With over 175+ million users, we’re the #1 rated push-to-talk app in the world, delivering 9 billion (yes, with a B) messages a month. 

At Zello, our company values are at the heart of what we do everyday. We’re proud to serve the frontline, we’re privileged to connect people in times of crisis across the globe, and we’re honored to support first responders.

And this is where you come in.

We are seeking an enthusiastic, highly capable iOS engineer to join our AI-focused application development team.  You are an initiative-taker, excited to create meaningful impact for thousands of customers and millions of consumers every day.

You'll own projects from start to finish, working closely with our product and design team, applying scalable development patterns, maintainable code practices, and sharp technical decisions that inform and direct the architecture of the future.

We offer a high freedom/high responsibility work environment, competitive salary, and generous stock options.

After a successful first year, you will
  • Accelerate the velocity of the team by independently delivering numerous high quality projects

  • Develop a deep understanding of the iOS app's design and implementation, enabling you to clearly articulate key concepts to others

  • Enhance the codebase with targeted refactoring and comprehensive test coverage, significantly improving overall code quality

What you’ll do
  • Design, develop, test and deliver new AI-focused features for the flagship Zello iOS app

  • Improve and enhance existing code using modern patterns and practices

  • Proactively address app crashes, field issues, and customer feedback

  • Quickly master new and evolving technologies, apply them to complex challenges, and share your insights with the team

What you’ll bring
  • Deep working knowledge of Swift, Objective C (+ iOS SDK), UIKit and SwiftUI. C++ and CoreAudio experience is a plus.

  • 5+ years of software development experience for iOS

  • Published apps in the App Store - include links in your resume or cover letter

  • Clear comprehension of OOP, concurrency, synchronization, memory management and all the little things that make development complicated and interesting

  • Good knowledge of design patterns, guidelines and best practices

  • Good insight on how networks work (TCP, UDP, sockets, HTTP, TLS etc)

We hire for potential, passion for our mission, and a knack for solving difficult problems over checking every qualification box. We have competitive pay, equity with significant upside, and intentionally design our benefits to encourage healthy and well-balanced employees, from flexible work schedules to unlimited paid time off. We even offer a sabbatical after every five years of service so you’re able to pursue and enjoy what matters most to you. And of course, we wouldn’t be a technology company in Austin without a ping-pong table and free snacks in our break room. Join us!
