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.\nAbout the role\nBuild the services between TextNow and our mobile core: subscriber provisioning, plan management, throttling and quota rules, including real-time quota tracking and policy enforcement.\nThe 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.\nNo 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.\nWhere you'll work: Waterloo or Toronto area, hybrid. You come into the office about once a week.\nWhat you'll do\n 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. Replace ClickOps with APIs, pipelines and config in git.\n Make usage records accurate: check that usage records (CDRs) are complete and match what subscribers actually used, and catch gaps before they show up in billing or carrier costs.\nBuild our AIOps tooling. AI agents and tools that pull together alarms, logs, metrics and config changes across the core, investigate incidents automatically and propose or run the fix.\n Own the checks (shared across the team): automated calls, SMS and data sessions that run before and after every config change and vendor rollout, with an SLO on pass rate.\n Build the lab that tests the core (shared): simulators, real devices, test SIMs and test subscribers, and the automation that drives them.\nBuild and operate with AI: design, code, tests, debugging, triaging failed runs and production issues. It's how a small team owns this much of the platform.\nWho you are\n3+ years (P2) or 5+ years (P3) building backend services in production\nStrong in Go, or strong in another language and keen to work in Go\nMicroservices on AWS and Kubernetes, CI/CD, Argo CD or similar\nYou care about integration and end-to-end testing, including on real devices\nYou build with metrics, logs, traces and SLOs in mind\nAI is part of how you build and operate: design, code, tests, debugging and production triage\nNice to have\nBuilt LLM agents or tools in production (tool calling, MCP servers, evals), or event correlation and anomaly detection on operational data\nBilling, rating, quota or entitlement systems\nDistributed event-driven systems\nDevice automation, device farms or network simulators\nTelecom, SIP or networking experience\nBase Salary Range\nThe expected base salary range for this role is: \nCanada Intermediate: CAD $113,400 - $162,000 annually \nCanada Senior: CAD $158,000 - 207,000 annually \nOur salary ranges are determined by role, level, and location. Within the range, individual pay is determined by job-related skills, experience, and relevant education or training. \nOur goal is to offer a competitive package that reflects the impact and expertise you bring to the team. \nThis posting is for a current, active vacancy.\nMore about TextNow \nOur culture \nWe’re proud of the culture that we’ve built at TextNow, but one of the most common questions we hear is ‘how do you continue to sustain it as the world and the company continues to change?’ The reality is that we’re only able to keep up because each and every TextNovian contributes to our culture through being involved, by living our values, sharing feedback, embracing change and more! \nOur values \nCustomer Obsessed \nWe strive to have a deep understanding of our customers. \nDo Right By Our People \nWe treat each other with fairness, respect, and integrity. \nAccept the Challenge \nWe adopt a \"Yes, We Can\" mindset to achieve ambitious goals. \nAct Like an Owner \nWe treat this company like it's our own... because it is! \nGive a Damn \nWe are deeply committed and passionate about our work and achieving results. \n Our benefits and more \nThis is a brief overview of the benefits that TextNow offers its employees.
