Senior AI Engineer - Voice Biometrics & Conversational AI

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.

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.
