The bottom of this range ($136,300) is below the Level I prevailing wage of $137,093. An H-1B cannot be filed below the prevailing wage, so an offer at the floor of this band could not be sponsored as posted.
Based on the DOL prevailing wage for this occupation and worksite, a base salary of $165,131 would place this position at wage Level II. That figure is within the posted range, and I'd like to target it. This role classifies under "Software Developers" for prevailing-wage purposes.

About the role
- 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.
- This is an AI-first role: using AI is not optional, it's the expectation.
- Strong candidates will clear most of the following: • Deep iOS expertise.
Responsibilities
- 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.
- 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.
- 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
- Partner closely with product, design, backend, and data
- drive technical discussions, mentor developers, and influence strategic direction across mobile.
Requirements
- For the senior candidates this role targets, that judgment shows up as a track record.
- A track record of measurable wins - performance, reliability, or user impact - that you drove, not just participated in.
- Our goal is to offer a competitive package that reflects the impact and expertise you bring to the team.
Nice to have
- 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.
- 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.
