Get hands-on experience, training—and a leg up on a bright future.

Learn. Achieve. Build a Career.

T-Mobile is revolutionizing the wireless industry for millions of customers nationwide. Working here means rolling up your sleeves and redefining the status quo with a team that has your back every step of the way!

This is a 11-week paid learning experience during which you'll be able to connect and network with other interns and leaders within the company. We invite you to come innovate with mentors who will challenge you to develop meaningful skills. You'll contribute your creativity and outstanding ideas, while working alongside T-Mobile employees. We'll give you hands-on projects and the chance to create an immediate impact.

What It's Like:

This role is critical in designing, building, and scaling the core execution engine that powers T-Mobile’s IntentCX agentic AI experiences across mobile apps, web platforms, and customer support channels—including both text and voice interactions. You will architect and implement software systems that enable AI-driven decisioning, orchestration, and dynamic customer engagement at massive scale.

What You'll Do:

You will build and iterate on the software components that power T-Mobile's IntentCX program. You will build across modalities (chat and voice) using OpenAI's chat and realtime voice models. You will focus on either customer service, helping to answer questions and integrate customer data, OR on how T-Mobile sells its products. You will have a direct impact to hundreds of thousands of customer interactions every day!

Key Responsibilities:

Working closely with AI/ML engineers, platform engineers, and product teams, you will create reliable, high-performance components that allow our agentic AI to plan, act, and respond intelligently in real time across conversational modalities. This includes developing microservices, workflow engines, and integration layers that connect large language model (LLM) reasoning with network, billing, account, and support systems.

What It Takes:

• Coding experience (Python is usually key for AI work)

• Understanding of how APIs work

• Problem-solving mindset: you need to figure out what customers actually need, not just build cool tech

• Communication skills to explain technical work to non-technical stakeholders

• Ability to work cross-functionally with product, engineering, and business teams

• Comfortable with ambiguity: AI projects rarely have clear-cut answers

• Experience with LLMs, prompt engineering, or chatbot frameworks

• At least 18 years of age

• Legally authorized to work in the United States

• High School Diploma or GED

• Candidates must be currently enrolled in a degree program and have at least one semester remaining following the internship
