What It's Like:

The AI Platform Engineering team builds the foundational systems that power AI across T-Mobile. We design and operate shared platforms that make it easy, safe, and reliable for teams to deploy and scale AI-powered applications. Interns work on real infrastructure used by multiple teams, improving reliability, developer experience, and operational excellence.

• Produce working prototypes and documentation that inform future platform and product decisions.

Key Responsibilities:

• Build shared platform components and reference implementations that enable agent coordination, context propagation, and integration across services.

• Design and prototype observability for AI platforms, including tracing agent interactions, context flow, and failure modes

• Evaluate platform-level concerns such as scalability, reliability, and developer experience for emerging AI standards.

What It Takes:

• Strong software engineering fundamentals with experience in Python, Java, Go, or TypeScript.

• Interest in AI platform engineering concepts, including agent-based systems and context management.

• Familiarity with LLM-powered applications and agent frameworks (usage and integration, not model training).
