Job description

We believe that communication belongs to everyone. TextNow is redefining how people connect by combining simplicity, intelligence, and accessibility. We’re a team of curious builders using technology to make communication more affordable and powerful for millions of users every day.

As a Software Developer - iOS, you won’t just build apps—you’ll shape the systems, architecture, and tooling that make them possible. At TextNow, Members of Technical Staff combine leadership and hands‑on coding to enable the highest leverage opportunities possible. Being able to operate strategically, as well as diving into the lowest level details is a must. You’ll take technical ownership of key mobile domains and work across mobile, backend, and data to create faster, smarter, more reliable products.

As well, AI and automation are at the core of how we build. You’ll use them to accelerate development, improve performance, detect and resolve issues faster, and continuously raise the bar for mobile development excellence.

We’re hiring Members of Technical Staff across multiple levels (intermediate/senior/staff+). Whether you’re an experienced developer looking to lead complex systems, or an early‑career developer eager to grow, we’ll align your title and scope based on experience and impact.

This role is about impact at scale. You’ll shape how TextNow builds and operates its backend systems—using AI and automation to make development faster, decisions smarter, and experiences more seamless for millions of users worldwide.

What You’ll Do

• Design, develop, and sustain high‑performance iOS applications using Swift, SwiftUI, and Objective‑C.
• Lead architectural modernization and modularization to improve scalability and cross‑platform reuse.
• Define and own the entire lifecycle of your systems: feature ideation, API design, instrumentation, deployment (CI/CD), live‑traffic monitoring, unit/UI/e2e testing, user telemetry & data analysis, experiment design (A/B tests), and continuous iteration.
• Influence and evolve our architecture: propose and lead initiatives to decompose monoliths, build shared libraries and frameworks, improve modularization, enable reuse across iOS, Android, Web; evaluate new Apple platform capabilities (e.g., new OS releases, device types, form factors, architectures) and lead their adoption.
• Apply AI‑driven tools and automation frameworks to speed up development, code analysis, testing, and reliability.
• Leverage intelligent telemetry, analytics, and optimization pipelines to improve app performance and user experience.
• Define observability standards, telemetry pipelines, and fault‑tolerance strategies for production‑grade systems.
• Partner closely with product, design, backend, and data teams to deliver seamless, high‑quality user experiences.
• Drive technical discussions, mentor developers, and influence strategic direction across mobile platforms.

Who You Are

• A technical leader with the ability to create and lead roadmaps/initiatives that align to high‑level business objectives.
• Deep expertise in Swift, SwiftUI, and modern concurrency (async/await, actors).
• Proven track record of architecting modular, maintainable systems that balance speed and reliability.
• Strong background in performance optimization, observability, and system‑level debugging.
• Experience using AI and automation to improve developer velocity, reliability, or product intelligence.
• A collaborative technical leader who thrives in fast‑moving environments and mentors others to excel.
• Passionate about creating elegant, high‑performance mobile experiences across Apple’s ecosystem.
• You architect for observability, reliability and production‑readiness: you understand instrumentation, SLOs/SLIs, fault‑tolerance, runbooks, incident triage, scalable telemetry pipelines, and production diagnostics for mobile clients.
• You have been a technical leader (not just an individual contributor): you’ve influenced roadmap decisions, contributed to multi‑team initiatives, mentored/led developers, driven culture/process improvements, and interfaced with senior developer/product leadership.

Compensation

USD $136,300 – $273,900 a year

The expected base salary range for this role is:

• United States (NYC, CT, NJ, Seattle, LA, San Diego): $136,300 – $273,900
• United States (San Francisco / Bay Area): $148,700 – $298,800
• United States (All other areas not listed above): $123,900 – $249,000
