Mobile Developer Intern Jobs

Communication belongs to everyone. TextNow is one of the largest providers of free phone service in North America, connecting tens of millions of people who would otherwise be priced out of staying in touch. We pair a free, ad-supported tier with paid plans and a growing set of intelligent features — and we run it on infrastructure we own and operate. We move fast, we measure what we ship, and we treat AI as a core part of how we build, not a side experiment. What You'll Do As a Software Developer on iOS, you'll own the systems, architecture, and tooling behind apps used by millions — operating strategically across mobile, backend, and data, and diving into the lowest-level details when the problem demands it. This is an AI-first role: using AI is not optional, it's the expectation. We anticipate the majority of the code you ship will be AI-generated, with you as the architect, reviewer, and final authority on quality, correctness, and design. You'll have access to the latest and greatest AI development tools, and you'll help build our AI harness — the agents, workflows, evaluations, and guardrails the rest of engineering relies on. We hire across multiple levels (intermediate, senior, staff+) and align title and scope to demonstrated impact, not years on a résumé. • Design, develop, and sustain high-performance iOS applications in Swift, SwiftUI, and Objective-C, with AI tooling embedded throughout your workflow. • Own the full lifecycle of your systems: feature ideation, API design, instrumentation, CI/CD deployment, live-traffic monitoring, unit/UI/e2e testing, telemetry and data analysis, A/B experiment design, and continuous iteration. • Lead architectural modernization — decompose monoliths, build shared libraries and frameworks, improve modularization, and enable reuse across iOS, Android, and Web. • Evaluate and adopt new Apple platform capabilities (OS releases, device types, form factors, architectures) a
