Job Description

US Mobile is on a mission to revolutionize connectivity. Imagine a world where you can go into a single app and buy terabytes of data for every one of your devices: phone, smart devices, car, home broadband, and more. That’s the future that US Mobile is building: a software platform built truly for the 21st century and the age of 5G and IoT, with world class engineering, best-in-class user experience, and features that will define the next generation of connectivity.

At the core of it all, we have a team and culture that has been recognized by Forbes as one of the top 500 best startup employers in the US. Our team spans diverse backgrounds, cultures, and stories, with employees coming from 20+ countries.

We're a venture-backed company entering hypergrowth, having recently ranked 94th on Inc 5000's fastest-growing private companies in America, and we’re looking for someone exceptional to join our team.

We’re looking for a Senior AI Engineer to lead the evolution of our voice technology stack. Your journey will begin by spearheading our Voice Biometrics and Authentication framework—ensuring our systems are secure and identity-aware. As you establish this foundation, you will transition into architecting the future: Next-Generation Voice AI Agents. You will play a pivotal role in moving beyond simple commands toward creating sophisticated, secure, and human-like conversational entities that can verify, understand, and assist users in real-time.
