelco. We are building the world’s largest, most accessible, and insightful Telecom network. Our platform empowers anyone to spin up their own carrier from a browser, scaling and supporting you as you scale your network to millions of users. We ensure that users and devices are connected, and stay connected wherever they go: Cross- country, carrier, or cellular technology. We help them pay less for mobile data. This technology is provided through our Carrier-as-a-Service platform: BrandVNO, a fully customizable telecom service. In addition, we enable clients of our service to extract the value from telecom data - enriching their customer experience, business intelligence, and product understanding in the many markets in which we operate. Come join us in creating a modern technology platform with a group of engineers dedicated to advancing our vision. Our team is passionate about what we build, open to new ideas and challenges, and has our sights set on the future of connectivity.
