Original job description

US Mobile is building the future of wireless communication. The goal: one unified network open to any person and any device, worldwide. Connection without walls.

We’re getting there by empowering customers. All three major networks on one phone and one plan, plus home internet from Starlink. No lock-in. No commitments. Custom fit plans at every price point. 24/7 customer support with real people, empowered to help. We get real-time feedback from Reddit, surveys, and customer support informing product roadmaps and everything we do. It’s working - Consumer Reports named us the top-rated mobile carrier two years in a row.*

And we’re building innovative systems that scale. A network agnostic tech stack. Agile, cross-functional teams built on trust and mutual respect. This work isn’t for everyone. If you work fast, flexibly, and collaboratively - without compromising standards - we want to hear from you.

\nWhat You'll Do:

Build cross-platform mobile applications using React Native, ensuring modular, extensible, and maintainable architecture.
Modernize and refactor existing application features to enhance performance, scalability, and future-proofing by leveraging performance metrics and error monitoring platforms.
Partner closely with product and design stakeholders to create high-performance, user-friendly features with strong visual appeal.
Establish and maintain robust testing frameworks, reliability standards, and streamlined release processes as well as collaborate with QA to ensure testing coverage.
Guide and develop fellow engineers while fostering an environment focused on high-quality code, creative solutions, and ongoing skill development.
Create and maintain clear process documentation as well as contribute to development and design guidelines.
Research emerging technologies and best practices within the React Native ecosystem; present findings to the team and influence design and technical decisions.
Champion user experience across the product lifecycle, ensuring designs translate seamlessly into practical, engaging solutions.

Role Requirements:

Minimum 7 years in mobile development (with 5 years of hands-on React Native expertise). Proven track record of successfully launching applications on App Store and Google Play.
Knowledge of mobile user experience principles and the distinct characteristics of iOS and Android platforms.
Hands-on experience with continuous integration/deployment, over-the-air updates (such as Expo), and release automation.
Demonstrated ability to excel in dynamic startup settings - delivering quickly without compromising code quality.
Excellent interpersonal skills with a passion for knowledge sharing and team collaboration.

Core Technologies We're Currently Building With:

React Native (0.83+) + TypeScript
Tanstack ReactQuery
React Navigation

Benefits:

Competitive Salary
Gym reimbursement
Commute reimbursement
Flexible working hours
Professional development stipend
Flexible time off
