Software Developer — iOS (Canada)

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) and lead their rollout.

• Build and extend our internal AI harness — agents, automation frameworks, evaluation pipelines, and guardrails — so the whole team ships faster and safer; continuously evolve how you use AI and push the org's standards for what “good” looks like. • Define observability standards, telemetry pipelines, and fault-tolerance strategies for production-grade mobile systems. • Partner closely with product, design, backend, and data; drive technical discussions, mentor developers, and influence strategic direction across mobile.

Who You Are

We're raising the bar. This role is not a fit for developers early in building production systems, and our screen reflects that. Strong candidates will clear most of the following: • Deep iOS expertise.

Production mastery of Swift, SwiftUI, and modern concurrency (async/await, actors), plus comfort in legacy Objective-C. You've shipped and operated consumer iOS apps at meaningful scale. • Architect-level judgment.

A proven track record designing modular, maintainable systems that balance speed and reliability — and the ability to defend those trade-offs. • Production-readiness as a default. You architect for observability and reliability: instrumentation, SLOs/SLIs, fault tolerance, runbooks, incident triage, scalable telemetry pipelines, and live production diagnostics for mobile clients.

• Genuine AI fluency. You already use AI across your development workflow and can speak specifically about where it helps, where it fails, and how you've improved on its output. You're excited to generate most of your code with AI and to own the quality bar on top of it.

• Demonstrated technical leadership. You've influenced roadmaps, contributed to multi-team initiatives, mentored or led developers, driven process and culture improvements, and worked directly with senior engineering and product leadership. • Performance and systems depth.

Strong background in performance optimization, observability, and system-level debugging.
