# Software Developer, Carrier

TextNow is a full MVNO. We run our own converged 4G/5G mobile core in AWS for hundreds of thousands of subscribers, growing toward millions, and we're growing the team that owns and evolves it. AI is built into how this team works: it's how a small team operates, triages and changes a network this size. About the role Build the services between TextNow and our mobile core: subscriber provisioning, plan management, throttling and quota rules, including real-time quota tracking and policy enforcement. The team's developers also own the automated call and data checks and the lab that prove every network change is safe. That work is shared, not one person's job. No telecom background required. This is a chance to get hands-on with a real mobile network. Everyone on the team learns the mobile core and shares on-call for it. You'll ramp up alongside our Mobile Core Engineer. Where you'll work: Waterloo or Toronto area, hybrid. You come into the office about once a week. What you'll do Carrier services (most of your time): build and run Go services for subscriber provisioning, plans, throttling and quotas, with deep, real-time integrations into the core through vendor APIs.
